Disease Transmission
Disease transmission refers to the process by which infectious agents, such as bacteria, viruses, parasites, or fungi, are spread from one person to another, or from animals to humans. This can occur through direct contact, such as touching or kissing, indirect contact, such as touching a contaminated surface, or through the air, such as when an infected person coughs or sneezes. Disease transmission can also occur through contaminated food or water, or through vectors such as mosquitoes or ticks. Understanding how diseases are transmitted is crucial for preventing and controlling outbreaks.
