Avaliação do cenário de introdução da Influenza Aviária de Alta Patogenicidade (IAAP) no Brasil

Abstract

Avian influenza is an infectious disease caused by a virus that primarily affects birds, but which can also infect humans and other animals. There are different types of avian influenza viruses, specifically the H5N1 virus, which is considered highly pathogenic, causes severe clinical symptoms in birds and is characterized by high mortality. Its trajectory is somewhat complex due to the existence of several subtypes and strains present in different countries over the months, where it may have originated in aquatic birds and, through direct or indirect contact, may have been transmitted to domestic birds. Secondary data collection and analysis were carried out, taken from public databases, such as the Ministry of Agriculture and Livestock (MAPA), World Organization for Animal Health (WOAH) and World Health Organization (WHO). Occurrences in Brazil were investigated, with emphasis on the state of Paraná, focusing on geographic distribution, migratory routes of wild birds and control measures implemented in Brazil and worldwide. To prevent dissemination, biosafety measures were adopted for poultry production, hence the importance of health surveillance and reporting of cases so that it is possible to control the spread and eradicate outbreaks of Highly Pathogenic Avian Influenza (HPAI), in addition to understanding the relationship between Avian Influenza outbreaks and bird migration. It is concluded that the global database is an important tool for monitoring the disease and early detection and control of the spread of the virus, contributing to minimizing the risks impacts on poultry production.
