Measles complications awareness

Overview

Measles is a highly contagious viral infection that can cause serious complications, such as pneumonia and brain swelling. It is preventable with vaccination.

Measles is less common in countries with high vaccination rates, but outbreaks can still occur in communities where fewer people are vaccinated.

Anyone who has not been vaccinated against measles or who has not had the illness before can get it. It mostly affects young children, but adults can also become infected.

Symptoms

Common symptoms

• Fever (often high)
• Cough
• Runny or stuffy nose
• Red, watery eyes (conjunctivitis)
• Small white spots inside the mouth (Koplik spots)
• A red, blotchy rash that starts on the face and spreads down the body

Symptoms in children

• Same as common symptoms, but children may also develop ear infections, diarrhea, or vomiting.

Symptoms in older adults

• Older adults may have more severe symptoms and are at higher risk for complications like pneumonia.

Causes

Main causes

• Infection with the measles virus (paramyxovirus). It spreads through the air when an infected person coughs or sneezes.

Risk factors

• Not being vaccinated against measles
• Traveling to areas where measles is common
• Being around someone who has measles
• Having a weakened immune system (for example, due to medical conditions or treatments)

When to see a doctor

See a doctor urgently if:

• If you or your child have symptoms of measles and have not been vaccinated, contact a doctor right away.
• If someone with measles has difficulty breathing, confusion, or seizures, call your local emergency number immediately.
• If a child with measles is dehydrated (dry mouth, no tears, not urinating much) seek same-day medical care.

Book a routine appointment if:

• If you suspect measles but symptoms are mild, call your doctor’s office for advice. They may ask you to come in a way that avoids exposing others.

Diagnosis

A doctor usually diagnoses measles by looking at the rash and other symptoms and asking about recent exposure and vaccination history. They may also take a sample to confirm it.

Tests that may be done

• A blood test to check for measles antibodies
• A swab from the nose or throat to detect the virus (PCR test)
• Sometimes a urine sample

What to expect at your appointment

The doctor will ask about your symptoms, any contact with someone who has measles, and your vaccination records. They will examine your skin and the inside of your mouth. If measles is likely, they may recommend staying home to avoid spreading the virus. The results of lab tests usually take a few days.

Treatment

There is no specific medicine to cure measles. Treatment focuses on relieving symptoms and preventing complications, such as giving fluids to prevent dehydration and using medicines to lower fever.

Self-care at home

• Get plenty of rest.
• Drink lots of fluids (water, clear soups) to stay hydrated.
• Use a cool-mist humidifier to ease cough and sore throat.
• Keep the room dim if light bothers your eyes.
• Take over-the-counter fever reducers as directed by a pharmacist or doctor.

Medical treatments

For severe cases, hospital care may include intravenous fluids, oxygen, and medicines to treat complications like pneumonia or encephalitis. Vitamin A supplements are sometimes given to reduce the risk of serious complications, especially in children. No specific antiviral drug is used.

Living with this condition

If you or your child has measles, stay home away from others (including school, work, and public places) until at least 4 days after the rash appears. This helps prevent spreading the virus to others.

Lifestyle tips

• Rest as much as needed until the fever goes away and you feel better.
• Monitor for any worsening symptoms, such as trouble breathing or ear pain.
• Keep in touch with your doctor, especially if symptoms last more than a week.

Diet and exercise

Eat light, easy-to-digest foods like soups and toast. Drink plenty of fluids to replace what is lost from fever and sweating. Avoid heavy exercise until you have fully recovered.

Mental health and emotional wellbeing

Being isolated while sick can feel lonely or frustrating. Stay connected with friends and family by phone or video call. If you feel very down or worried, talk to your doctor or a mental health professional.

Prevention

Yes, measles can be prevented with the measles, mumps, and rubella (MMR) vaccine. Two doses of the vaccine provide about 97% protection.

Vaccines

The MMR vaccine is given to children as part of routine immunisation schedules in many countries, including the UK. Adults who have not been vaccinated or who did not have measles as a child can also get the vaccine. It is safe and effective.

Complications

If left untreated

• Pneumonia (lung infection) – the most common serious complication
• Encephalitis (swelling of the brain) – can cause seizures, hearing loss, or brain damage
• Severe diarrhea and dehydration
• Ear infections – may lead to permanent hearing loss
• Subacute sclerosing panencephalitis (SSPE) – a rare but fatal brain disease that can appear years after measles

Long-term outlook

Most people recover from measles without any long-term problems, especially if they have proper supportive care. Complications can be serious, but with early medical attention and good nursing care, the outlook is good. Vaccination remains the most powerful way to protect yourself and your community.
