More severe symptoms, including a high temperature (fever), headache and aching muscles can also occur, although these tend to be associated more with flu.

They're generally safe for older children and adults to take, but might not be suitable for babies, young children, pregnant women, people with certain underlying health conditions, and those taking certain other medications. Speak to a pharmacist if you're unsure.

When to see your GP

If you or your child has a cold, there's usually no need to see your GP as it should clear within a week or two.

You only really need to contact your GP if:

  • your symptoms persist for more than three weeks
  • your symptoms get suddenly worse
  • you have breathing difficulties
  • you develop  complications of a cold, such as  chest pain or coughing up bloodstained mucus

It might also be a good idea to see your GP if you're concerned about your baby oran elderly person, or if you have a long-term illness such as a lung condition. You can also phone NHS 111 for advice.

How do colds spread?

In general, a person becomes contagious from a few days before their symptoms begin until all of their symptoms have gone. This means most people will be infectious for around two weeks.

You can catch the virus from an infectious person by:

  • touching an object or surface contaminated by infected droplets and then touching your mouth, nose or eyes
  • touching the skin of someone who has the infected droplets on their skin and then touching your mouth, nose or eyes
  • inhaling tiny droplets of fluid that contain the cold virusthese are launched into the air when an infected person coughs or sneezes

Colds spread most easily among groups of people in constant close contact, such as families and children in school or day care facilities. They're also more frequent during the winter, although it's not clear exactly why.

A number of different viruses can cause a cold, so it's possible to have several colds one after the other, as each one may becaused by a different virus.

How can I stop a cold spreading?

You can take some simple steps to help prevent the spread of a cold. For example:

  • wash your hands regularly, particularly before touching your nose or mouth and before handling food
  • always sneeze and cough into tissues this will help prevent the virus-containing droplets from your nose and mouth entering the air, where they can infect others; you should throw away used tissues immediately and wash your hands
  • clean surfaces regularly to keep them free of germs
  • use your own cup, plates, cutlery and kitchen utensils
  • don't share towels or toys with someone who has a cold

It's been suggested that vitamin C,  zinc and garlic supplements may help reduce your risk of getting a cold, but there's currently not enough strong evidence to support this.
