The United States is facing its largest measles outbreak in over 20 years, with health authorities confirming 1,618 cases nationwide. The Centers for Disease Control and Prevention (CDC) reports that about 12% of those infected required hospital care, and three people have died. Texas remains the epicentre, with roughly 800 cases recorded.

This year’s total is the highest since measles was declared eliminated in the US in 2000. Public health experts link the rebound to pockets of low immunisation that have left many children and adults vulnerable to this highly transmissible disease.

Measles spreads easily through airborne droplets when an infected person coughs, sneezes, talks or breathes near others. If an infectious person enters a room of unvaccinated individuals, as many as nine out of ten may become infected. The virus can remain in the air and on surfaces for up to two hours, increasing the risk in schools, transit and crowded indoor spaces.

Clinically, measles begins with a high fever, dry cough, red, watery eyes and a runny nose. A few days later, small white Koplik’s spots can appear inside the mouth, followed by a red, spreading rash that usually starts on the face and moves downward. The rash commonly lasts about a week; sufferers also report fatigue, sore throat, abdominal pain or vomiting.

Health professionals warn that measles can lead to severe, sometimes fatal complications, including pneumonia, encephalitis (brain inflammation) and serious dehydration. The highest risk groups include young children, pregnant women and people with weakened immune systems.

There is no specific antiviral cure for measles. Treatment focuses on relieving symptoms and preventing complications; vitamin A is sometimes given to reduce the risk of severe illness. Medical experts caution against self-medicating, as excessive vitamin A can be harmful. Most uncomplicated cases recover within 10 to 14 days.

Clinicians advise people with measles to isolate for at least four days after the rash appears to reduce onward transmission. Patients and carers should wear masks—ideally N95 respirators—and practise strict hand and respiratory hygiene. Anyone exposed should contact a healthcare provider without delay for guidance.

The CDC and local health agencies continue to stress vaccination as the primary defence. Two doses of the MMR vaccine (measles, mumps and rubella) offer nearly 97% protection. High coverage not only shields individuals but also interrupts community transmission, protecting infants and those who cannot be vaccinated for medical reasons.

Measles can also spread through direct contact, such as handshakes, sharing food or touching contaminated surfaces. Pregnant women infected during pregnancy can transmit the virus to their unborn child, and breastfeeding mothers should seek medical advice if exposed.

Public health officials say the outbreak is a stark reminder that vaccine-preventable diseases can re-emerge when immunisation rates decline. Parents are urged to review their children’s vaccination records and ensure both MMR doses are completed on schedule.

Before widespread vaccination, measles caused millions of illnesses and deaths worldwide. The disease was nearly eliminated in the US, but falling uptake in some communities has allowed it to return. With more than 1,600 cases this year, authorities call for renewed focus on prevention, awareness and collective responsibility.

The CDC is urging everyone to stay alert for symptoms, seek medical attention if unwell and get vaccinated if they are not protected. Ending the current outbreak, officials say, depends on coordinated public-health action and individual choices to maintain protection.
