Canadian health officials warn of H5N1 bird flu and rising measles cases in 2025.

Canada's top health official warns of H5N1 bird flu and measles as major 2025 concerns. H5N1 has caused the first human case in Canada since its return to the country and has spread to 65 people in the U.S., mostly farm workers. Measles cases in Canada have nearly doubled to 170 in 2024 from 59 in 2023, mostly affecting the unvaccinated. The U.S. struggles to control the bird flu outbreak among cattle, affecting over 875 herds in 16 states, due to issues like industry deference and budget cuts. The virus poses a pandemic risk if it mutates for human-to-human transmission.
