In short, most bacterial meningitis infections are mildly to moderately contagious person to person, while some viral meningitis are contagious but other types are not. Fungal, parasitic, and noninfectious causes of meningitis are not contagious from one person directly to another.

TB is contagious and can be spread to others by airborne droplets during sneezing, coughing, and contact with sputum, so you can get the disease by close contact with infected people; outbreaks occur in crowded conditions. The incubation period may vary from about two to 12 weeks.

Tuberculosis (TB) is an acute or chronic bacterial infection found most commonly in the lungs.

A skin test is the only way to tell if you have TB infection. The test is "positive" if a bump about the size of a pencil eraser or bigger appears on your arm. This bump means you probably have TB infection. Other tests can show if you have TB disease.

Some bacterial conditions themselves aren't contagious, but the bacteria that can potentially cause them are contagious. For example, the Staphylococcus bacteria itself can be transmitted from person to person through direct skin-to-skin contact, including through contact with fluids or pus from an infected wound.

Bacterial meningitis is usually less contagious than viral; depending on the bacterial genus causing the infection, it may be contagious during the incubation period and for about an additional seven to 14 days. And they can be contagious for much longer (many days to months) if the person becomes a carrier.

Bovine TB (Mycobacterium bovis (M. bovis)) in deer is a notifiable disease. In GB deer are thought to be generally spill over hosts of bovine TB where TB occurs within the species only as long as there is input from an external source.

Must not donate if Tuberculosis can be present in many tissues and be spread through the blood stream. It is sensible to exclude people who may have active disease from donating to prevent any possibility of transmitting the infection.

This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings. Although tuberculosis is contagious, it's not easy to catch. You're much more likely to get tuberculosis from someone you live with or work with than from a stranger.

Pulmonary TB is a bacterial infection of the lungs that can cause a range of symptoms, including chest pain, breathlessness, and severe coughing. Pulmonary TB can be life-threatening if a person does not receive treatment. People with active TB can spread the bacteria through the air.

Kidney disease. Chronic kidney disease. Tuberculosis (TB) is a stigmatizing and highly contagious disease that is transmitted by Mycobacterium tuberculosis through respiratory droplets.

Caused by the bacterium Mycobacterium tuberculosis, TB is likely the most widespread human infectious disease. Although it primarily affects people, it can rarely affect various animal species as well, including pets. The relevance of dogs to human TB is unclear: we know dogs can (rarely) be infected by M.

You need to stay home from work or school so that you don't spread TB bacteria to other people. After taking your medicine for a few weeks, you will feel better and you may no longer be infectious to others. Your doctor or nurse will tell you when you can return to work or school or visit with friends.

tuberculosis is transmitted through the air, not by surface contact. Transmission occurs when a person inhales droplet nuclei containing M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2).

Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings. Although tuberculosis is contagious, it's not easy to catch.
