Explanation

 Prevalence is indeed a useful measure for evaluating the occurrence of chronic diseases within a population

Explanation

In statistics, the median is indeed often referred to as the 50th percentile.

This means that 50% of the values in a dataset are below the median, and 50% are above it

Explanation

Case-control studies are particularly efficient for rare diseases because

They begin by identifying a sufficient number of diseased people (or people have some "outcome" of interest) to enable you to do an analysis that tests associations.

Explanation

Carpus (bones of the wrist) is classified as short bone

Additional information:

Short bones are designated as those bones that are more or less equal in length, width, and thickness.

They include the tarsals in the ankle and the carpals in the wrist. 

Explanation

BCG vaccine is given at birth or as soon as possible thereafter.

It should not be given to children who have signs and symptoms of AIDS.

One dose of 0.05 ml.

If there is no scar at the injection site six weeks after a BCG immunization, the injection must be repeated.

This timing helps protect against tuberculosis (TB) in infants, as TB can be particularly severe in this age group.

Explanation

Measles is a highly contagious disease caused by a virus.

It spreads easily when an infected person breathes, coughs, or sneezes.

It can cause severe disease, complications, and even death. 

It can affect anyone but is most common in children

Additional information:

Malaria is not a viral disease

it's caused by a protozoan parasite of the genus Plasmodium. 

Explanation

Long bones are found in:

• the arms (humerus, ulna, radius)
• legs (femur, tibia, fibula),
• fingers (metacarpals, phalanges) 
• toes (metatarsals, phalanges)
  

Explanation

Prevalence and incidence are distinct epidemiological measures

Their interpretations vary, especially in the context of diseases like measles.

Additional information:

Incidence: Refers to the rate of new cases of a disease occurring within a specific population over a defined period. 

Prevalence: Reflects the total number of existing cases (both old and new) of a disease within a population at a particular point in time.

Explanation

Enforcement of traffic laws serves as a fundamental pillar in preventing traffic accidents due to several logical reasons:

• Deterrence of Risky Behavior:
• Promotion of Compliance:
• Modification of Driver Attitudes:
• Identification and Removal of Hazardous Drivers: 
• Education and Awareness:

Additional information:

While all the options listed are important in promoting road safety,

Enforcing traffic laws ensures that drivers adhere to speed limits,

Follow traffic signals, avoid reckless driving behaviors,

And maintain safe distances from other vehicles.

Explanation

The incubation period of influenza, is the time between exposure to the virus and the onset of symptoms

typically ranges from 1 to 4 days, with an average of about 2 days.
