Question

Assertion (A): Streptococcus pneumoniae and Haemophilus influenzae are responsible for causing infectious disease in human beings.

Reason (R): A healthy person acquires the infection by inhaling the aerosols released by an infected person.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Indeed, meningitis and pneumonia are among the infectious diseases that Streptococcus pneumoniae and Haemophilus influenzae cause in humans. By breathing in the aerosols that an infected person releases, a healthy person can contract these illnesses. When an infected person coughs or sneezes, they generate droplets or aerosols that others can inhale, which is how these bacteria are spread.
