Characteristics of measles virus
「MASHIN」, also called measles, is a virus that infects only people and spreads from person to person. It is highly contagious, and more than 90% of people who are not immune to measles are infected with measles virus and rarely have subclinical infection (Note 1).
Among viral infections, it is one of the viral infections that is particularly susceptible to “early childhood.”
- A condition in which a person is infected with a pathogen, such as a bacterium or a virus, but does not develop symptoms of infection.
Characteristics of measles symptoms
[Representative initial symptoms of measles].
- Fever (fever around 38 degrees)
- Cough (upper respiratory inflammation symptoms)
- Nasal discharge
- Bloodshot eyes (conjunctivitis)
- Koplik’s patches (a small white rash in the mouth)
After the catarrhal phase of measles, the fever temporarily falls, and the symptoms are temporarily relieved. However, about 12 to 18 hours after the fever has been relieved, the most severe symptom called the “rash phase” develops.
