Communicable diseases:
a. Tuberculosis
- is a common, and in many cases lethal, infectious disease caused by various strains ofmycobacteria, usually Mycobacterium tuberculosis. It typically attacks the lungs, but can also affect other parts of the body. - It is spread through the air when people who have an active TB infection cough, sneeze, or otherwise transmit their saliva through the air.  -Most infections are symptomatic and latent, but about one in ten latent infections eventually progresses to active disease which, if left untreated, kills more than 50% of those so infected. What causes tuberculosis?

Tuberculosis is ultimately caused by the Mycobacterium tuberculosis that is spread from person to person through airborne particles. It is not guaranteed, though, that you will become infected with TB if you inhale the infected particles. Some people have strong enough immune systems that quickly destroy the bacteria once they enter the body. Others will develop latent TB infection and will carry the bacteria but will not be contagious and will not present symptoms. Still others will become immediately sick and will also be contagious.

What are the symptoms of tuberculosis?
Most people who become infected with the bacteria that cause tuberculosis actually do not present symptoms of the disease. However, when symptoms are present, they include unexplained weight loss, tiredness, fatigue, shortness of breath, fever, night sweats, chills, and a loss of appetite. Symptoms specific to the lungs include coughing that lasts for 3 or more weeks, coughing up blood, chest pain, and pain with breathing or coughing. Prevention:

Protect your family and friends
-If you have active TB, keep your germs to yourself. It generally takes a few weeks of treatment with TB medications before you're not contagious anymore. Follow these tips to help keep your friends and family from getting sick: * Stay home. Don't go to work or school or sleep in a room with other people during the first few weeks of treatment for active tuberculosis. * Ventilate the room. Tuberculosis germs spread more easily in small closed spaces where air doesn't move. If it's not too cold outdoors, open the windows and use a fan to blow indoor air outside. * Cover your mouth. Use a tissue to cover your mouth anytime you laugh, sneeze or cough. Put the dirty tissue in a bag, seal it and throw it away. * Wear a mask. Wearing a surgical mask when you're around other people during the first three weeks of treatment may help lessen the risk of transmission.

b. Cholera

- Cholera is an infection in the small intestine caused by the bacterium Vibrio cholerae. The main symptoms are profuse, watery diarrhea and vomiting. Transmission occurs primarily by drinking water or eating food that has been contaminated by the feces (waste product) of an infected person, including one with no apparent symptoms.

What are the causes of Cholera?
Cholera is a diarrheal illness caused by the bacteria Vibrio cholerae. This species is not endemic to humans, and its presence in the human digestive system is not part of the natural life cycle of the bacteria. Normally found in an estuary ecology, the Vibrio cholerae bacteria life cycle naturally shifts between various reservoir species such as small snails and crustaceans, free-floating planktonic forms and static forms resident in the silt and muck of the estuary. 

Vibrio cholera bacteria enter the human ecosystem through a variety of routes. The most common entry is through contaminated food or water. When humans eat seafood--in particular shellfish native to estuary environments such as oysters or crabs--and fail to cook them completely or even eat them raw, they can ingest the large amounts of bacteria necessary to cause a case of cholera. ...
