What is measles?

Although cases are relatively uncommon thanks to the medical vaccine available, instances of measles can rise rapidly if an outbreak does occur.

Anyone who isn't certain whether they have been fully vaccinated or not should check with their GP.

What are the symptoms?

People with measles will face cold-like symptoms initially around seven to 10 days after being infected.

Symptoms include the following:

A blocked nose

Sneezing

Swollen, red eyes that may be sensitive to light

A high temperature, which may reach around 40C

Small greyish-white spots in the mouth

Aches and pains

Cough

Loss of appetite tiredness

General lack of energy

Rash

Sufferers will then get a measles rash a few days later, which consists of small red or brown, flat or slightly raised spots that may join together into larger blotchy patches, according to the NHS.

The rash will usually first appear on the head or neck, before spreading downwards.

The infectious condition normally clears up in under two weeks.

Who is most at risk?

Measles is a very contagious, serious disease that can be fatal in some cases, but this is rare.

It can affect people of all ages, but it is most common among young children.

People that are at risk the most of serious complications include young children, adults over 20 years old, pregnant women, and people with compromised immune systems.

How is measles spread?

Measles spread easily, it is one of the most infectious illnesses.

The virus can be contracted by spending even 15 minuted with someone who has the disease.

Germs can be spread by an infected person coughing and sneezing, which allows contagious tiny droplets of bacteria to linger in the air or settle on surfaces.

Someone can become ill once they inhale those droplets or touch a contaminated surface and then touch their nose, mouth or eyes.

Health experts advise wearing gloves, washing hands regularly, using antibacterial soap or gel and to avoid touching the eyes, nose or mouth as the virus can survive on surfaces for a few hours.

It is best to phone up to arrange an appointment before heading into a surgery.

How is measles treated?

To help relieve symptoms and to avoid spreading the virus, do the following:

To relieve fever, aches and pains take painkillers.

Drink lots of water to prevent dehydration.

Close any curtains or switch off lights to help reduce light sensitivity.

Use a damp cotton wool pad to help clean the eyes.

Do not go into school or work for at least four days from when the rash first appears.

Aspirin should not be given to children under 16 years old.
