Approximately 14.8 million adults have been diagnosed with COPD, and approximately 12 million people have not yet been diagnosed.

An estimated 12 million adults have been diagnosed with chronic obstructive pulmonary disease (COPD) and another 3.1 million with emphysema, both responsible for the destruction of lung tissue that leaves those affected struggling to breathe.

Chronic Bronchitis

Results revealed a 12% decrease — from 68 deaths per 100,000 person-years to 60 deaths per 100,000 person-years — in the combined COPD death rate for all countries from 2000 to 2015. But there also was a 12% increase in the number of total deaths for all countries from 180,950 to 203,090 estimated total COPD deaths.

The 5-year mortality rate for people with COPD typically ranges from 40% to 70%, depending on disease severity, while the 2-year mortality rate for people with severe COPD is about 50%.

That’s because COPD follows its own path in each person. Still, signs that you’re nearing the end include: Breathlessness even at rest. Cooking, getting dressed, and other daily tasks get more and more difficult.

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.

Weakened Immune Systems Our immune systems weaken as we age, therefore seniors may have a harder time fighting off infections like pneumonia.

Case-fatality rate was highest for pneumonia caused by S. aureus: 15.6 deaths/100 cases (Table 2). Pneumococcal pneumonia, Klebsiella, Pseudomonas, and S.

The long-term effects associated with early childhood pneumonia include restrictive or obstructive lung function deficits and an increased risk of adult asthma, non-smoking related COPD, and bronchiectasis. The studies underpinning these observations do however have important limitations.

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. If you have a weakened immune system or a severe case of pneumonia, the recovery period might be longer.

Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli). Breathing may be labored. A classic sign of bacterial pneumonia is a cough that produces thick, blood-tinged or yellowish-greenish sputum with pus.

Pneumonia is a lung infection. It can be caused by many different germs, including bacteria, viruses, and fungi. This article discusses pneumonia that occurs in a person who has a hard time fighting off infection because of problems with the immune system.

Healthy ways to strengthen your immune system

1. Don’t smoke.
2. Eat a diet high in fruits and vegetables.
3. Exercise regularly.
4. Maintain a healthy weight.
5. If you drink alcohol, drink only in moderation.
6. Get adequate sleep.
7. Take steps to avoid infection, such as washing your hands frequently and cooking meats thoroughly.

In bacterial pneumonia, bacteria reproduce in the lungs, while the body tries to fight off the infection. This response to bacterial invaders is called inflammation. When the inflammation occurs in the alveoli (microscopic air sacs in the lungs) they fill with fluid.
