Measles is an acute infectious disease caused by the measles virus, circulating commonly in children. The disease is transmitted from person to person mainly through the respiratory tract. The disease occurs all year round but usually occurs in winter - Spring.
1. What is Measles (Morbilli)?
Measles is an acute respiratory disease caused by a virus of the genus Morbillivirus of the family Paramyxoviridae. Characteristics to recognize measles in children are fever, inflammation of the respiratory and digestive tracts, conjunctivitis of the eyes, and a red maculopapular rash spreading in order from the face to the limbs and the whole body.
Measles is a widespread disease, so the disease constantly appears in the community, plus the spread of the disease is very fast, so it is easy to break out into an epidemic.
Age of disease is mainly in children under 10 years old, especially children under 5 years old. However, now the disease has appeared in adults because they have not been vaccinated or have been vaccinated but have not been vaccinated.
To date, measles is still a dangerous infectious disease causing epidemics and is one of the leading causes of death in children under 5 years old. The disease has a very high rate of infection, especially in the group of people who have not been immune to measles because they have not been vaccinated against measles, have never had measles before.

2. Symptoms of Measles
The disease has initial symptoms: fever, conjunctivitis, runny nose, cough and koplik nodules in the oral mucosa. Erythema appears from the 3rd to 7th day of illness. Initially from the face, then spread to the whole body and lasts from 4 to 7 days. Sometimes the disease ends in desquamation; Leukopenia is a common symptom of the disease.
The disease is more severe in children and adults. Complications of the disease can be caused by viral replication or bacterial superinfection including: otitis media, pneumonia, diarrhea, croup and encephalitis. Death is mainly in children under five years of age with the main cause being pneumonia, sometimes from encephalitis.
Measles is endemic disease in urban communities and can cause epidemics in 2-3 years. The majority of cases are in children who have not been immunized.
3. How measles is transmitted
The disease is transmitted by the air contaminated with droplets containing the virus, usually by direct contact with the secretions of the nose and throat of the patient. And sometimes, it can be spread by newly contaminated objects, nasopharyngeal secretions of the patient.
Measles is the most contagious infectious disease and the population immunity in the population needs to reach over 94% to cut off the transmission of the disease in the community.

4. How long is the incubation period for measles?
The incubation period for measles is about 10 days, but can range from 7 to 18 days from exposure to onset of fever, usually 14 days until rash appears, very rarely incubation period longer or shorter.
The disease is contagious from the beginning of the prodromal period until 4 days after the rash, at least 2 days after the rash. The vaccine virus has proven to be non-transmissible.
5. Subjects susceptible to measles
All people who have not been infected or are not fully immune to infection. Immunity is established after a sustained illness.
Infants born to mothers who have had measles in the past will receive passive maternal immunity between 6 and 9 months of age, or longer depending on the amount of maternal antibodies remaining during pregnancy , and the rate of reduction of antibodies in maternal blood. Immunization of infants at 9 months of age results in an immunity rate of 95-98%, re-immunization with an additional dose can increase the level of immunity up to 99%.
Babies born to mothers who have been immunized with the vaccine have fewer passive antibodies. These children are still susceptible to measles and need to be immunized earlier.
