Question

Quizplus · Accepted Answer

Influenza viruses capable of mutating into strains infective to humans are known to be harbored by both birds and swine. This is because these animals are capable of being infected with both avian and human influenza viruses, leading to the potential for reassortment and the creation of a new virus that can infect humans. Other animals may also harbor influenza viruses, but they may not be as likely to mutate in a way that allows them to infect humans.
