Successful NTD Project in Recife, Brazil Gains Recognition for Preventing and Controlling NTDs in Children

 

By Dr. Mirta Roses Periago, NTD Special Envoy 

As NTD Special Envoy to the Global Network, I am delighted to share with you a great story: the neglected tropical disease (NTD) project in Recife, Brazil won the award for best work experience in surveillance, prevention and integrated control of NTDs, including leprosy, leishmaniasis and other communicable diseases related to poverty, during the 13th EXPOEPI held in October 2013 in Brasília. The NTD project in Recife is a joint effort between the local governments and the Inter-American Development Bank (IDB), the Pan American Health Organization (PAHO) and the Global Network for Neglected Tropical Diseases of the Sabin Vaccine Institute.

Organized by the Secretariat of Health Surveillance of the Brazilian Ministry of Health, the National Exhibition of Successful Experiences in Epidemiology, Prevention and Diseases Control (EXPOEPI) brings together managers and technicians in public health from all the federative units to discuss relevant matters in their field and share experiences with one another.  Around 3,000 people participated at this year’s event. Dr. Jarbas Barbosa, Secretary of Health Surveillance of Brazil, said that the importance of this event comes from the motivation and belief that planned actions that are properly implemented, monitored and evaluated can make a very positive difference in  the health of the Brazilian population.

The award specifically recognized the success of the NTD project in the Recife metropolitan area  in preventing  and controlling  communicable diseases through  building integrated teaching tools to motivate the teaching-learning processes of students. Because of this project, 16 thousand students are learning about NTDs and, most importantly, about how to treat and prevent infection. The program is being implemented in three cities in the Pernambuco state (Recife, Olinda, and Jaboatão dos Guararapes) by the local health departments and the Institute of Integral Medicine Professor Fernando Figueria (IMIP). It addresses four NTDs present in the metropolitan area (leprosy, lymphatic filariasis, soil-transmitted helminths, and schistosomiasis) through education, diagnosis, treatment, and prevention activities.

Forty-two public schools in the Recife metropolitan area are implementing the program, indirectly benefiting an additional 70 thousand family members because of the health education and prevention activities, as well as the medical assistance, diagnosis and treatment of the diseases. Additionally, encouraged in large part by the positive results of the project, the Ministry of Health of Brazil conducted a nation-wide campaign to address leprosy and intestinal parasites in March 2013.

We invite you to watch the video “A Small Revolution: A Comprehensive Approach for Neglected Tropical Diseases” to learn more about how the education components were integrated into the school system, to improve the health of the communities of the Recife metropolitan area. You can also view photos of the community social mobilization here.

You can also watch the video “” to see some of the educational videos that were produced for the NTD project in Recife, in collaboration with the Mediateam Company.

I encourage you to share your stories with us, as well as to feel inspired by our experiences and take action, sponsor or initiate similar activities so that we can together celebrate the end of NTDs in this generation.

Trinidad and Tobago. A Success Story in the Fight Against NTDs.

This Caribbean country has succeeded in controlling or eliminated most NTDs. Dr. Dave Chadee, Professor of Environmental Health at the University of the West Indies, shares his vision about this success story, and highlights ideas that can be applied in other countries where the Neglected Tropical Diseases Initiative for LAC is implementing several projects.

Dr. Chadee, what is the situation regarding NTDs in Trinidad and Tobago?

The situation regarding NTDs in my country is quite different from that of our neighbor’s. The country has eliminated lymphatic filariasis (LF) as well as malaria, and leprosy has been reduced to less than 1 case in every 100,000 inhabitants so it is no longer considered a major public health problem. We have also reduced the incidence of hookworms and recent surveys have not found cases of this infection. Today, the NTDs that are still considered a real challenge are yellow fever, which still persists in some pockets in forested areas (a zoonosis), and dengue, the most extensive  and problematic vector-borne disease in Trinidad and Tobago and the Caribbean region.

Dr. Dave Chadee

In your opinion, what are the main factors that have helped control and eliminate these diseases in the country?

Well, first of all the fact that Trinidad and Tobago has an universal, free to all health care system that has helped in controlling or eliminating most of the local and imported diseases. This is an advantage compared to other countries in the Caribbean region, because offering free treatments to all for any NTD makes it easier for people to seek help when they need it, no matter their ability to pay for these services and whether they are nationals or non nationals.

I also think that having staff that have received specific training on NTDs is key, and not only do they need to acquire the knowledge: they need to keep informed of new developments in their field by receiving updates or refresher training.

Another success story for the country involves the strategy against NTDs – which involves continuing monitoring and evaluation activities. We know of programs that have implemented wonderful strategies but did not incorporate internal audits to check their effectiveness, strengths and weaknesses over time, significantly reducing the efficacy of the programs.

Last but not least, I believe that the political support of local authorities is key, both for the implementation of effective programs and to keep morale high among health workers. NTD work can be tedious because it is a battle that is never complete, so keeping the morale of the teams high, making workers feel appreciated, is very important.

What is the importance of vector management in the fight against NTDs?

Our experience has demonstrated that integrated vector management can help combat these diseases more effectively. At my university we have developed vector control strategies that are effective against Culex quinquefasciatus and other container breeding mosquitoes. Also, our research demonstrates that integrated vector management can be useful if used together with mass drug administration programs, and can help raise awareness about LF and other NTDs among communities.

Based on your latest research about transmission of LF, what are the changes you have observed in the habits of the Culex mosquito in the last years?

Based on my research, there is evidence that the blood feeding times of the Culex quinquefasciatus mosquito, the main vector for the transmission of LF, have shifted significantly. Previous studies showed the peak biting times in Trinidad and Tobago was between 10 pm and 3 am. Now we are finding a bimodal pattern with an early peak between 7 and 9 pm, as well as the 10-3am peak. This shift may be due to any of several factors like the use of air conditioning and fans in the household and the change of light regimens in cities such as the use of indoor lights and security lights from dusk to dawn. This means that the Culex mosquitoes  have access to people  between 7 and 11 pm, when they  are relaxing  at home and are likely to be casually dressed and  exposing larger skin surface area to foraging mosquitoes. In addition, our preliminary study shows more biting in areas around the legs and arms, thereby increasing the possibility of LF transmission at an earlier time during the night than previously thought. We think it is important to take these factors into account when designing programs to fight LF and other vector-born NTDs.
