Answer 1

Correct Answer: Secondary attack rate is 30%

Rationale:

The secondary attack rate for measles is generally much higher than 30%. It typically ranges from 75% to 90% among susceptible individuals. This high rate is due to the highly contagious nature of the measles virus.
Measles is caused by the measles virus, which is a paramyxovirus. It is one of the most contagious infectious diseases, primarily spreading through respiratory droplets.

Explanation of Other Options:

Incubation period of 10 to 14 days

Rationale: The incubation period for measles is indeed around 10 to 14 days. This is the time from exposure to the virus to the onset of symptoms. During this period, the virus replicates in the body before causing symptoms.

More severe in malnourished

Rationale: Measles is more severe in malnourished individuals, particularly those who are vitamin A deficient. Malnutrition can weaken the immune system, making it harder for the body to fight off infections, including measles.

Subclinical infection

Rationale: Subclinical infections of measles can occur, though they are less common. In these cases, the individual is infected with the virus but does not exhibit the typical symptoms of measles. However, they can still spread the virus to others.

Conclusion:

Among the given options, the statement about the secondary attack rate being 30% is incorrect. The actual secondary attack rate for measles is significantly higher, often ranging from 75% to 90% among susceptible individuals. Understanding the true nature of measles, including its incubation period, severity in malnourished individuals, and potential for subclinical infection, is crucial for effective disease control and prevention.
