Abstract

The monitoring and controlling system of endemic diseases has a vector capturing device (1 ) for capturing vectors (e.g. mosquitoes), where an evaluation standard method (2) is utilized for the captured vectors. A standardized/ codified reports system (3) provides reports about the capture of vectors. The standardized and codified reports (4) are adapted to various ways of transmission at a distance. A data input system (6), complementary information sources (7A) and a software and database (8) are introduced to emit alarms and to output reports, as well as to forward alarms and reports by using telecommunication systems to concerning places and social spots for advising public health attitudes. The vector capturing device (1 ) is a trap to capture mosquitoes with ovipositional synthetic attractant consisting of an upper cup (11 ), a lower cup (12), a funnel with an exclusionary screen (13), positioning rings (14), a cylinder with an adhesive card (15), a level control hole (16) and an upper opening (17). The lower cup (12) contains a support (19) for the attractant (18).

Description

"MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES".
STATE OF THE ART A - Among the Health Sciences, Public Health stands out due to the fact that its aim is collective, and in it, the Epidemiology stands out in relief for referring to the diseases whose etiologies have particular dynamics. Man's descendants receive two inheritances: the genetic heridity and that one from Culture. According to Ralph Linton "...without Man there wouldn't be Culture, but without Culture there wouldn't be Man."
Culture is (also) a prospect for effective control : "An ounce of prevention is worth a pound of cure", people's knowledge says. Man's genetic heredity has been providing, since his beginnings, his capacity to survive various epidemics.
It is proper for them to come unexpectedly and to spread very fast, like the Great Medieval Plagues that attacked Man in a time of his History when he didn't have enough Culture to predict nor to take preventive or curative actions. Therefore, it is comprehensible that Humanity has tried to understand these tragedies beyond their first interpretations which regarded them as "God's punishments", that is, they have tried to make Science. It is Culture that enabled Man to act over his own immune system and create vaccines, sera and defenses against the environmental agressions and even against self-agression.
It can also be said that Culture is the addition of the technologies which allow six billion men share the Earth and the presence of their alike.
B - Epidemiology: - Endemic diseases, Epidemics, Pandemics.
In Public Health, the Health Science acts are not applied only to one isolated patient but to all society, in order to prevent the malady from spreading, to cure the infected group, to protect the healthy group that still hasn't been reached and to stop the harm from returning, doing all of this as fast as possible; for this reason the Epidemiology stands out in relief. Thus, the medical-scientific knowledge isn't enough; it is necessary to turn it into action to all society soon in order to become socially effective. The key concepts are: - for all the population, prospects with enough anticipation for effective measures, preventive and curative measures and fast actions..
It is blatant that the prospect/prevention idea as a way to avoid or minimize the maladies that appear from time to time may be unavoidable: - we still can't stop a cyclone from happening, but we can foresee it with a reasonable anticipation, protect from it - or run away - and reduce the number of victims.
Public Health clearly shows Man's historical walk in the sense of the distribution of the pearls of wisdom among all men: - even if all old knowledges could have prevented, avoided or even cured great harms, these knowledges weren't applied into practice by that society to protect all men.
Historical records report that Cleopatra (10 B.C.), by following the court's doctors' pieces of advice, submitted herself to be injected with the exudates from the cattle shepherds' wounded hands to protect herself from the smallpox which was endemic in Egypt.
The proof that this technique was already well-known in that time is that the queen ordered the "vaccination" to be carried out in a hidden intercrural region so that the process scars would be very private. This very resource was then brought to light - it isn't known whether by historical culture or by personal observation - by a- modest provincial physician from England named Jenner, in the beginning of the Eighteenth Century, who let his contemporaries know that he could free them from the harms of the serious smallpox by producing a minor one (smallpox) as Cleopatra had done .
As this prevention came from the cow, the process was called by its Latin term vaccine. Over 20 centuries had gone by between these facts when the smallpox killed millions of people and left many others disfigured. It was a very powerful and cheap technology on hand, of insignificant cost and wonderful benefits, which, however, wasn't brought to serve the people, although it had been the inspiring source for Pasteur who, by searching the "filterable attenuated viruses", happened to develop the anti-rabies vaccine . Nowadays, the universal and mandatory vaccination for several diseases is one of the greatest social accomplishments of Humanity. In Public Health, knowledge must be turned into practice to benefit everyone; and as is it everyone's, what is the public's, the public stuff, the "res" public, this is the first commitment Of the modern State; - the obligation to ensure everyone the right to life .
