Tuberculosis Symptoms, Causes and Risk Factors
Tuberculosis (TB) is a serious infectious disease that commonly affects your lungs, a condition known as pulmonary TB. But, it can also affect other parts of the body, including the nervous system, glands and bones. TB is a bacterial infection spread through inhaling tiny droplets from the coughs and sneezes of an infected person. Symptoms of Tuberculosis are depending on which part of the body has been infected, that is which type of tuberculosis it is. So here we provide the information about Tuberculosis Symptoms, Causes and Risk Factors.
TB Diseases Causes, Symptoms and Risk Factors:-
There are mainly two Types of Tuberculosis (TB) conditions:
- Latent Tuberculosis (TB) Infection and
- Active Tuberculosis (TB) Diseases
Latent TB Infection:-
In this condition, you have Tuberculosis infection, but the bacteria are present in your body but are in an inactive state, neither making the person sick nor infecting others.
Active TB Diseases:
This condition makes you sick & may spread to others. It may occur in the 1st weeks after infection with the tuberculosis bacteria.
Sign and Symptoms of Tuberculosis:-
Some persons carry the TB bacteria but don’t experience signs. This condition is called latent TB. Latent TB may develop into active TB. Active TB causes many signs & symptoms. The bacteria that cause TB multiply extremely slowly, so the TB Symptoms also develop slowly, generally over months to years.
Symptoms of TB include:
- Appetite loss
- A persistent coughing that lasts three or more weeks
- Coughing up blood
- Chest pain or pain with coughing or breathing
- Weight loss
- Night sweats
Tuberculosis is caused by a bacterium known as Mycobacterium TB. But there are several of TB strains.
Bacteria are transmitted through the air, when an infected person coughs, sneezes, speaks or laughs. A nearby people can then inhale the TB bacteria.
Persons with strong immune system cannot experience Symptoms of TB, even though they carry the bacteria. This is called latent TB. Latent or Inactive TB is not contagious.
If the immune system fails to kill the infection, it may spread within the lungs or other parts of body & signs will develop within a few weeks or months. This is called active TB.
Tuberculosis Risks Factors:-
Anyone can get TB, but certain factors may increase your Risk of the TB diseases. The chances of getting infected by the TB infection are highest for persons that are in close contact with others who are infected. These factors include:
- Friends & family of a person with infectious TB
- People who have emigrated from areas of the world with highest rates of TB
- Persons in groups with high rates of tuberculosis transmission, including the homeless persons, persons living with HIV infection & injection drug users
- Persons who work in institutions or facilities that house persons who are at high risk for TB diseases like nursing homes, homeless shelters, residential homes, correctional facilities & hospitals for those with HIV
Not every person who is infected with the TB bacteria develops TB diseases. Persons at highest risk for developing active TB are those with a weak immune system, including:
- Persons with chronic conditions such as kidney diseases or diabetes
- Babies & young children with weak immune system
- Persons with HIV/AIDS
- Persons with receiving certain specialized treatments for autoimmune disorders like crohn’s diseases or rheumatoid arthritis
- Cancer patients undergoing chemotherapy
