Tokyo: Boy under 5 infected with measles, calls for early vaccination. Measles is a viral infection that causes fever and rash.
It is highly contagious and can lead to severe complications such as pneumonia and encephalitis. The vaccination rate was 92.0%, down 1.2 percentage points from the previous year and below the 95% target for achieving herd immunity. The Tokyo Metropolitan Government believes this is due to an increase in cases of parents refraining from getting vaccinated at medical institutions.
