Pneumonia

What is pneumonia?

Pneumonia is an infection in one or both of the lungs. It causes the air sacs of the lungs to fill up with fluid or pus. It can range from mild to severe, depending on the type of germ causing the infection, your age, and your overall health.

What causes pneumonia?

Bacterial, viral, and fungal infections can cause pneumonia.

Bacteria are the most common cause. Bacterial pneumonia can occur on its own. It can also develop after you've had certain viral infections such as a cold or the flu. Several different types of bacteria can cause pneumonia, including:

Viruses that infect the respiratory tract may cause pneumonia. Viral pneumonia is often mild and goes away on its own within a few weeks. But sometimes it is serious enough that you need to get treatment in a hospital. If you have viral pneumonia, you are at risk of also getting bacterial pneumonia. The different viruses that can cause pneumonia include:

Fungal pneumonia is more common in people who have chronic health problems or weakened immune systems. Some of the types include:

Who is at risk for pneumonia?

Anyone can get pneumonia, but certain factors can increase your risk:

What are the symptoms of pneumonia?

The symptoms of pneumonia can range from mild to severe and include:

The symptoms can vary for different groups. Newborns and infants may not show any signs of the infection. Others may vomit and have a fever and cough. They might seem sick, with no energy, or be restless.

Older adults and people who have serious illnesses or weak immune systems may have fewer and milder symptoms. They may even have a lower than normal temperature. Older adults who have pneumonia sometimes have sudden changes in mental awareness.

What other problems can pneumonia cause?

Sometimes pneumonia can cause serious complications such as:

How is pneumonia diagnosed?

Sometimes pneumonia can be hard to diagnose. This is because it can cause some of the same symptoms as a cold or the flu. It may take time for you to realize that you have a more serious condition.

Your health care provider may use many tools to make a diagnosis:

If you are in the hospital, have serious symptoms, are older, or have other health problems, you may also have more tests, such as:

What are the treatments for pneumonia?

Treatment for pneumonia depends on the type of pneumonia, which germ is causing it, and how severe it is:

You may need to be treated in a hospital if your symptoms are severe or if you are at risk for complications. While there, you may get additional treatments. For example, if your blood oxygen level is low, you may receive oxygen therapy.

It may take time to recover from pneumonia. Some people feel better within a week. For other people, it can take a month or more.

Can pneumonia be prevented?

Vaccines can help prevent pneumonia caused by pneumococcal bacteria or the flu virus. Having good hygiene, not smoking, and having a healthy lifestyle may also help prevent pneumonia.

Whooping Cough

What is whooping cough?

Whooping cough, or pertussis, is a respiratory infection that can cause coughing fits. In serious cases, the coughing can become violent and rapid. You may cough so hard that you vomit. The name of the disease comes from the whooping noise you might make when you try to breathe in after coughing.

Whooping cough is very contagious and can affect anyone. But it can be especially serious in babies who did not yet get the vaccine. About half of babies under age one who get whooping cough need care in the hospital.

What causes whooping cough?

Whooping cough is caused by a type of bacteria called Bordetella pertussis. It spreads from person to person. People who have pertussis usually spread it through coughing, sneezing, or breathing very close to someone. It can also sometimes be spread by touching an infected surface and then touching your nose or mouth.

If you get pertussis, you are contagious for about 2 weeks after you start coughing. Antibiotics may shorten the time that you are contagious.

What are the symptoms of whooping cough?

The symptoms of pertussis usually start within 5 to 10 days after you are exposed. But sometimes you may not get symptoms until up to 3 weeks later.

Whooping cough usually starts with cold-like symptoms. They may last for 1 to 2 weeks and can include:

The early symptoms in babies can be different. They may only cough a little bit, or they may not cough at all. Babies may have apnea, which means that there is a pause in breathing. They may start to turn blue. If this happens, get medical care for your baby right away.

As whopping cough gets worse, the symptoms may include:

The coughing fits get worse and start happening more often, especially at night. You may have them for up to 10 weeks or more.

Recovery from this can happen slowly. Your cough gets milder and happens less often. The coughing fits can come back if you have another respiratory infection, even months after you first got whooping cough.

How is whooping cough diagnosed?

Your health care provider may use many tools to diagnose whooping cough:

What are the treatments for whooping cough?

The treatment for whooping cough is usually antibiotics. Early treatment is very important. It may make your infection less serious and can also help prevent spreading the disease to others.

Treatment after you have been sick for 3 weeks or longer may not help. The bacteria are gone from your body by then, even though you usually still have symptoms. This is because the bacteria have already done damage to your body.

Whooping cough can sometimes be very serious and require treatment in the hospital.

Can whooping cough be prevented?

Vaccines are the best way to prevent whooping cough. There are two vaccines in the United States that can help prevent whooping cough: DTaP and Tdap. These vaccines also provide protection against tetanus and diphtheria.

Babies and other people at high risk serious disease should be kept away from people who have whooping cough.

Sometimes health care providers give antibiotics to family members of people who have had whooping cough or people who have been exposed to it. The antibiotics may prevent them from getting the disease.