In other words, Science is worth nothing unless it is put into practice in time to benefit everyone, that is, unless it is turned into technology at service for everyone.
The two first "epidemics" defeated by the conjunction of the scientific knowledge generation and its immediate practical use by the social tissue were the State action results and they didn't attack men, but the vineyards and the sheep livestock . Luiz Pasteur, a researcher who worked for the French government, was requested to intervene in order to prevent the French wine industry from collapsing, in the century XIX, whose grapevines had been attacked by a sudden and huge proliferation of the homoptera Philloxera vitifoliae that not only destroyed the plants, but also contaminated the. fruits, making the natural fermentation not to stop at the moment of producing only alcohol, but going further up to the acetic level, which caused a serious economic crisis. Pasteur's intervention effects turned him into a national hero: - the popular knowledge showed him the vector - the insect - and he identified the organism which produced the acetic fermentation, ordered the extermination of the insect and the equipment sterilization, destroying the harm.
At the second time, Pasteur acted on a plague which decimated the sheep livestock; he identified the "agent - the bacterium Bacillus anthracis and prescribed not the cure for the contaminated livestock but its eradication, burning and deep burial of the carcasses so that the contamination didn't spread .
C - Fundamental technical concepts of the State of the Art in Public Health. The previous introductory conceptualizations establish the concept that Public Health is a set of Health Sciences - generated by any means - made available to Society; Science turned into practice is Technology. The Public Health Technology has two inseparable features: - the first one, the scientific knowledge; the second one, the political will and technologies for social action.
The scientific knowledge is responsible for understanding and showing ways to predict, prevent and operate solutions for the cure of what is already settled.
The social action is in charge of providing education and cooperation about the Hygiene norms, in short, the public action in the sense of following the scientific knowledge rules.
The evolution of the State of the Art lies, at times, on one feature and, at times, on the other, and , at times, on both simultaneously . It is naive to believe that just by showing the harms of the endemic diseases and the advantages of the hygiene, the population will tend to observe them. The AIDS epidemic that devastates Africa could be simply and economically avoided by a mere mass communication that prescribed the use of very cheap condoms. However, although the illness agent is known - a virus - and its vector is the Man, its predominant means of transmission is the voluntary and conscious sexual intercourse, the second face of the Public Health fails and the epidemic goes on.
Usually after scientists identify the origin of the harms and show ways for their cures and if there is political will, simple attitudes bring great results. The elimination of the endemic visible goiter(IDD) from the Brazilian mid- west came along with the legislation that obliges the iodine addition to the kitchen salt; the incidence of child-cavity has decreased very much by the simple gargle with sodium fluoride which is given in primary schools . It is important to state that the Public Health bonus implies in the onus for individual commitment with the Hygiene rules. What's it worth for an individual to keep their home free of endemic diseases vector mosquitoes larvae reproduction if their neighbor doesn't? It is the State's responsibility to respond with Education and strong action in cases that threaten everybody. D - Other State of the Art contributions.
As we restrict ourselves to the Epidemiology for human application, it is important to define some concepts:
1 ° - As for the dynamic meaning of the terms: Endemic disease - disease that constantly exists in .a certain place, in a hidden or shown way.
Epidemic - a soaring aggravation of an endemic disease.
Pandemic - epidemic of big proportions as for the number of affected people and/or area. An out-of-control endemic disease may evolve to an epidemic and reach pandemic dimensions.
2° - As for the basic differences between the endemic diseases caused by organisms and by environmental factors and by means of infection: An endemic disease may have as a cause non-living environmental agents, such as, the skin cancer incidence over the European immigrant population in the sunny mountains in Southern Espirito Santo Brazilian state; the nutritional lack of iodine or the nutritional lack of fluoride that causes a higher vulnerability of the dental enamel to the commensal buccal flora. They are diseases which are not transmitted by vectors or human contact, that is, they do not spread.
