The Adolfo Lutz Institute confirmed last week that three howler monkeys found dead in the State Park of Serra do Mar in Caraguatatuba were even victims of yellow fever. Six other animals are still under investigation. The information was passed on by the City Hall, which still recommends to close the park.
The proposal was already rejected on the 16th by the state government, which keeps the park open with the orientation that the visitor has to vaccinate for ten days on the spot. The State Department of Health reported that it also follows the strategies applied since that date, of intensifying vaccination.
According to Marcos Boulos, disease control coordinator of the secretariat, the continuity of the spread of the virus in the winter, after the outbreak of summer, was already expected. "Since last year São Paulo has become an area endemic to yellow fever and the epidemic is not coming and we assume that yellow fever has persisted, so we insist that all people are protected from the disease."
For Caraguatatuba, he says, dead monkeys were found in Ubatuba and in the Ribeira Valley in the winter.
Boulos rejected the need to close the park because of the high vaccination rate of the Caraguatatuba population, which is about 85%.
"It is different than at the end of the year in São Paulo." When the virus arrived in Horto, we did not have a protected population, it would only be 5% of the population. such as closing the entire park. What is needed is to warn the parks that everyone who arrives there must be vaccinated because they are at great risk if they go to the forest, to waterfalls, to get infected, "he explains.
About the risk of a new outbreak in the summer, when the circulation of the mosquito increases, Boulos said there is a "real chance". He recalls that vaccination coverage in Greater São Paulo, despite all campaigns, is only 40%.
"It is a fact that the virus keeps circulating and we have susceptible people, it may not be as severe as at the beginning of the year, but I'm not surprised to see a significant number of cases again in the summer."
According to the leaflet in 2018, 502 autochthonous cases of wild yellow fever were confirmed in the state, with 178 deaths. Most infections – 30.2% – occurred in Mairiporã and 9.5% in Atibaia. Another 14 cases occurred on the north coast, with 5 deaths – 2 in São Sebastião and 3 in Ubatuba.
The death of 250 monkeys has also been confirmed by the disease. The region with the highest concentration is Greater São Paulo, with 52% of the cases. 14 deaths were recorded in the north coast. Recent cases of Caraguatatuba have not yet been declared well.
