Childhood diseases that can strike adults

Some things we expect to be able to leave behind us when we grow up - first crushes, school ground teasing and acne to name but a few. But some of the illnesses we usually associate with childhood can strike when you're an adult. Read on to find out if you need to think again about nursery infections.

Sore throats

We tend to think that only children get tonsillitis, but this infection of the tonsils (in the back of the throat) can affect adults. Fortunately, it gets less common from your 20s onwards, when tonsils tend to shrink naturally. Most throat infections are caused by viral infections, especially in adults, so antibiotics don't help. However, 'warning symptoms' include:

  • A sore throat without a cough
  • A high temperature
  • Tender swollen glands on the front of your neck
  • White pus on the back of your throat (use a torch and look in the mirror).

If you have three or all four of these, see your GP about possible antibiotic treatment. Otherwise, simple painkillers and a few days of taking it easy should have you back to normal.

Head lice

These most unwelcome of invaders are most common among children. However, catching head lice from the grandkids could be considered a badge of honour - they need close head-to-head contact to spread, so it's a sure sign you're giving lots of cuddles! They have nothing to do with being dirty (they're just as fond of clean hair!) and don't cause serious complications, but can give you an itchy scalp. Your pharmacist can advise on special combs to detect head lice and what to do if you get them.


Catching chickenpox as a child, as 90% of us do, usually gives lifelong protection against further infection. Occasionally, adults do get this infection with its fever and clear blistery rash. If you get chickenpox as an adult, you should see your GP straightaway, as he or she may recommend a course of antiviral medicine which only works if it's started in the first 24 hours after the rash appears. If you're pregnant and don't know if you've had it, see your GP immediately if you come into contact with someone with chickenpox - a blood test can tell if you need treatment. Although they're caused by the same virus, you can't catch shingles from someone with chickenpox - watch my video below to find out why! 


If adults catch mumps they are more likely to get complications than children are. In men these include painful swollen testicles which affect up to one in four adult male sufferers and, rarely, inflammation of the brain. Mumps in early pregnancy may increase the chance of miscarriage. Fortunately this is one example of children's immunisations helping all of us. Before routine childhood immunisation against mumps was introduced, 1,200 people a year ended up in hospital with complications. Today, immunisation has reduced the number of cases among adults as well as children by over 90%. Thanks, kids!

Whooping cough

Last year saw a spurt in cases of whooping cough - almost 3,000 in England and Wales alone this year (compared to 300 over the same period in 2011). Does it mean whooping cough vaccine doesn't work? Absolutely not. Before the vaccine was introduced, up to 150,000 cases a year were reported in the UK. However, immunity from the vaccine wanes in adulthood, so adults are now more likely to get it than children. The vaccine is given to babies as they're the ones most likely to get complications, including pneumonia and even death. In adults, it causes distressing bouts of coughing which go on for a couple of months, but rarely gives rise to serious complications. However, if you become acutely short of breath, develop sharp chest pains when you cough or cough up blood or rusty sputum, do see your doctor.
