True or False: Only certain strains of avian influenza are considered a threat.

1. True

2. False

3. It's a seasonal illness

4. It only spreads through wild birds

The correct answer is: True

The statement that only certain strains of avian influenza are considered a threat is accurate. Avian influenza viruses are categorized into low pathogenic avian influenza (LPAI) and highly pathogenic avian influenza (HPAI). While many strains of avian influenza circulate naturally in wild birds without causing serious disease, certain strains, particularly those classified as HPAI, pose significant risks to both avian species and, in some cases, can infect humans and other animals. HPAI strains can lead to severe illness and high mortality rates in domestic poultry populations, leading to significant economic loss and public health concerns. These strains are often closely monitored and controlled through biosecurity measures, as their potential for rapid spread and serious impact is much greater than that of LPAI strains. The other options presented do not accurately represent the situation regarding avian influenza. It is not a seasonal illness, as it can occur year-round, and while wild birds are known to harbor and spread the virus, avian influenza can also spread through domestic poultry and other animals. Thus, recognizing the selective threat of specific avian influenza strains is crucial in managing and mitigating risks associated with this virus.
