Update on Avian Influenza A(H5N1) “Bird Flu”  CDC continues to respond to an H5N1 bird flu outbreak in poultry and dairy cows in the United States. On September 27, CDC shared an update on the state-led investigation in Missouri: While some health care workers were retrospectively detected as contacts of the H5N1 bird flu case; no additional cases in that state have been detected and no person-to-person spread has been observed. CDC issued updated personal protective equipment guidance (PPE) to prevent H5N1 bird flu infection.  Learn More

Record Number of Flu Deaths in Children Reported for 2023-2024 CDC reported a new flu-related death in a child, raising the total deaths to 200 for the 2023-2024 season. This surpasses the previous high of 199 flu-related deaths in children during a regular flu season set during 2019-2020. About 80 percent of children who were eligible for flu vaccination and for whom vaccination status was known were not fully vaccinated against flu.                                                                       Learn More

It found no increased risk of negative health outcomes for mom or baby among pregnant people who got flu vaccines during successive pregnancies. That was true regardless of how far apart the pregnancies were spaced.  Learn More
