PRECAUTIONS - Because the use of aspirin to treat influenza has been associated with Reye's syndrome, do not give aspirin. Use acetaminophen instead. - Do not assume that the child is better because the fever goes away for a day. It will probably recur. - Watch for complications and inform the doctor if they occur. - Do not allow the child to resume everyday activities until the temperature has been normal for at least two days. - Influenza vaccines are not generally recommended for children who do not fall into a "high-risk" category. A child with any viral infection of the upper respiratory tract will probably be described as having the "flu," particularly if the child also has chills, fever, a cough, and muscle aches. However, true influenza is a specific, highly contagious respiratory infection that occurs in epidemics in which large numbers of persons in a community get the disease within a short period of time. It is caused by the influenza A or influenza B virus and is transmitted by droplets from nose and throat discharges of persons who have the disease. Influenza has a short incubation period (the time it takes for symptoms to develop once a person has been exposed to the virus) of one to three days and is contagious for seven days, starting before symptoms appear. SIGNS AND SYMPTOMS The symptoms of influenza are sudden chills, a sharp rise in temperature to 102 degrees_F to 106 degrees_F, flushing, headache, sore throat, a hacking cough, redness of the eyes, and pains in the back and limbs. Young children may vomit and have diarrhea. Fever lasts three to four days and is followed by days of weakness and fatigue, during which the child is susceptible to other illnesses. Secondary bacterial complications are responsible for many of the serious outcomes of flu. Their presence is suggested by the following: the return of high fever after the child's temperature has been normal for three or four days; progressive worsening of the cough, changing from dry and hacking to loose and productive; formation of pus in the eyes; rapid breathing and shortness of breath beyond that expected from the fever; severe earache; stiff neck; confusion; and extreme weakness, exhaustion, or collapse. In isolated cases, flu cannot be diagnosed with certainty by physical examination. During an epidemic, the disease is diagnosed by similarity to other cases. HOME CARE The prescription for home care includes bed rest during the height of the fever and acetaminophen, not aspirin, for fever and pains. You should encourage the child to drink a lot of fluids. Keep the child isolated from the rest of the family, and do not let the child return to school until fully recovered. This will lessen the child's chances of getting another disease while his resistance is lowered by the influenza. PRECAUTIONS - Reye's syndrome has been linked to the use of aspirin to treat influenza. Although a cause-and-effect relationship has not been established, aspirin should not be given if your child is suspected of having influenza. Watch for signs of complications, and report them to your doctor. - If there are no complications, the fever accompanying influenza often peaks in two cycles. The child's temperature is elevated for a day or two, normal for a day, and then elevated for a day or two. Do not misinterpret 24 hours of normal temperature as indicating a "cure," and do not allow your child to resume normal activities until the temperature has been normal for two or more days. MEDICAL TREATMENT If complications occur, cultures, blood tests, antibiotics, and hospitalization may be required. Vaccines to prevent influenza are not very helpful for children. The influenza viruses have a number of different strains, which change their structures from year to year. Therefore, last year's vaccine may be useless against this year's virus. Moreover, reactions to influenza vaccines in children are frequent, although these reactions are rarely serious. At the moment, medical experts advise that only children at special risk from influenza should be immunized annually. The conditions that are considered special risks are rheumatic heart disease, congenital heart disease, hypertensive heart disease, cystic fibrosis, severe asthma, tuberculosis, nephrosis, chronic nephritis, chronic diseases of the nervous system, and diabetes.
