The CDC states that the risk to the general public from these viruses remains low, with only four mild-to-moderate cases reported in the US.

Dr. Jennifer Brull, president of AAFP, notes that the main sources of exposure are dairy cattle and poultry farms.

While bird flu is primarily spread from bird to bird, humans can contract it through close contact with infected birds, bird droppings, contaminated water, or surfaces.

Symptoms can appear 2 days to a week after exposure and may include fever, cough, sore throat, and more severe respiratory issues.

If you suspect bird flu, contact your physician for confirmation or ruling out the disease.
