Most infections do not have symptoms, in which case it is known as latent tuberculosis. The classic symptoms of active TB are a chronic cough with blood-containing sputum , fever , night sweats , and weight loss. The number of new cases each year has decreased since Multiple variants may be present simultaneously. Tuberculosis may infect any part of the body, but most commonly occurs in the lungs known as pulmonary tuberculosis. The upper lung lobes are more frequently affected by tuberculosis than the lower ones. Spread to lymph nodes is the most common. In nature, the bacterium can grow only within the cells of a host organism, but M. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus.
Is Tuberculosis Contagious?
Fourteen of those who contracted the disease are from the elderly Hmong community, with 10 of those cases believed to have spread through shared activities at a senior center. Of the six deaths, three have been a direct result of tuberculosis or TB. Though TB is treatable with antibiotics, this particular strain is more difficult to fight because it is multi-drug resistant. Antibiotic-resistant bacteria is a growing concern in the US as it sickens more than two million Americans each year and causes about 23, deaths, according to the Center for Disease Control.
Tuberculosis TB is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.
Tuberculosis (Mycobacterium tuberculosis), also known as TB, is a disease spread by respiratory inhalation of droplets that contain the bacteria. Tuberculosis is an ancient disease that has been traced back at least years.

Legal situation[ edit ] In many English-speaking countries and in most of the states who have signed the European Convention of Human Rights ,  knowingly infecting others with HIV can lead to criminal prosecution. Under section 79 3 it is a defence, if the court is satisfied, that the defendant took reasonable precautions to prevent the transmission. If talking about the problems of practising safe sex does not help, the doctor may obtain a Public Health Order to manage the behaviour of the HIV positive person.
In NSW the relevant offences are separated into those done intentionally Section 33 of the Crimes Act ,  and those done recklessly Section The definition of grievous bodily harm GBH  now[ when? Under section 33 a person who intends to inflect grievous bodily harm on another person can be imprisoned for up to 25 years while under section 35 a person who recklessly causes another person grievous bodily harm can be imprisoned for up to 10 years and 14 years if in company.

Origins[ edit ] Scientific work investigating the evolutionary origins of the Mycobacterium tuberculosis complex has concluded that the most recent common ancestor of the complex was a human-specific pathogen , which underwent a population bottleneck. Analysis of mycobacterial interspersed repetitive units has allowed dating of the bottleneck to approximately 40, years ago, which corresponds to the period subsequent to the expansion of Homo sapiens sapiens out of Africa.
This analysis of mycobacterial interspersed repetitive units also dated the Mycobacterium bovis lineage as dispersing approximately 6, years ago, which may be linked to animal domestication and early farming. There have also been a claim of evidence of lesions characteristic of tuberculosis in a , years old Homo erectus fossile, although this finding is controversial.
Scientists were able to recreate the genome of the bacteria from remains of 1, year-old skeletons in southern Peru. In dating the DNA, they found it was less than 6, years old. They also found it related most closely to a tuberculosis strain in seals, and have theorized that these animals were the mode of transmission from Africa to South America.

Tuberculosis is a potentially serious infection caused by Mycobacterium tuberculosis bacteria that are spread mainly through the air from one person to another. TB usually infects the lungs, but can also cause symptoms that affect the whole body.
But there were other problems in the proclamation that AIDS antiretrovirals extended lives an average of 15 years. And they soon became apparent. While the original AIDS patients were desperately ill, many of them showing fowl tuberculosis early in their disease, presumably through rectal transmission………. Such AIDS individuals would survive longer. And then there was the terrible toxicities of these antiretrovirals. The fact that certain studies claim that antiretrovirals extend the life of an AIDS patient does not mean that they are benign in the least.
As just one example, and putting aside the black box warnings regarding liver failure, kidney failure and severe neuropathy — many cardiac complications of HIV are not affected by antiretroviral cocktails [HAART] and such heart problems continue to develop in AIDS either with antiretroviral treatment, or because of antiretroviral treatment. This is because viral treatment itself can cause a metabolic syndrome, characterized by altered body-fat distribution and an insulin resistance.
This together with other factors that such retroviral cocktails create are associated with increased atherosclerosis and subsequent risk of peripheral artery and coronary artery diseases such as heart attacks.

Many people think of TB as a rare disease that only affects people in undeveloped countries, but that is not the case any more. The HIV virus suppresses the immune system, making people who are HIV-positive far more vulnerable to tuberculosis bacteria. Can I catch TB from someone who has it? Tuberculosis is a bacterial disease that can be spread from one person to another.
You can catch tuberculosis through exposure to the bacteria in tiny droplets released into the air, which can happen when a tuberculosis patient coughs, sneezes, laughs or sings. Most people who have had appropriate medication for tuberculosis for at least two weeks are not contagious any more. Are some people at greater risk than others of catching TB? While anyone can get tuberculosis, there are risk factors that can increase your chances of catching the disease.
As mentioned above, one of the greatest risk factors is a weakened immune system. Your immune system may be compromised through HIV infection or other illnesses and drugs, including diabetes, end-stage kidney disease, certain cancers, immunosuppressant drugs such as those used for transplant patients , malnutrition, and simply being very young or very old.
People located in certain geographic locations have a higher risk of acquiring TB than others. Lifestyle factors also play a role, such as cigarette smoking and substance abuse, both of which weaken your immune system and leave you more vulnerable to TB. Working in a health care environment in which you are exposed to tuberculosis patients also increases your risk, and that can include working in prisons, nursing homes or immigration centers.
Regular use of a mask and thorough hand washing can significantly reduce your risk of catching TB in these environments.

TB in our ancestors Tuberculosis in humans is a very old disease. Recent research shows that the disease probably originated at least several hundred thousand years ago in hominids but perhaps even more than 2 million years ago. It has lesions on its skull indicating TB infection. Mycobacterium tuberculosis causes most TB cases in humans. Mycobacterium canetti and Mycobacterium africanum also cause TB in humans, while Micobacterium microti, Micobacterium caprae and Mycobacterium pinnipedii cause TB in other animals.
Together, these bacterium constitute the Mycobacterium tuberculosis complex. The bison had lesions symptomatic of TB. Bruce Rothschild and his colleagues carbon-dated a bone from the bison’s foot, calculating that the animal was 18, years old. TB was one of the probable factors responsible for its extinction. The earliest confirmed cases of TB in humans were found in the skeletal remains of a mother and her infant who were found in a submerged prehistoric site called Atlit-Yam, a few hundred metres offshore about 10 metres below sea-level, not far from Haifa in Israel.
The pair lived about 8 to 9, years ago in one of the earliest villages which had both domesticated animals and agriculture. The mother and infant had lesions suggesting TB on their skeletal remains. Using extremely careful techniques, to avoid contaminating their samples, a scientific team extracted bacterial DNA from the ribs, arms and long bones of the mother and infant. It matched DNA fragments of Mycobacterium tuberculosis.
