Answer 1

b. a focal infection

Step-by-step explanation:

The term “focal infection” was introduced to the medical community by Frank Billings in 1912 and its proposition was that infected teeth or tonsils could be responsible for the production of various types of diseases in humans. That is, a focal infection refers to an infection in a particular part of the body that causes another type of disease. In this case, we can say that rheumatic fever after a throat infection is an example of focal infection.

Rheumatic fever, or infectious rheumatism, is an autoimmune inflammatory disease caused by Lancefield Group A beta-hemolytic streptococcus, which is responsible for throat infections and scarlet fever.
