The US Centers for Disease Control and Prevention says it will test a sample from a 42-year-old woman who is believed to have died of a swine flu infection in Brazil in May.
When it receives the sample, the agency says, it plans to look for possible mutations that may have made the virus more contagious or more dangerous. According to the CDC, testing by a Brazilian health agency showed that the virus is genetically linked to previously detected swine flu infections in people in Brazil from 2020 to 2022. “CDC’s top priority is to confirm that the patient was infected with an influenza Av virus,” CDC spokesperson Kathleen Conley told CNN in a statement.
” The World Health Organization reports that the woman who died this year had two close contacts who worked at a swine farm near her home, but neither of the contacts tested positive for the virus. “Based on the information currently available, WHO considers this a sporadic case, and there is no evidence of person-to-person transmission of this event.
