that affect mostly other birds‚ but few can be transmitted to humans.

Majority of cases have been transmitted via bird-to-human‚ with rare cases of human-to-human transmission. Continued exposure to the virus not only poses the threat of ongoing morbidity and mortality‚ but also the threat of H5N1 being able to adapt
