About measles-like Vaccinations

Routine immunization of measles wind shin requires two inoculations!

What are Measles and Rubella?

(a) Measles (Measles)
This is caused by air, droplet, or contact infection of the measles virus.
After infection with the virus, the asymptomatic period (incubation period) lasts about 10 to 12 days. Subsequently, symptoms such as fever, cough, nasal discharge, glaze, and rash appear. For 3 to 4 days after the onset of symptoms, fever of around 38 ° C, cough, nasal discharge, and glaze continued, and if you think that the fever was about to drop temporarily, it became a high fever of 39-40 ° C again, and began to appear from the neck streaks and faces. The rash then spreads throughout the body. High fever resolves in 3 to 4 days, and the rash gradually disappears, but pigmentation remains for a while.
The main complications include bronchitis, pneumonia, otitis media, and encephalitis. Of 100 measles patients, about 7 to 9 otitis media, and about 6 pneumonia. Encephalitis occurs in about one or two in 1,000 people.
In addition, measles may develop severe encephalitis called subacute sclerosing panencephalitis (SSPE) after several years to 10 years, and in about 1 or 2 in 100,000 measles patients. Occurs.
About one in thousands of people with measles can die.

(b) Wind shin (Rubella)
Rubella is caused by droplet infection of the rubella virus. After infection with the virus, the asymptomatic period (incubation period) lasts about 2 to 3 weeks. After that, the main symptoms include rash, fever, and swelling of the lymph nodes behind the neck.
In addition, symptoms such as coughs, nasal discharge, and red eyes (hyperemia of the eye conjunctiva) may be seen. Complications include joint pain, thrombocytopenic purpura, and encephalitis.
Thrombocytopenic purpura is associated with about 1 in 3,000 rubella patients and encephalitis affects about 1 in 6,000 rubella patients.
When it comes to adulthood, it tends to be more severe than when it is a child.
If a pregnant woman becomes infected with rubella, it can also infect the baby on the stomach, resulting in a "congenital rubella syndrome", which is hard to hear, hard to see, and abnormal heart.
