Tuberculosis most commonly affects the lungs. Symptoms include productive cough, fever, weight loss, and malaise. Diagnosis is most often by sputum smear and culture and, when available, by nucleic acid amplification tests. Treatment is with multiple antimicrobial drugs given for at least 4 months. (See also Perinatal Tuberculosis (TB) Tuberculosis can be acquired during the perinatal period. Symptoms and signs are nonspecific. Diagnosis is by culture and sometimes x-ray and biopsy. Treatment is with isoniazid and other antituberculous... read more and Extrapulmonary Tuberculosis (TB) Tuberculosis outside the lung usually results from hematogenous dissemination.

• Scrofuloderma can occur when TB spreads from infected • Tuberculous verrucosa cutis is characterized by the formation of large red plaques (lesions) larger than 1 centimeter (cm) in diameter. These lesions have a characteristic white or light-colored buildup and are typically found on the hands, fingers, and toes. • Lupus vulgaris is characterized by the development of a large, singular, and irregularly shaped lesion, shiny and brown, similar in appearance to applesauce. It typically affects the face and ears and can transform into an ulcer. • Tuberculous chancre: Also known as primary inoculation TB, this arises within two to four weeks of exposure as papules and nodules on the face, arms, or legs. These join to form painless lesions (patches of raised, pale, and discolored skin). Tuberculous chancre eventually spreads to the lymph nodes and the • Erythema induratum of Bazin (EIB): EIB causes the formation of painful, purple lesions on the legs. This condition tends to affect young and middle-aged women, with symptoms coming and going, often leaving scars. Without treatment, this condition can flare up every three to four months. • Papulonecrotic tuberculids: These are large lesions seen on the feet, legs, hands, arms, and buttocks, often accompanied by fever, fatigue, and loss of energy. The lesions develop a hardened, scabby crust and cause permanent scarring. • Tuberculous orificialis: Tuberculous orificialis is the development of large, irregular ulcers in the mouth...

Tuberculosis Symptoms Tuberculosis is a contagious infection that usually attacks the human respiratory system, especially the lungs. Overview of Tuberculosis Tuberculosis, also referred to as TB, is a contagious disease, but it cannot be spread easily as the bacteria cannot survive on exposed external surfaces. Any person who is in constant contact with an infected person has a high risk of contracting the disease. Therefore, co-workers, close family members, friends and anybody who is in proximity to the infected person is at a higher risk of being infected. Tuberculosis is a disease caused by the bacteria Mycobacterium tuberculosis – which can appear as either Gram-negative or Gram-positive bacteria of the genus of Actinobacteria. Apart from the lungs, these bacteria can attack and spread to other parts of the body, including the brain, spine and kidney. Here, let us learn more detail about the symptoms of this contagious disease-Tuberculosis. Also Refer: Symptoms of Tuberculosis Tuberculosis symptoms (TB symptoms) may not be immediately visible. This is because there are two forms of the disease- • Latent Tuberculosis • Active Tuberculosis As the name suggests, latent tuberculosis doesn’t make the person sick or contagious. Though the causative microbe is present within them, the infected individual does not show any symptoms. This is because their immune system stops the microbes from spreading, but doesn’t completely kill them. This creates a window of opportunity...

What is pulmonary tuberculosis? The bacterium Mycobacterium tuberculosis causes M. tuberculosis primarily attacks the lungs. However, it can spread from there to other organs. Pulmonary TB is curable with an early diagnosis and antibiotic treatment. Pulmonary TB, also known as consumption, spread widely as an epidemic during the 18th and 19th centuries in North America and Europe. After the discovery of antibiotics like streptomycin and especially isoniazid, along with improved living standards, doctors were better able to treat and control the spread of TB. Since that time, TB has been in decline in most industrialized nations. However, TB remains in the top 10 causes of death worldwide, according to the That said, it’s important to protect yourself against TB. Over 9.6 million people have an active form of the disease, according to the Being exposed to M. tuberculosis doesn’t necessarily mean you’ll get sick. Among the People with latent TB aren’t contagious and have no symptoms because their immune system is protecting them from getting sick. But it is possible for latent TB to develop into active TB. Most people with the germ have up to a If you’re at risk of being exposed to M. tuberculosis (for example, because you were born in a country where TB is common), you should talk to your doctor about being tested for latent TB infection and being treated if test results are positive. You can’t get pulmonary TB by: • shaking hands • sharing food or drink • sleeping in the s...