The two following types are the most dangerous ones because they spread easily.
In the case of organisms whose populations spread through direct human contamination, the hygienic, environmental, social and cultural factors are predominant as causing the spread, the same is applied to getting its control as there is no exclusive vector besides the social life acts: In the endemic diseases that need vectors to spread, notedly hematophagus arthropods - and insects among them - their spread laws are more subjected to the populations' dynamic laws.
These populations' dynamic laws have been enriched by the Chaos Mathematics since the mid 70's.
The Chaos Mathematics is the modern Math that treats the nature fenomena in which a little change of the initial conditions may lead to countless big results . The first mathematicians liked to refer to this characteristic as "the butterfly that flaps its wings in the asian jungles today may cause the cyclone on the coasts of North America tomorrow".
Something like - possibly - the Black Death in the European Middle Ages: - the fleas from a sick rat that arrived on a ship contaminated the other rats in the cereal warehouse of the port. From there, they went to the inns, churches, travellers and, a month later, to the whole Europe, making millions of victims.
We cite this fact to reinforce the "explosive potential" that is inherent in the dynamics of the populations when we refer to the endemic diseases caused by microorganisms; further informatin may be found in "Nearly One- dimensional Dynamics in Epidemic" by William M. Schaffer and Mark Kot, Journal of Theoretical Biology, 112 (1985) besides other numberless references cited in CAOS, James Gleick, Editora Campus, (1989) 12nd Edition, pages 76/77. In short, for each case, the State of the Art in Epidemiology has a historical practice and a distinctive resource arsenal, and it is basically conceptual . It is consisted of the elements listed as follows: 1st - a scientific knowledge,
2nd - a social knowledge capable of applying this scientific knowledge effectively in all society, 3rd - coordination of this scientific knowledge with the social action knowledges for a continuous prevention up to a total control or disease elimination and for cure intervention exercise and the isolation in manifest cases,
4th - the capacity of the union of the scientific and social knowledges to pinpoint preventively the development seasonality or the extemporaneous emergencies of endemic diseases soon after the first signs,
5th - the capacity of taking action fast, 6th - being economically bearable to society.
DETAILED DESCRIPTION OF THE INVENTION The MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES and/or epidemics, whose patent is described, is consisted of the State of the Art advances in all the elements described above - as it will be shown - and it is composed of :
1 - A way for capturing vectors which can be applied during any of the significant steps of their biological cycles;
2 - A standardized quantifying and estabilishment process of the vectors' infestation degree that generates standard reports ;
3 - A data forwarding system that uses the sources of telecommunication, tele-localization and computer science for the immediate communication of the data generated by the analysis of the captured vectors to an automated center;
4 - A software - and its own database - that is updated as new data are introduced, it is able to emit alarms and output reports and forward them , through the telecommunication systems, to the concerning places and social spots, advising the Public Health attitudes.
5 - The capacity of the software to incorporate the epidemic backgrounds into its database and to monitor the climatic (weather) conditions likely to have the endemic diseases development and the medical-hospitalar demands and to "learn" from the processed episodes in a continuum technological creation for the Public Health.
The advances in the State of the Art and their social advantages are summarized as follows: 1 - As for the capture: it uses economical safe traps of a high degree of particularity, extremely easy to be operated by health agents with very little degree of professional specialization and a low operational cost, advancing the first element ot the State of the Art for it is consisted of a new scientific knowledge and also advancing the sixth, for it is more economical than the previous processes in use .
2 - As for the great operational speed: - due to the fact that the collected data are standardized and transmitted rigth away , whether via text or voice celular telephone, or conventional voice telephone, or the internet, or mobile radio units, the necessary measures may be taken at speeds which are compatible with the high-speed telecommunications and computer science, which minimizes the social damages and brings great economies with the Public Health, thus notably innovating the fifth element of the State of the Art by incorporating the telecommunication and automatation speeds into its practice, which automatically innovates the sixth element related to the costs. Instead of paper reports of long, broken up, expensive and bureaucratic trajectory, as more citizens are reached by the simple use of a telecommunication system.
3 - As for the technology formation and diffusion in Public Health: - the experiences can be immediately shared with other research and action centers with a continuous and economical improvement, thus advancing the State of the Art, especially the second, third, fourth, fifth and sixth elements.
