The number of confirmations in wild birds rises to 5
The Ministry of Agriculture and Livestock (Mapa) informs that it has intensified surveillance actions in populations of domestic and wild birds throughout the country. Last Saturday (May 20), the Federal Laboratory for Agricultural Defense of São Paulo (LFDA-SP), a reference unit of the World Organization for Animal Health (OIE), confirmed two more cases of Highly Pathogenic Avian Influenza (HPAI) of the H5N1 subtype . With this, the number of confirmed cases in wild birds rises to 5, but none in humans.
The state of Espírito Santo accounts for yet another confirmed case in a wild bird, this time of the Thalasseus Maximus species (popular name of the royal tern). The animal was found in the rural area of the municipality of Nova Venécia. As the occurrence was in a non-coastal area, the surveillance action will also be extended to neighboring municipalities: São Gabriel da Palha and Águia Branca.
The other case, also in a wild bird, was detected in the state of Rio de Janeiro, in São João da Barra, in a coastal area. It is a bird of the species Thalasseus acuflavidus (popular name Trinta-réis-de-bando).
Suspect human cases in Espírito Santo
The Ministry of Health was notified, this Saturday morning (May 20), about the negative result for avian flu in all employees of Parque da Fazendinha, in Espírito Santo, where a sick bird was found. Of the 33 employees, only one was under observation as a suspected case of the disease, as he had flu-like symptoms during the week. The result released today informs that the suspected case had a negative laboratory result for all targets tested – that is, it was discarded for Avian Influenza (H5N1). Of the other 32 samples, 30 were negative for all targets tested and 2 tested positive for viruses that were already in circulation (Influenza A and Influenza B).
Of the total, in addition to the suspected case discarded in Parque Fazendinha, three other symptomatic patients were reported in the state, one of which has already been discarded. The other two had samples collected and are awaiting results. According to the surveillance protocol, the patients were isolated and monitored by the health teams.
The samples were analyzed by the Fiocruz laboratory, in Rio de Janeiro, after referral from the Central Public Health Laboratory (Lacen) in Espírito Santo. The Ministry of Health guided an active search for the investigation of all people who had contact with the animals.
