Question

Disease pneumonia is due to
(A) Virus
(B) Bacterium
(C) Cyanobacteria
(D) Protozoan

Answer 1

Hint: Pneumonia is an infection in one or both lungs that inflames air sacs that can fill with fluid. With pneumonia, the air sacs can fill with fluid or pus.

Complete Answer:
- It is caused by bacteria, viruses and fungi. The germs that induce pneumonia are contagious. This implies that they will spread from individual to individual. Through inhaling airborne droplets from a sneeze or cough, both viral and bacterial pneumonia will spread to others. By coming into contact with surfaces or objects that are infected with bacteria or viruses that cause pneumonia, you can also get these forms of pneumonia.
- From the setting, you can contract fungal pneumonia. It doesn't though, spread from person to person. Pneumonia can range from mild to life-threatening in severity.The most serious cases are babies and small children, people older than 65 years of age, and people with chronic problems or weakened immune systems.
- Depending on factors such as the type of germ causing the infection, and your age and general health, the signs and symptoms of pneumonia range from mild to severe. Mild signs and symptoms are often similar to symptoms of the cold or flu, but last longer.

Pneumonia signs and symptoms can include:
- Pain in the chest when you cough or breathe
- Confusion or changes in mental consciousness (in persons 65 years of age and older)
- Cough that could cause phlegm
- Fatigue
- Fever, Sweating and Restless Chills
- Lower than normal body temperature (in adults over 65 years of age and in people with weak immune systems)
- Dizziness, diarrhoea or vomiting
- Respiratory Shortness
- The most prevalent type of pneumonia is pneumonia acquired by the population. It happens outside of hospitals or other facilities for health care. It may be triggered by:

Bacteria: Streptococcus pneumoniae is the most prevalent cause of bacterial pneumonia. This form of pneumonia can occur on its own or after there has been a cold or flu. It can affect one segment (lobe) of the lung, a condition called lobar pneumonia.

Bacteria like organisms: Pneumonia can also be caused by Mycoplasma pneumoniae. Usually, it causes milder symptoms than other forms of pneumonia. An informal name given to walking pneumonia is this type of pneumonia, which is typically not severe enough to require bed rest.

Fungi: In people with chronic health conditions or compromised immune systems, and in people who have inhaled large doses of the organism, this form of pneumonia is most common. The fungi that cause it can be found in droppings of soil or birds and differ according to geographic location.

Viruses, with COVID-19 included. Some of the viruses that cause colds and the flu can trigger pneumonia. Viruses are the most common cause of pneumonia in kids younger than 5 years old. Viral pneumonia is usually mild. But it can become very dangerous in certain instances. Coronavirus 2019 (COVID-19) can cause pneumonia, which can become severe.

The correct Answer is option (B) Bacterium.

Note: To support pneumonia prevention: Just get vaccinated. To avoid some forms of pneumonia and the flu, vaccines are available. Speak about having these shots with your doctor. The recommendations for vaccination have changed over time, so be sure to confirm your vaccination status with your doctor, even though you remember getting a pneumonia vaccine beforehand.
