Common Causes of Pneumonia

Viruses, bacteria, and fungi can all cause pneumonia. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus).

Catching pneumonia

coughs and sneezes – these launch tiny droplets of fluid containing germs into the air, which someone else can breathe in. touching an object and transferring germs on to it – someone else can touch this object and then touch their own mouth or nose.

The three main causes of pneumonia are bacteria, viruses, or fungi. Treatment depends on the cause. Pneumonia is a type of infection that affects your lungs. It can affect one or both lungs.

Bacterial pneumonia can occur on its own or develop after you’ve had a viral cold or the flu. Bacterial pneumonia often affects just one part, or lobe, of a lung. When this happens, the condition is called lobar pneumonia.

It can take about six weeks to fully recover from walking pneumonia. However, most people recover from pneumonia in about a week. Bacterial pneumonia usually starts to improve shortly after starting antibiotics, while viral pneumonia usually starts to improve after about three days.

During COVID pneumonia recovery, your body first has to repair the damage caused to the lungs; then it has to deal with clearing leftover fluid and debris and, finally, scarring until the tissue is fully healed over — all of which come with unpleasant symptoms.

“Pneumonia can be incredibly taxing and there’s no one-size-fits-all to recovery. Some people feel better in about six weeks, but it can take several months for others to feel better after severe pneumonia,” adds Dr. Lee. “Most importantly, be patient with your body.”

Most people do eventually recover from pneumonia. However, the 30-day mortality rate is 5 to 10 percent of hospitalized patients. It can be up to 30 percent in those admitted to intensive care.

The symptoms of pneumonia can develop suddenly over 24 to 48 hours, or they may come on more slowly over several days. Common symptoms of pneumonia include: a cough – which may be dry, or produce thick yellow, green, brown or blood-stained mucus (phlegm)

Early phase (0–4 days) or stage 1: ground-glass opacities [12] (Fig. 1a); Progressive phase (5–8 days) or stage 2: crazy paving pattern [12, 13], extensive ground-glass opacities and small consolidations [12] (Fig. 1b–d);

If you have walking pneumonia caused by Mycoplasma pneumoniae, you can be considered contagious from two to up to four weeks before symptoms appear (called the incubation period). During this time, you will not realize you are contagious and spreading pneumonia.