4 - As for security: in spite of all preventive actions and the attempt to eradicate the endemic diseases, they may arise at any time and, as the social and economical costs will be lower the sooner they are detected, the system is always alert, it monitors the medical-hospitalar demands - especially the extemporaneous ones -, the weather conditions and the cycles of the vector population variations, and it acts accurately, or not, according to the program before the firsts signs. As it is a Public Health system with great commitments with society, it investigates the signs until they are confirmed or withdrawn, thus advancing the State of the Art in all its six elements. The techniques to catch the vector mosquitoes kept being developed and they are described in the documents WO2000/59300 and W01999/026471 , both with the same title, "Insect Trap".
Besides the documents cited above, this present patent's applicant himself is the inventor of the patent filing request No PI0203907-9, "ARMADILHA
PARA CAPTURA DE MOSQUITOS" (TRAP FOR CAPTURING
MOSQUITOES), filed on 09/05/2002 (September 5th, 2002).
The Public Health knowledges take the diseases such as dengue, yellow fever, filariasis and many others as "endemic" ones, that is, their patogenic agents resist to the human intervention and survive , either in infected men or in infected animals, and have an outbreaking power and they may become an epidemic soon after the human efforts fail and the vector population grows.
Thus, in order to keep such endemic diseases insignificant and unlike to become epidemics, the most effective action is the vector population control, which can be done with the population participation by simple attitudes such as destroying water pools like old tires, bottles, etc..
Although it is simple and despite the sanitary authorities's efforts through the mass means of communicaton, the measures above are not always optimized and the country is usually staggered by the news of one more epidemic outbreak.
So that the control over the vector insect population is more effective, it is necessary to monitor all the risky areas, which must be done by placing traps for such insects and by analyzing periodically the number of captured insects, whose data are processed with computerized resources, in parametric comparisons, that have the power of starting the public system for controlling endemic diseases and take immediate action to prevent the disease from spreading.
The process key word is disclosed: - Methodical capture of vector insects, entry spot in the automated, system, "input", sine qua non condition of the scentifically based actions. That is exactly where the weakness of the State of the Art of the capture is evident and that the "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" comes to advance it. Such advance in the State of the Art is the fruit of years of research and it is based upon a great experimental work and it means the gain of the maximum efficiency in capturing hematophagus mosquito pregnant females, that is, it means the gain of reliable numbers, which is not acquired by the current State of the Art. Actually, if the traps for capturing insects have a poor functioning and catch fewer individuals than it might have caught, this implies in fake data for the subsequent processes, which includes that of the highest severity and it is able to generate results that are more dangerous than underestimating the vector insect population. It is important to remember that all the traps of the State of the Art are consisted of contatiners which are able to keep a certain amount of water in its lower part and of devices with glue or others that can capture the females that look for these ecological micron-niches - shady places with water - for oviposition. The traps may be designed both to allow the oviposition - and the counting of eggs - and to catch the adult winged insects.
ADVANCES IN THE STATE OF THE ART PRODUCED BY THE "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES".
The present patent advances the State of the Art for the following innovative characteristics:
1 - For the size of the trap: - it has the optimum experimental volume of two liters; 2 - For the volume of water kept in it: - it keeps preferrably about 10% of its volume of water in its interior, which allows to space out the researches' visits for every thirty days, which brings along great economies to the monitoring system; its design has a hole at the right height so that it cannot be filled with a greater volume of water than the planned one, without that such hole is reached and that the excess of water flows out of it; 3 - For the geometry of the trap: - it has such shapes and accessories that thoroughly prevent the females that enter it from evading, which means that it shows reliable results about the population density of the vectors; the exclusionary screen prevents the winged insects that penetrated it from going back and the cylinder with an adhesive surface captures them soon after they have landed to lay eggs; 4 - For the use of chemical attractants: - it attracts the vectors intensily throughout the time of the operation for it uses chemical attractants immersed in specific resins for their slow release that is compatible with the complex Etiology and Physiology of the vectors, that is,' the release of the chemical attractants is slow, constant and controlled, it is neither excessive nor insufficient, which would respectively move the vectors away or not to attract them properly, bringing great distortions to the results. 5 - For being durable and economical: - it has such design resources that make it easy to be put up and disassembled and it has- pieces that can be attached to each other, thus decreasing the transportation and storage costs radically.

