Several factors contribute to the emergence of viral infections:
Zoonotic Spillover: Many emerging viruses originate in animals and are transmitted to humans. Global Travel: Increased international travel can facilitate the rapid spread of viruses. Urbanization: Expanding urban areas can increase human exposure to wildlife and vectors. Climate Change: Changes in climate can alter the distribution of vectors like mosquitoes, enabling the spread of viruses to new areas. Deforestation: Habitat destruction can bring humans into closer contact with wildlife reservoirs of viruses.
