Causes of TB … Get to know them

Tuberculosis is an infectious disease caused by a bacterium called tuberculosis bacillus. One-third of the world's population is infected with tuberculosis. Every year, about 9 million people are infected with the disease and about 2 million people die.

Tuberculosis: how is it transmitted?

The infection is transmitted when a person with an active infection with tuberculosis in the lungs sneezes or coughs in front of a healthy person. In this way, the bacteria released by the patient's mouth fall into the diffuse spray, while the healthy person inhales them.
The disease affects people who are generally poorly immunized compared to people with healthy and strong immune systems.

Causes of TB: Risk Factors

Risk factors associated with tuberculosis include:
People living in high TB ​​prevalence environments.
• People who work in the care of or live near a person infected with infectious tuberculosis. These include people who care for people with TB and people living in confined spaces with people with TB. School children and prisoners living in confined spaces are also more exposed.
• Travelers to places with a high incidence of tuberculosis. Migrants from TB countries may also carry bacteria in countries where there is no infection.
• People with other infections, such as AIDS, are less able to fight against tuberculosis infection. This is mainly due to the fact that the immune system has deteriorated due to infection with AIDS. People with certain conditions such as diabetes, immune problems, kidney failure, gastrectomy, those who take corticosteroids for a long time and who undergo cancer chemotherapy and other immunosuppressive treatments (such as drugs used after transplantation) are at risk. all a risk of tuberculosis.
Incomplete immune systems, for example in infants, and those with low immunity, such as the elderly, are more likely to develop TB. Pregnant women are also at increased risk of decreased immunity.
• Malnutrition that accompanies the general poor health of a person or those who have a poor diet, and addicts and alcoholics, who live in poverty and in homeless areas, are at higher risk of tuberculosis .
