are chest infections infectious to others?

Good hygiene. Although chest infections generally aren't as contagious as other common infections, like flu, you can pass them on to others through coughing and sneezing. Therefore, it's important to cover your mouth when you cough or sneeze, and to wash your hands regularly.

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.

Most often, upper respiratory infection is contagious and can spread from person to person by inhaling respiratory droplets from coughing or sneezing. The transmission of respiratory infections can also occur by touching the nose or mouth by hand or other object exposed to the virus.

Is It Contagious? Walking pneumonia spreads through sneezes or coughs. But it spreads slowly. If you get it, you could be contagious (which means you could spread it to other people) for up to 10 days.

Most cases of pneumonia follow a viral upper respiratory tract infection. Typically, the viruses that cause these infections (respiratory syncytial virus, influenza, parainfluenza, adenovirus) spread to the chest and produce pneumonia there. Pneumonia also can be caused by bacterial infections.

Pleurisy is not spread from person to person; however, it may spread within the individual to occupy more space. This occurs when the underlying infectious causes further spread into the pleural space or when noninfectious causes result in fluid increases in the pleural space.

Acute bronchitis — is contagious. Bronchitis is an inflammation of the bronchial tubes. These are the airways that carry air to your lungs.

The infection most often spreads to around the tonsil. It can then spread down into the neck and chest. Swollen tissues can block the airway. This is a life-threatening medical emergency.

TB is not spread through sexual intercourse or kissing or other touch. TB bacteria are spread through the air from one person to another. When a person who has TB disease of the lungs or throat coughs, speaks, or sings, TB bacteria are spread in the air.

If your acute or chronic sinus infection is caused by a virus or fungi, it is possible to spread these pathogens to another person. Symptoms can potentially look like a common cold, which can later develop into a reoccurring sinus infection. Infection of the sinus caused by bacteria is not contagious.

Pneumonia is an infection of one or both of the lungs caused by bacteria, viruses, or fungi. It is a serious infection in which the air sacs fill with pus and other liquid. Lobar pneumonia affects one or more sections (lobes) of the lungs.
808984
It depends. Sinus infections caused by bacteria or allergies are not contagious. However, if your infection is caused by a virus, then it likely is contagious. Viruses can be spread from person to person, or even in the air through coughing or sneezing.
370969
Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.

Coughs are not contagious, but certain underlying diseases that produce a cough are contagious, and can be spread by droplets formed during coughing. Correspondingly, when the underlying disease process is no longer contagious, the cough no longer produces infectious droplets.
393234
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.

Is an upper respiratory infection contagious? A majority of upper respiratory infections are due to self-limited viral infections. Occasionally, bacterial infections may cause upper respiratory infections.

It usually causes 'kennel cough', an infection of the trachea and bronchi, but can spread deeper into the lungs, especially in young or old dogs, or dogs with a compromised immune system. Most other causes of bacterial pneumonia are not particularly contagious to other dogs.
