Measles can cause a range of health issues, from mild systemic symptoms to serious complications, and it can be life-threatening in some cases. Here’s a concise overview of what measles can do to you. What measles is

• Measles is a highly contagious viral infection that typically presents with fever, cough, runny nose, red eyes, and a characteristic rash that spreads from the face to the rest of the body. It spreads mainly through respiratory droplets and can linger in the air for hours.

Common complications

• Ear infections (otitis media) are among the most frequent complications and can affect hearing in children.

• Pneumonia (a lung infection) is a significant and common complication, especially in young children and those with malnutrition or weakened immune systems.

• Encephalitis (inflammation of the brain) can occur in a minority of cases and may lead to brain damage or death; this risk is higher in very young children and people with weakened immune systems.

• Diarrhea and dehydration are common and can contribute to weakness and other health issues.

• Eye problems, including potential vision issues, can occur in some cases.

Less common but serious outcomes

• Subacute sclerosing panencephalitis (SSPE) is a rare, long-term complication that can occur years after measles infection and is typically fatal.

• Pregnant individuals face higher risks, including miscarriage, preterm birth, or fetal complications if measles is contracted during pregnancy.

Immunologic impact

• Measles can temporarily suppress the immune system, increasing susceptibility to other infections for weeks to months after the illness resolves. This immunosuppression can contribute to additional illnesses or complications.

Severity and risk factors

• Complications are more likely in young children under 5, older adults, pregnant people, those with malnutrition, and individuals with weakened immune systems (due to conditions like HIV or chemotherapy).

• The very young, the elderly, and people without vaccination are at greatest risk for severe disease and hospitalization.

Prevention

• Vaccination is the most effective way to prevent measles and its complications. The measles vaccine is typically given as part of the MMR (measles, mumps, rubella) vaccine series. Vaccine coverage greatly reduces transmission and protects vulnerable populations.

If you or someone you care for has measles

• Seek medical advice, especially for young children, pregnant individuals, or anyone with a weakened immune system. Early medical assessment can help manage symptoms, monitor for dehydration, and identify complications early.

• Maintain hydration, rest, and monitor fever and symptoms; avoid giving aspirin to children.
