Avian Flu: Human Impact and Understanding

The video discusses the impact of avian flu, which has killed over 100 million farm-raised birds in the U.S. since 2022. It highlights the first human death in the U.S. and the virus's spread across species, affecting nearly 500 bird species and 70 mammal species. The video explains the virus's potential to mutate and reassort, posing a risk of a pandemic. However, the current human cases are mild, and the virus has not yet shown efficient human-to-human transmission. The video emphasizes the importance of monitoring and preventive measures.

Why is the presence of avian flu in dairy cows concerning?

• It affects milk production

• It brings the virus closer to humans

• It causes respiratory issues in cows

• It leads to a new strain of flu

What are the two ways flu viruses can change?

• Mutation and reassortment

• Replication and adaptation

• Vaccination and immunity

• Transmission and infection

What is required for a virus to cause a pandemic?

• It must be airborne

• It must originate from animals

• It must be resistant to vaccines

• It must be novel and infect humans

What is the current nature of avian flu in humans?

Why is reassortment in humans less likely than in pigs or birds?

• Humans have less exposure to viruses

• Humans have stronger immune systems

• Humans have fewer virus strains

• Humans have different cell structures

What role do vaccines play in the current avian flu situation?

• They offer slight protection from previous exposure
