Question:
1.Why is global action required to deal with health issues?
Epidemics don't stop at national borders.
Fill in the blanks:
Animals such as birds and pigscarry viruses thatmay mutate into a strain thatcan infect humans. Such a new straincould lead to another pandemic well before a newvaccine could be developed.
