Early in life, children can be afflicted by many diseases. Sometimes these are bacterial, for example meningitis or scarlet fever, whooping cough, strep throat and ear infections. Other diseases are viral and these include the common cold, chicken pox and bronchitis. It is important to know which of these your child is experiencing as treatments are different for bacterial and viral diseases.
Some diseases are easily identified by telltale symptoms, but whenever in doubt it's always best to visit your GP and have a proper diagnosis.
If you child has spots, bumps, or rashes that you cannot identify or are suffering from fever, coughs and sneezes it is always advisable to contact your doctor as soon as possible.
