Tuberculosis is spread from person to person via droplets in the air from coughing or sneezing. On rare occasions, it is spread via contaminated milk in the tropics.
Once an individual is infected they can remain without symptoms or go on to experience weight loss and general ill health. Tuberculosis most commonly affects the lungs and is accompanied by persistent coughing, blood stained sputum (phlegm), chest pain and fever.
Who is at risk of Tuberculosis?
Tuberculosis is found all over the world with China and India having the highest number of cases and Africa having the most deaths. In the UK, there has been a 25% increase in cases in the last ten years mainly among those from Asian backgrounds.
TB can only be caught from someone who already has the disease.
In the UK, routine vaccination of all school children is no longer practiced (DOH July 2005). A new vaccination programme now targets those children and adults at highest risk to the disease.
For those travelling to high-risk areas, such as Africa, Southeast Asia and parts of South America, proof of immunity is recommended.
How can I prevent Tuberculosis?
Partial protection is gained through BCG vaccination. The vaccination is only given at the presentation of a negative mantoux or heaf test. Only newborn babies are vaccinated without the test.
It is essential for all travellers going overseas to have a test and the subsequent vaccination if required. It is possible that immunity after vaccination is not lifelong and therefore all persons moving abroad to work in risk areas should consider testing, especially if the vaccination scar is not present. For advice regarding BCG, you should make an appointment with your family doctor or Travel clinic nurse.
For those with TB, treatment involves a variety of antibiotics taken over a period of months. The treatment will cure the disease ONLY if the treatment is continued until the end of the course. Because many people feel better, they stop taking the medication and this results in a recurrence of the disease.
