People are being urged to get up to date with their vaccines after concerns about measles cases.

NHS Sussex has issued a warning over the "highly infectious disease", which can spread easily and cause "severe issues".

According to the heath service, the easiest way for people to protect themselves is to have the MMR vaccine.

NHS Sussex said: "Measles is highly infectious and can be passed on even before a rash appears.

"Make sure you are protected from becoming seriously unwell from measles by making sure you are up to date with your MMR (measles, mumps and rubella) vaccinations."

According to the health service, measles usually starts with cold-like symptoms followed by a rash.

When the disease spreads, this can lead to a number of serious problems such as pneumonia, meningitis, blindness and seizures.

A spokesman for the NHS said: "These problems are rare, but some people are more at risk. This includes babies and people with weakened immune systems."

The MMR vaccine, which protects against measles, is given for free on the NHS.

People can ask at their GP surgery if they are not sure whether they or their child has had the vaccine.
