A measles outbreak in 5 areas across the UK, including Liverpool, Cheshire and Greater Manchester is putting adults and children at risk, NHS chiefs warn.
Health bosses on Merseyside have warned that a common misconception that only children are susceptible to the illness is putting adults at risk.
They are urging households to make sure children are vaccinated against the highly infectious illness.
But Public Health England (PHE) also says many adults and teenagers are not aware they are also at risk.
The illness can prove serious and have severe complications, particularly in people with other conditions.
Symptoms can be worse in teenagers and adults than children, and include high fever, sore and watery eyes, coughing, aching, a blotch red brown rash and generally feeling unwell.
But two doses of the MMR vaccine - which also protects against mumps and rubella - can protect against measles.
The vaccine is free, safe and available from GPs.
Anyone with measles is advised to stay at home and phone their GP or NHS 111 for advice, to avoid spreading the illness.
