Tuberculosis is a chronic recurrent notifiable infection, most commonly occurring in the lungs, caused by Mycobacterium tuberculosis. Transmission is usually by inhalation of bacilli in airborne droplets.
The airborne particles then get inhaled and enter the exposed person’s lungs, where they multiply. Although TB is rare and highly treatable, you will still need to take measures to prevent tuberculosis in certain situations, especially if you have already tested positive for latent TB.
And as the old saying goes, an ounce of prevention is worth a pound of cure. In other words, the best way to be well is to avoid getting sick in the first place.
How can tuberculosis be prevented?
Avoid exposing yourself to people with active TB
Obviously the most important precaution you can take to prevent TB is to avoid being around people with active TB, which is highly contagious. In particular, it is important to avoid spending time with TB patients in warm, stuffy rooms.
You can help someone to get rid of the disease and lessen your own risk of contracting it by ensuring that they strictly follow treatment instructions. Moreover, if you work in a hospital where TB is currently being treated, you will need to take protective measures, such as wearing a face mask, to avoid breathing in the TB bacteria.
Practice good healthy lifestyles
People with low immune system are more susceptible to the TB virus, as their disease resistance is lower than in healthy people. Therefore, it is important to do your best to lead a healthy lifestyle. Eat a well balanced diet with plenty fruits, vegetables, whole grains and lean meat.
Avoid fatty, sugary and processed foods. Also, exercise often, at least 3 to 4 times a week. Practice good cardiovascular exercises such as running, swimming. Reduce intake of alcohol and avoid smoking or smoking hard drugs. Get enough quality sleep, ideally between 6 and 8 hours a night as well maintain a good personal hygiene.
Get the BCG vaccination to prevent TB.
