Measles is caused by the measles virus (a paramyxovirus).
How is measles spread?
Measles is spread through droplet transmission from the nose, throat, and mouth of someone who is infected with the virus. These droplets are sprayed out when the infected person coughs or sneezes. Among unimmunized people exposed to the virus, over 90% will contract the disease. The infected person is highly contagious for
four days before the rash appears until four days after the rash appears. The measles virus can remain in the air (and still be able to cause disease) for up to two hours after an infected person has left a room.
How does one become immune to measles?
Anyone who has had measles is believed to be immune for life. People who have received two doses of vaccine after their first birthday have a 98% likelihood of being immune. Infants receive some immunity from their mother. Unfortunately, this immunity is not complete, and infants are at increased risk for infection until they receive the vaccination at 12 to 15 months
of age.
Who is at risk for getting measles?
Those people at high risk for measles include:
children less than 1 year of age (although they have some immunity passed
from their mother, it is not 100% effective);
people who have not received the proper vaccination series;
people who received immunoglobulin at the time of measles vaccination;
people immunized from 1963 until 1967 with an older ineffective killed measles vaccine.
Are measles deadly?
Measles can kill you. In 2008, approximately 164,000 people died of measles in the world. However, measles is rarely fatal in the United States. This is due to the fact that most people are immunized, which results in very infrequent outbreaks. Also, people most likely to have complications (including death) are those who are malnourished or who have weakened immune systems
What is the danger of getting measles while pregnant?
If you contract measles while you are pregnant, you may have a miscarriage, a stillbirth, or a preterm delivery. There appears to be no risk of having birth defects (unlike an infection with the
rubella virus, known as German measles).
If I am exposed, how long does it take to develop symptoms?
The typical time from exposure to a person infected with measles to development of the initial symptoms is 10-12 days (the range
is seven to 21 days). The rash occurs a few days after the initial symptoms (ranges from
seven to 18 days from exposure).
The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
Most sore throats are caused by viruses or mechanical causes (such as mouth breathing) and can be treated successfully at home. However, a person should be seen by a health care professional if they have a sore throat that has a rapid onset, and is associated with a fever or tenderness of the front of the neck; a sore throat that causes the person to have difficulty swallowing (not just pain swallowing) or breathing; or if a sore throat lasts for more than a week.
Diarrhea is a change is the frequency and looseness of bowel movements. Cramping, abdominal pain, and the sensation of rectal urgency are all symptoms of diarrhea. Absorbents and anti-motility medications are used to treat diarrhea.
Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly. They can sometimes be tender, painful or disfiguring. The treatment of swollen lymph nodes depends upon the cause.
Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
Mumps is an acute viral illness caused by the mumps virus. Symptoms of mumps include fever, headache, muscle aches, tiredness, and loss of appetite; followed by swelling of the salivary glands.
Encephalitis is a brain inflammation that causes sudden fever, vomiting, headache, light sensitivity, stiff neck and back, drowsiness, and irritability. Meningitis is an infection that causes inflammation of the meninges that surround the brain and spinal cord. Symptoms of meningitis include high fever, headache, nausea, vomiting, and stiff neck.
German measles is a disease that's caused by a virus. Symptoms include rash and fever for two to three days. The MMR (measles, mumps, and rubella) vaccine prevents this disease.
