Everyday Science (BPSC) Health and Diseases

Consider the following statements:

1. Case fatality ratio (CFR) is the proportion of individuals diagnosed with a disease who die from that disease.

2. The infection fatality ratio (IFR) for a disease estimates proportion of deaths among all infected individuals.

Which of the statements given above is/are correct?

1 only

2 only

Both 1 and 2

Neither 1 nor 2

Case fatality ratio and Infection fatality ratio :

There are two measures used to assess the proportion of infected individuals with fatal outcomes. The fi rst is infection fatality ratio (IFR), which estimates this proportion of deaths among all infected individuals. The second is case fatality ratio (CFR), which estimates this proportion of deaths among identi fi ed con fi rmed cases.
The true severity of a disease can be described by the Infection Fatality Ratio:
Infection fatality ratio: = no. of deaths from disease/no. of infected individuals * 100.
Serological testing of a representative random sample of the population to detect evidence of exposure to a pathogen is an important method to estimate the true number of infected individuals
