World Tuberculosis Day: How can TB be prevented!

New Delhi: Tuberculosis (TB) is a serious infectious disease caused by bacteria called Mycobacterium tuberculosis, mainly affects the lungs.

TB is spread from one person to another through tiny droplets released into the air via coughs and sneezes.

Anyone can get TB, but there are certain factors that increase one's risk of getting the disease such as:


People with weakened immune system due to 

HIV/AIDS, cancers, diabetes, severe kidney disease
Babies and young children
Elderly people
IV drug users
People who live with or care for someone with active TB
Health care workers who treat people with a high risk of TB
But TB transmission can be prevented through adequate ventilation and limited contact with patients.

Here are some basic tips to prevent getting TB or avoid spreading the disease to others:

Avoid direct contact with people with active TB, especially if you already have tested positive for latent TB
Know if you are at risk
Eat a healthy, balanced diet with lots of fruits and vegetables, whole grains, lean meat
Excercise for at least 3-4 times a week, if not daily
Avoid or cut down on alcohol intake
Do not smoke and if you do, quit it immediately
Get adequate sleep – at least 7-8 hours
Practice good personal hygiene – avoid coughing, sneezing directly at others.
Use protective measures such as wearing a face mask if you are caring for people who have untreated TB
Get the BCG (Bacille Calmette-Guerin) vaccination, however the vaccine is not commonly used in the US, where infection rates are low and the disease is highly treatable
Get early diagnosis and treatment in order to prevent deterioration of the disease and spread of the infection
If you are infected with TB, protect yourself while ensuring that you don't spread your germs to others.

Cover your mouth with a tissue when you laugh, cough or sneeze – remember to discard the used tissues in a plastic bag, seal and throw it away
Wash your hands asfter coughing or sneezing
Avoid close contact with others
Avoid going to work, school or sleep in a room with other people during the first few weeks of treatment for active TB
Ventilate your room often as TB spreads in small closed spaces
