Question

Which of these diseases can spread due to the coughing of the patient?
A. AIDS, T.B. and hepatitis
B. T.B., influenza and cholera
C. T.B. and influenza
D. T.B. and hepatitis

Answer 1

Common spread of infectious diseases is through the direct transfer of bacteria, viruses or other germs from one person to another. This spread can happen when an individual infected with the bacterium or virus touches, kisses, coughs or sneezes on someone who is not infected. Infectious disease can also spread through exchange of body fluids from sexual contact.

Complete answer:
Option A AIDS, T.B. and hepatitis: The HIV virus causes AIDS and interferes with the body's ability to fight against infections. This virus can be transmitted through the contact of infected blood, semen or vaginal fluids. Bacteria which cause tuberculosis are spread when an infected person coughs or sneezes. The hepatitis A virus is primarily transmitted through faecal-oral route. Here, AIDS and hepatitis are not spread through cough.
Hence option A is not correct.
Option B T.B., influenza and cholera: Bacteria which causes tuberculosis are spread through tiny droplets released into the air from person to person via coughs and sneezes. Influenza can spread to others for up to about 6 feet away. The flu viruses mainly spread through droplets made when people with flu cough, sneeze or talk. By drinking water or eating food contaminated with cholera bacteria, a person can get infected with cholera. Here, cholera is not spread through cough.
Hence option B is not correct.
Option C T.B and influenza: Bacteria causing tuberculosis are spread from person to person through tiny droplets which are released into the air via coughs and sneezes. People with influenza can spread the disease to others that are about $6$ feets away. The influenza viruses spread mainly through droplets released when people with flu cough, sneeze or talk. Both T.B and influenza can spread through cough.
Hence option C is the correct answer.
Option D T.B and hepatitis: When a person with active tuberculosis disease in their lung’s coughs or sneezes and someone nearby inhales the expelled droplets, tuberculosis can be spread. The expelled droplets will have TB bacteria in it. Hepatitis usually spreads through food or water. Since hepatitis does not spread through cough.
So, option D is not correct.

Therefore, Option C) T.B and influenza is the correct answer.

Note:
The disease-causing organisms also can be passed on to others by indirect contact. Many germs can stick on to inanimate objects, such as a tabletop, doorknob or the handles of faucets. Many of the disease-causing germs or microorganisms can also be infected through contaminated food and water. This mechanism of transmission allows the germs or microorganisms to be spread to many people through a single source.