Some people who acquire Active TB typically causes many symptoms. While symptoms usually relate to the respiratory system, they could affect other parts of the body, depending on where the TB bacteria grow. Symptoms caused by TB in the • cough lasting more than 3 weeks • • chest pain General TB symptoms include: • unexplained • weakness • • • • • Along with general symptoms, TB that spreads to other organs can also cause: • • • nausea and vomiting, Risk factors that increase your chance of contracting the bacteria that causes TB disease include: • having • • using • a diagnosis of HIV or having another immune-system-compromising situation Medications that suppress the immune system can also put people at risk of developing active TB disease. These include medications that help prevent organ transplant rejection. Other medications that increase your risk of active TB include those taken to treat: • • • • • According to the Traveling to regions with high TB rates can also increase your risk of contracting the bacterial infection. These regions include: • sub-Saharan Africa • India • Mexico and other Latin American countries • China and many other Asian countries • parts of Russia and other countries of the former Soviet Union • islands of Southeast Asia • Micronesia Many lower-income U.S. households have limited access to resources, including healthcare, needed to diagnose and treat TB, which puts them at greater risk of developing active TB disease.

What Is Tuberculosis? Mycobacterium tuberculosis causes it. Can tuberculosis be cured? In the 20 th century, TB was a leading cause of death in the United States. Today, most cases are cured with Tuberculosis Types A TB infection doesn’t always mean you’ll get sick. There are two forms of the disease: • Latent TB. You have the germs in your body, but your • Active TB. The germs multiply and make you sick. You can spread the disease to others. Ninety percent of active cases in adults come from a latent TB infection. A latent or active TB infection can also be drug-resistant, meaning certain medications don’t work against the bacteria. Tuberculosis Signs and Symptoms Latent TB doesn’t have symptoms. A Signs of active TB disease include: • A • • • Feeling • • Chills • • Loss of appetite • If you have any of these symptoms, see your doctor to get tested. Get medical help right away if you have chest pain. Tuberculosis Causes Tuberculosis is caused by bacteria that spread through the air, just like a Tuberculosis Risk Factors You could be more likely to get TB if: • A friend, co-worker, or family member has active TB. • You live in or have traveled to an area where TB is common, like Russia, Africa, Eastern Europe, Asia, Latin America, and the Caribbean. • You’re part of a group in which TB is more likely to spread, or you work or live with someone who is. This includes homeless people, people who have HIV, people in jail or prison, and people who inject drugs into their veins....

• Tuberculosis is suspected. • You were likely exposed to a person with active TB disease. • You have health risks for active TB disease. Your provider will determine whether a skin test or blood test is the best option. Skin test A tiny amount of a substance called tuberculin is injected just below the skin on the inside of one forearm. Within 48 to 72 hours, a health care worker will check your arm for swelling at the injection site. The size of the raised skin is used to determine a positive or negative test. This test is seeing if your immune system reacts, or has made an antibody, to tuberculosis. A positive test indicates you likely have either a latent TB infection or active TB disease. People who had a TB vaccination might get a positive test even if they have no infection. A negative test means that your body didn't react to the test. It doesn't necessarily mean you don't have an infection. Blood tests A sample of blood is sent to a lab. One lab test finds out whether certain immune system cells can "recognize" tuberculosis. A positive test shows that you have either a latent TB infection or active TB disease. Other tests of the blood sample can help determine if you have active disease. A negative result means you likely do not have a TB infection. X-ray A chest X-ray can show irregular patches in the lungs that are typical of active TB disease. Sputum tests Your health care provider may take a sample of the mucus that comes up when you cough, also called sputum....
