Your nose is running, your throat is sore and your head feels full of cotton wool but just how bad is it? Check your symptoms and find out what medication to be taking.
A sore throat is partly a disease in itself and partly an effect of other diseases such as flu and glandular fever.
The incubation period between picking up the infection until the disease breaks out, is two to four days or sometimes less.
Viruses can't multiply on their own, so they have to invade a 'host' cell. Bacteria are capable of multiplying by themselves, as they have the power to divide.
Before the disease breaks out, one to two weeks may pass with symptoms that are similar to those of flu so make sure you know the signs of glandular fever.
Pneumonia is still a common disease. Many people die from it every year, most commonly women and people over the age of 70. The overall death rate due to pneumonia is currently 5 per cent.
