Answer 1

Answer:

1.Rabies is a viral illness spread via the saliva of an infected animal by therabies virus (genus Lyssavirus). Rabiesexposure occurs usually through biting a human or another infected animal.Transmission can also occur through saliva touching an open wound or touching mucous membranes.

2.The bacteria are transmitted between humans through the fecal-oral route; a bite of contaminated food or a sip of contaminated water can causeinfection. More specifically, a toxin secreted by the bacteria, which targets receptors in the human intestine, is responsible for the pathology characteristic of the disease.

3.Malaria spreads when a mosquito becomes infected with the disease after biting an infected person, and the infected mosquito then bites a noninfected person. The malariaparasites enter that person's bloodstream and travel to the liver. When the parasites mature, they leave the liver and infect red blood cells.

4.TB bacteria are spread through the air from one person to another. The TBbacteria are put into the air when a person with TB disease of the lungs or throat coughs, speaks, or sings. People nearby may breathe in these bacteria and become infected.
