Measles

What is measles?

Measles is an infectious disease caused by the measles virus. It is very infectious and almost 100% of people who do not have immunity become infected. It can develop severe complications and can be life-threatening.
Even if measles is excluded in Japan, the measles virus may be brought in from overseas.
Measles is not a disease of the past! Let's get vaccinated to prevent measles!

Symptoms of measles

  1. Fever of 38°C or higher
  2. Cough, nasal discharge, conjunctival congestion
  3. Red rash of the whole body

※ If all 1-3 appear, measles is suspected. 
※ In particular, if you have traveled abroad, you need to be careful.

Route of transmission of measles

Measles is transmitted by droplet, air, and contact infection.

  • It is transmitted (splash infection or airborne infection) by inhaling air containing the measles virus, such as coughing and sneezing. There is also contact infection.
  • If the people around you do not have immunity, it is a very infectious disease that is said to infect 12 to 14 people (1 to 2 people with influenza) from one patient. Almost 100% of people without immunity become infected.
  • It has the ability to infect people around you from one day before symptoms such as fever and cough (3 to 5 days before the appearance of rash) to about 4 to 5 days after the appearance of rash (or 3 days after fever).

Complications of measles

Coordinating complications can be life-threatening. Complications are said to occur in about 30% of the total. Of these, pneumonia and encephalitis are a major cause of death from measles.
Complications include pneumonia, encephalitis, subacute sclerosing panencephalitis (SSPR), otitis media, curop syndrome (pharyngitis / pharyngeal tracheal tribula), and myocarditis.

When in contact with a measles patient

Measure your body temperature every day for 2 weeks (up to 3 weeks) from the date of last contact with a measles patient and observe your health. In the unlikely event that symptoms such as measles appear, contact a medical institution in advance and follow the instructions of the medical institution.

Measures against measles

  • When going to college or traveling abroad, there is an increasing need to prove that you have been vaccinated or that you have enough measles antibodies (resistance). In particular, if you go to an overseas school, you will be required to have Vaccinations twice.
  • A blood test (antibody titer test) to check for measles antibodies can be taken at a medical institution at your own expense.
  • Persons with weak immunity or those who often come into contact with children, such as medical care, welfare, education, childcare, etc., need to be vaccinated so that they do not spread measles as a source of infection. Some companies check their Vaccinations history when they get a job.

Wind shin

What is wind shin?

It is an infection caused by the rubella virus, which is characterized by fever, rash, and lymphadenopathy. After an incubation period of about 14 to 21 days (average 16 to 18 days), symptoms appear. Basically, it is a disease with good prognosis, but hospitalization may be required due to complications such as joint pain / arthritis, thrombocytopenic purpura and acute encephalitis.

Congenital rubella syndrome

When a pregnant woman becomes infected with the rubella virus in the first half of pregnancy, the fetus is also infected, resulting in a disorder that occurs in the birth of the child congenital rubella syndrome.
It is called (congenital rubella syndrome:CRS). Cataracts, heart disease, hearing loss (three main symptoms) can be seen.
