The human body, animals, and insects are considered reservoirs for disease transmission. This means that they can harbor and spread disease-causing organisms, such as bacteria, viruses, and parasites, to other individuals. For example, a person infected with a virus can spread it to others through coughing and sneezing, while an animal or insect carrying a parasite can transmit it to humans through bites or contact with bodily fluids. Controlling the spread of diseases from these reservoirs is important in preventing outbreaks and epidemics.
