Study Notes
Measles Overview
- Measles is a viral infection, once common, now largely preventable with a vaccine.
- It can be serious and even fatal, especially in young children.
- Death rates are decreasing globally, but still cause over 100,000 deaths annually, mostly in children under 5 years old.
Symptoms
- Symptoms appear 10-14 days after exposure.
- Common symptoms include fever, dry cough, runny nose, sore throat, inflamed eyes (conjunctivitis).
- Tiny, white spots with bluish-white centers on a red background (Koplik's spots) inside the mouth.
- Skin rash of large, flat blotches that often combine.
- Infection progresses through stages over 2-3 weeks.
Infection and Incubation
- The measles virus incubates for 10-14 days without symptoms.
- Initial symptoms are often mild, including fever, cough, runny nose, inflamed eyes, and sore throat.
- These initial symptoms last 2-3 days.
- Rash develops around 3-5 days after initial symptoms. Rash starts on face, spreads down the body, and fades in the same order.
- Rash is a characteristic symptom that looks like small red spots, bumps, and patches that make the skin appear splotchy.
Communicable Period
- A person with measles is contagious for around 8 days.
- Contagion begins 4 days before the rash appears and continues for 4 days after.
Causes
- Measles virus spreads through droplets from coughs, sneezes, or talks.
- The virus can also remain active on surfaces for hours.
- Transmission generally happens when a person who is infected touches a contaminated surface and then touches their nose, mouth, or eyes.
- About 90% of susceptible people exposed to the virus will get infected.
Risk Factors
- Unvaccinated status increases risk.
- International travel to areas with higher measles incidence increases risk.
- Vitamin A deficiency makes people more vulnerable.
Complications
- Bacterial ear infections.
- Inflammation of the voice box (larynx) and/or airways (bronchitis, laryngitis, or croup).
- Pneumonia can occur, especially in individuals with compromised immune systems.
- Measles can cause encephalitis, a complication involving brain inflammation. Complications may occur during or months after the illness.
- Pregnancy complications, including preterm labor, low birth weight, and maternal death, can arise if a pregnant woman contracts measles.
Prevention
- Vaccination is highly effective.
- The first dose is typically given at 12-15 months of age, and the second dose between 4 and 6 years.
- If someone is not up-to-date on their vaccinations, vaccinating them as soon as possible is important to prevent infection.
Diagnosis
- Clinical assessment based on symptoms (fever, cough, runny nose, conjunctivitis, Koplik spots, rash).
- Laboratory confirmation with blood tests to detect measles-specific IgM antibodies or viral culture.
- Koplik spots are an early symptom and can help doctors confirm the diagnosis early.
Management
- Supportive care, including hydration and fever management.
- Vitamin A supplementation is recommended in severe cases.
- Isolation is important to prevent the spread of infection.
Post-Exposure Vaccination
- Non-immunized people can receive the measles vaccination within 72 hours of exposure to help prevent infection.
- If infection happens, symptoms may be less severe or shorter in duration.
Treatment
- No specific treatment exists to cure an established measles infection.
- Symptoms can be managed by supportive care.
Medications
- Fever reducers like acetaminophen, ibuprofen, or naproxen can help with fever symptoms.
Other Important Notes
- Avoid giving aspirin to children or teenagers with measles symptoms to prevent rare but serious side effects.
- Antibiotics may be prescribed if bacterial complications develop.
- People with weakened immune systems should receive extra care and attention if exposed to measles.
