. cholerae can enter the body in contaminated food or water. The bacteria breed in the small intestine, where they secrete a toxin that reduces the ability of the epithelium of the intestine to absorb salts and water into the blood. These are lost in the faeces, causing diarrhoea. If not treated, the loss of fluid can be fatal. Cholera is most likely to occur where people use water or food that has been in contact with untreated sewage, as the bacteria are present in the faeces of an infected person.
M. tuberculosis can enter the lungs in airborne droplets of liquid that are breathed in. This is more likely to happen in places where many people are living in crowded conditions.
AIDS is caused by the human immunodeficiency virus, HIV. This is a retrovirus, which contains RNA. The virus enters T-lymphocytes, where its RNA is used to make viral DNA which is incorporated into the T-lymphocytes' chromosomes. Usually nothing more happens for several years, but eventually multiple copies of the virus are made inside the T-lymphocytes, which are destroyed as the viruses break out and infect more cells. Eventually there are so few functioning T-lymphocytes that the person is no longer able to resist infection by other pathogens and develops one or more opportunistic diseases such as TB.
Transmission occurs through the inhalation of droplets of moisture containing the virus. It is highly infectious, so that a high proportion of people who come into close contact with an infected person will also get the disease.

HEY!!
✴AIDS
✔AIDS is Acquired immune deficiency syndrome. AIDS is caused by a virus called HIV(Human immunodeficiency virus).When this virus enters the blood streams, a person may become infected with it & said to be HIV positive.
✴MEASLES
✔Measles is a highly contagious respiratory infection that is caused by rubeola virus. It causes skin rashes and flu-like symptoms, including a fever, cough, and runny nose. The infection is transmitted by droplets. There is no specific treatment for measles but it can be prevented by vaccination.
✴TUBERCULOSIS
✔Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections do not have symptoms, known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those infected.
✴HONG KONG FLU
✔The Hong Kong flu is an especially infectious strain of the virus. It has the ability to mutate both during and between flu seasons (more so than other strains), rendering our preventative vaccines less effective.
✴CHOLERA
✔Cholera is caused by bacteria Vibrio cholerae. It is transmitted by contaminated water. The stools and vomit of the cholera patient are full of these bacteria and these are transmitted into a healthy person when contaminated food or drink is taken by mouth. Treatment includes rapid replacement of fluid and electrolytes by oral rehydration therapy.
