Spread of tuberculosis

It is a known fact that the disease spreads when an infected individual sneezes, coughs, speaks or sings. The bacteria from the lungs or throat into the air are released where others easily inhale them. An individual can become infected by inhaling the tuberculosis bacterium.

Who are at risk?

Not all who are infected with tuberculosis becomes sick. Those who have a weakened immune system including those who have AIDS, infants and elderly could not fight the bacterium and prevent them from spreading to others.

As a communicable disease, proper hygienic measures should be observed at all times to prevent the spread of the condition. One way is to observe proper hand washing at all times.

Difference between latent and active tuberculosis

Tuberculosis that does not trigger sickness is called as latent tuberculosis. An individual with latent tuberculosis is not capable of spreading the disease to others. Once the individual becomes sick, he/she have active tuberculosis. Take note that latent tuberculosis can progress into the active form anytime especially when the immune system of the individual is preoccupied in fighting other illnesses such as flu or cold.

Treatment for tuberculosis

When treating tuberculosis, it typically includes oral medications that spans for 6-12 months. For latent tuberculosis, the doctor will prescribe isoniazid. As for active tuberculosis, the doctor will prescribe a combination of medications which includes rifampicin, isoniazid, pyrazinamide and ethambutol. In most cases, the doctor will prescribe different medications for nursing women, pregnant women, young children and those who have AIDS. In case drug resistance has developed in which medications could not eliminate the bacterium, the doctor will prescribe additional medications that are effective in dealing with the bacteria.

Prevalence of tuberculosis

It is important to note that the condition is considered one of the most infectious diseases. Anyone can easily acquire the disease but many do not develop active tuberculosis. Always bear in mind that the disease is present in all corners of the globe but more common in African and Southeast Asian countries.

Vaccination for tuberculosis

There is a vaccine for tuberculosis which is called BCG vaccine. Take note that the vaccine is not always effective and can pose certain health risks. The BCG vaccine is only recommended by healthcare professionals who work in areas where there is high risk for tuberculosis.
