The Health Protection Agency (HPA) has confirmed that seven cases of measles have been reported so far this year. More than 74 contacts linked to these cases have been identified and are being monitored.
Health officials noted that measles transmission is rising globally and in neighbouring countries. The agency advised the public to seek medical attention without delay if they develop cold‑like symptoms followed by red spots on the skin.
According to the HPA, the first rashes typically appear on the face and neck, before spreading to the chest, back, arms and legs.
Measles spreads through droplets when an infected person coughs or sneezes. The virus can remain suspended in the air inside an enclosed space for up to two hours, creating a high risk of infection. Transmission can also occur by touching contaminated surfaces and then touching the eyes, nose or mouth.
People who are not immune or have not completed both doses of the measles vaccine face a significantly higher risk of infection.
The disease can spread from an infected person four days before the rash appears and four days after it begins.
