Question
An infectious disease is ___________ .a.caused only by bacteria b.spread from person to personc.spread from animal to animal d.caused only by viruses
Solution
An infectious disease is b. spread from person to person.
Infectious diseases are caused by microorganisms such as bacteria, viruses, fungi, or parasites. They can be spread directly or indirectly from person to person. They can also be spread from animals to humans, or from the environment or external media. Therefore, while bacteria and viruses can cause infectious diseases, they are not the only causes. Similarly, while infectious diseases can be spread from animal to animal, this is not the only method of transmission.