9. output system The Figure 2 is a "blown up" frontal view of the trap (10) used in the MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES, the upper cup (11), the lower cup (12) attachable for transport and storage economical reasons, the funnel with the exclusionary screen (13), the positioning rings (14), the cylinder with the adhesive card (15), level control hole (16) and the upper opening (17); the lower cup (12) in this Figure 2 shows a partial cut to illustrate the attractant (18) immersed in resin of slow release and the support (19) for the aforesaid attractant (18). The "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" (10) is manufactured preferrably of black dull PVC polymer that, according to the experiments, should have preferrably two liters of internal volume, with a robust construction purposed to have a long useful lifetime and approximately 10% of its total volume in its lower cup (12) should be of water. It works as follows: - the hematophagus mosquito pregnant females have humidity sensors that make them find the water pools for oviposition; once they have found them, they instinctively choose the most hidden and discreet ones. Thus, the presence of water in the device is itself an attractant for the insect, which is reinforced by the presence of the attractant immerged in the resin of a slow release (18) fixed to the support (19) of the "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS ' TO CAPTURE MOSQUITOES" (10). Thus, being drawn by the presence of water and by the right dose of the attractant immerged in resin of slow release (18) that evaporates and reaches the surroundings of the device, and without being repelled by bright colors, the female finds the upper opening (17) in which the humidity and attractant immerged in resin of slow release (18) concentrations are maximum, it enters the trap having its way determined by the funnel with the exclusionary screen (13) that goes through the adhesive card cylinder (15), being the two last pieces kept in position by the positioning rings (14) that make the device put up and disassemble process easier for the replacement of the adhesive card cylinder (15) and of the attractant immerged in resin of slow release (18) and for the water refill for a new capture cycle. Thus, drawn by the elements that define its behavior - water and attractants in discreet settings -, the internal shape of the .device forces the hematophagus pregnant female to penetrate the interior of the aereal space of the adhesive card cylinder (15), on whose wall it lands for oviposition and where it gets caught by the glue that is present in it.
The device dimensions and shapes are in such a way that the females cannot go back through the adhesive card cylinder (15) towards the upper opening (17); in case they try to leave the place, they touch the walls of the offered space where they get stuck.
Thus, the great power of attraction and capture makes that the conception of the "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OPPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" (10) to be constituted of a device whose innovation is confirmed by the efficiency in reaching the aims to which its purposed, as proved in the following Tables and which are part of the scientific research that presided over the innovative actions that guided its construction, which optimized all the factors that influence with the capture of the hematophagus mosquito pregnant females'.
The Table 1 below shows the optimum volume of water so that the "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" (10) can be in operation for at least thirty days.

The Table 2 below indicates the evaporation profile of the attractant immerged in resin of slow release (18), in which it can be seen that soon after the placement of such device, it is exhaled intensely for about five days, for soon after reach a rate of minimum evaporation, but according to the optimum parameters of capture. The intense initial evaporation is beneficial to the process for, as the device is placed in discreet and hidden spots protected from wind currents, the attractant reaches large areas with the subsequent increase of its power of attracting the insects .

The chemical composition of the attractant is a blending in various proportions of nonanal and decanal, immerged in polymer resins that do not repel the mosquito hematophagus females and thus form the attractant immerged in resin of slow release (18). The "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" (10) simulates accurately the favorite places for oviposition "in natura" of the pregnant females of the genera Aedes, Culex, Anopheles e Lutzomyia, vectors of the dengue and yellow fever, West Nile virus, Malaria and Leishmaniasis respectively. The "MONITORING AND CONTROLLING SYSTEM OF ENDEMIC DISEASES AND TRAP WITH OVIPOSITIONAL SYNTHETIC ATTRACTANTS TO CAPTURE MOSQUITOES" (10) can be used both for endemic disease monitor purposes that are necessary for the Public Health management and for defensive purposes when it is applied for catching the hematophagus pregnant females of the mosquitoes that transmit the pointed out diseases in household, commercial, industrial or public settings.
