WITH the onset of winter, Globe readers are being advised to look out for early signs of meningococcal disease.

According to Professor Qutub Syed, director of Health Protection Agency Northwest, the virus is more prevalent at this time of year.

He said: "People should be particularly vigilant this year as we have swine flu in the community in addition to normal seasonal flu, so there is a lot of infection about".

The infection is caused by the germ meningococcus. It causes meningitis, inflammation of the brain lining, and/or blood poisoning.

Infection can occur at any age, though most cases are recorded in children under four years old.

Teenagers up to the age of 19 are the next most vulnerable group.

Early symptoms of the disease may include a sudden onset of high fever, a severe and worsening headache without any other obvious cause, severe neck stiffness and a dislike of bright lights.

Other symptoms are very cold hands and feet, drowsiness that can deteriorate into a fever and a rash that does not fade when pressed with a glass. due to bleeding under the skin.

Babies with meningococcal disease tend to be irritable when picked up and have a high pitched cry, stiff body and jerking movements.

Professor Syed continued: "People should not be unduly concerned, but if you suspect that someone has meningococcal disease, call the doctor immediately.

"If the doctor isn't available, take the patient to the nearest accident and emergency department. Prompt action is vital.

"The symptoms are not always present and this can be a problem, particularly in identifying the disease in babies and very young children. If a baby is obviously ill or distressed, parents should seek medical help immediately. Don't take a chance with a child’s health."
