Tuberculosis is a disease that is brought about by bacteria known as Mycobacterium Tuberculosis. If a person has TB in their lungs and coughs or sneezes, the TB bacteria are released into the atmosphere. If another person breathes the bacteria in, the following may occur
Someone having latent TB in their body system may not be sick at all and they do not have the capability to transmit the TB to other people. Whenever the bacteria wakes up in the body system causing the disease it becomes active TB. Latent Tb can be cured and can be treated to stop the condition from being active.
A person with latent TB does not have signs of the condition and they are healthy looking. At the same time, it is not possible to transmit TB to others.
Latent TB can only be identified to be present in the body system of a person by having a blood test or TB skin test done. The condition if detected can be cured by using one or two prescriptions over three to six months.
Precautions should be taken by TB patient to ensure that the spread of the disease is controlled, such as coughing etiquette. People who are not being treated for the disease should not cough openly, this helps in checking the bacteria released into the air. One should cover their mouths and noses with a tissue or handkerchief.
Airborne precautions can also be done to prevent the transmission of the bacteria which is airborne.
