PHILIPSBURG (DCOMM):---Tuberculosis (TB) is one of the top 10 causes of death worldwide. In 2017, 10 million people fell ill with TB, and 1.6 million died from the disease (including 0.3 million among people with HIV).
TB is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. Tuberculosis is curable and preventable. TB mostly affects adults, however, all age groups are at risk.
On Sunday, March 24, marked World Tuberculosis Day under the theme, “It’s Time for Action. End TB.”
The Ministry of Public Health, Social Development and Labour (Ministry VSA) Collective Prevention Services (CPS), a department within the ministry, says according to the Pan American Health Organization (PAHO), World TB Day is commemorated annually to raise public awareness about the consequences of TB for those who suffer from this preventable and curable disease and to step up efforts to end the global TB epidemic.
TB is spread from person to person through the air. When people with lung TB cough, sneeze or spit, they propel the TB germs into the air. A person needs to inhale only a few of these germs to become infected.
About one-third of the world's population has latent TB, which means people have been infected by TB bacteria but are not (yet) ill with the disease and cannot transmit the disease.
People infected with TB bacteria have a 10% lifetime risk of falling ill with TB. However, persons with compromised immune systems, such as people living with HIV, malnutrition or diabetes, or people who use tobacco, have a much higher risk of falling ill.
When a person develops active TB disease, the symptoms (such as cough, fever, night sweats, or weight loss) may be mild for many months. This can lead to delays in seeking care, and results in transmission of the bacteria to others.
People with active TB can infect 10–15 other people through close contact over the course of a year. Without proper treatment, 45% of HIV-negative people with TB on average and nearly all HIV-positive people with TB will die. TB is a leading killer of HIV-positive people.
