It is said that diseases are spreading faster due to globalization and increased movement of people. Justify the statement taking the example of the $H_5N_1$ virus.

(N/A) Globalization and increased human mobility have significantly accelerated the spread of infectious diseases across international borders.
In the case of the $H_5N_1$ virus (Avian Influenza),the rapid movement of migratory birds and the global trade of poultry products facilitate the transmission of the virus to new geographical regions.
Once the virus enters a human population,the high frequency of international travel allows it to spread rapidly from one country to another.
If the virus develops the ability to transmit efficiently from human to human,the global connectivity of modern society ensures that it can reach pandemic proportions in a very short time.
