Pneumonia is an infection or inflammation of the lungs. The table gives information about four types of pneumonia.
| Streptococcal Pneumonia | Viral Pneumonia | Mycoplasma Pneumonia | Chemical Pneumonia | |
|---|---|---|---|---|
| Cause | Bacteria | Virus | Bacteria | Inhaling toxic fumes |
| Details of cause | Pathogen is transmitted through inhaled respiratory droplets when coughing or sneezing. | Pathogen is transmitted via inhaled droplets or by touching contaminated surfaces then touching mouth/nose. | Pathogen is transmitted through close contact with respiratory secretions. | Inhalation of harmful chemical vapors or toxic dusts over some time. |
| Effect on the body | Causes inflammation of air sacs; can be treated with penicillin. | Usually lasts for one to two weeks then a person recovers and cannot develop this strain again. | Can only cause severe symptoms if the patient has a pre-existing chronic lung condition. | Can cause severe lung irritation, swelling, and respiratory failure. |
For each of these questions choose your answers from the types of pneumonia shown in the table.
(i) List all the types of pneumonia that are caused by a bacterium.
(ii) Which type of pneumonia can be prevented by avoiding touching the face with contaminated hands?
(iii) Which type of pneumonia is a non-communicable disease?
(iv) Which type of pneumonia depends on a pre-existing medical condition to cause severe symptoms?
Explain why Viral Pneumonia cannot be treated using antibiotics. Use information from the table.
Complete each sentence to explain why a person cannot develop the same strain of viral pneumonia twice soon after infection.
Use the words from the list:
antibiotics**, antibodies, antigens, immune, red blood, vaccinated, **white blood
