'Twice as contagious': Health alert over fast-spreading virus 'far more serious' than common cold

Authorities have issued a new alert after hundreds of measles cases were confirmed since January

Health officials have sounded the alarm about measles spreading at an alarming rate across England, warning that the virus transmits nearly twice as easily as your typical cold virus.

The UK Health Security Agency has stressed just how serious the situation is after England recorded 811 confirmed measles cases since January.


The health body pointed out that while we all know colds spread quickly, measles is far more contagious and much more dangerous.

Fortunately, infections are completely preventable, with the MMR jab offering excellent protection. Vaccination rates have been dropping in recent years, however, leaving more children vulnerable to this highly infectious disease.

Most cases - the vast majority, in fact - have struck children aged 10 and younger. What's more, about a quarter of infections have hit teenagers and adults over 15.

Government data suggests these numbers might actually be worse than they appear, as reporting delays mean the most recent month's figures likely don't capture the full scale of the outbreak.

Measles, according to the UKHSA, can trigger a host of physical complications like ear infections, pneumonia, and even brain inflammation.

These complications often land people in the hospital and, though rare, can sometimes cause lasting disability or even death.

Parents wondering about their child's vaccination status should start by checking their little one's red book - the personal child health record every child gets.

If you're not sure whether they're up to date, or if you can't find the information, just ring your GP surgery, who will have all the records and can book any missing jabs.

Spotting measles early matters. It kicks off much like any cold would. After a few days, a telltale rash appears. Some children also get tiny spots inside their mouths.

The rash typically shows up first on the face and behind the ears before spreading across the body. These spots can join up into larger patches, though they don't usually itch.

Ring your GP or NHS 111 straight away if you think you or your child might have measles. It's especially urgent if your baby is under one and has been near someone with the illness.

Pregnant women and those with weakened immune systems need immediate medical advice after any measles exposure. The same goes if you or your child hasn't had measles before or missed the two MMR doses.

Watch for warning signs like high temperatures that won't budge with paracetamol or ibuprofen, breathing difficulties, poor feeding in babies, or reduced urination. If you're worried something's seriously wrong, trust your instincts and seek help.

Remember to phone ahead before visiting your GP - measles spreads so easily that surgeries need advance warning.
