Influenza Questions and No Close Contact in the Last 7 days

What You Should Know About Flu Exposure:

• For most healthy people, the symptoms of influenza are like those of a bad cold.
• But, with flu, the onset is more abrupt. The symptoms are more severe.
• Feeling very sick for the first 3 days is common.
• The treatment of influenza depends on your child's main symptoms. It is no different from treatment used for other viral colds and coughs.
• Most children with flu don't need to see their doctor.

Influenza Symptoms:

• The main symptoms are fever, cough, sore throat and runny nose.
• Most often, fever is present. Exception: sometimes, no fever if the child has a weak immune system.
• Other common symptoms are muscle pain, headache and fatigue.
• Some people also have vomiting and diarrhea, but never as the only symptom.

Influenza Diagnosis and Flu Tests:

• During influenza season, if your child has flu symptoms, he probably has the flu.
• Your child won't need any special tests.
• You should call your doctor if your child is High-Risk for complications of flu. These are children with chronic diseases. Examples of such diseases are asthma or a weak immune system. See the High-Risk list in Causes. Also, healthy children under 2 years of age are High-Risk.
• For Low-Risk children, you don't need to see your child's doctor.
• If your child develops a complication of the flu, then call your child's doctor. Examples of complications are an earache or trouble breathing. These problems are included in the "What to Do" section.

Influenza Treatment:

• For most children, the treatment of flu is based upon symptom relief. It's no different than the treatment of other viral coughs and colds.
• Tamiflu is the main antiviral drug used to treat influenza in some children.
• The AAP recommends it be used for any patient with severe symptoms.
• The AAP also recommends the drug for most High-Risk children. See that list in Causes. Mainly, it is used for children in the hospital or those with chronic diseases.
• Treatment is not recommended for Low-Risk children with normal flu symptoms. (AAP)
• Most patients recover without taking Tamiflu.
• Antiviral treatment must be started within 48 hours of the onset of flu symptoms. After 48 hours of fever, starting the drug is not helpful.

Return to School:

• Spread is rapid and the virus is easily passed to others. The time it takes to get the flu after contact is about 2 days. The range is 1-4 days.
• Your child can return to school after the fever is gone for 24 hours. (CDC).
• The influenza virus is spread in the air from sneezing and coughing.
• It also can be spread by the hands with flu germs on them.

What to Expect:

• The fever lasts 2 -3 days.
• The runny nose lasts 1-2 weeks.
• The cough lasts 2-3 weeks.

Influenza Prevention Questions

How to Protect Yourself from Getting Sick:

• Wash hands often with soap and water.
• Alcohol-based hand cleaners work very well.
• Avoid touching the eyes, nose or mouth. Germs on the hands can spread this way.
• Try to avoid close contact with sick people.
• Avoid ERs and urgent care clinics if you don't need to go. These are places where you are more likely to be exposed to flu.

How To Protect Others - Stay Home When Sick:

• Cover the nose and mouth with a tissue when coughing or sneezing.
• Wash hands often with soap and water. After coughing or sneezing are important times. Alcohol-based hand cleaners also work well.
• Limit contact with others to avoid getting them sick.
• Stay home from school or work while sick with fever. Your child can return to school after the fever is gone for 24 hours. (CDC).

Flu Shot:

• Getting a flu shot is the best way to protect your family from flu.
• Influenza vaccines are strongly advised for all children over 6 months of age. (AAP)
• Adults should also get the shot.
• The flu shot most often prevents the disease.
• Even if your child gets the flu, the shot helps to reduce the symptoms.
• A new flu shot is needed every year. Reason: flu viruses keep changing.
• After the flu shot, it takes 2 weeks to fully protect from flu. But then, the protection lasts for the full flu season. An antiviral medicine only protects from flu while taking it.

Antiviral Drug (such as Tamiflu):

• The drug Tamiflu may help prevent flu after close contact. But, it is only advised for some very High-Risk patients (CDC). See the High-Risk list.
• The CDC recommends early treatment if flu symptoms occur, not preventive treatment. Reasons: even after close contact, some children don't get flu. Also, Tamiflu is helpful only while your child is taking it. It won't prevent flu once your child stops taking it. To prevent flu, you would need to take the medicine every day for months.
• Most doctors also wait until flu symptoms start before treating with drugs.
• If your child is High-Risk, call your doctor within 24 hours of exposure. Your doctor will decide if an antiviral is needed.
• High-Risk adults with recent close contact should also call their doctor. The High-Risk adult group includes chronic disease, pregnant, or over 65.

Tamiflu Prescription Questions

Treating Influenza - Tamiflu:

• Tamiflu is a prescription anti-viral drug. It can be helpful in treating the flu virus.
• These drugs should be started within 48 hours of when flu symptoms start. After 48 hours of fever, starting the drug is not helpful. It's taken for a total of 5 days.
• When to Use: Severe symptoms OR underlying health problems (High-Risk group)
• For High-Risk children, call your child's doctor at the start of flu symptoms.
• Most healthy patients have mild to moderate symptoms. Tamiflu treatment is not needed for these patients.
• The benefits are limited. Tamiflu reduces the time your child is sick by 1 to 1.5 days. It helps reduce the symptoms, but does not make them go away.
• Tamiflu also has side effects. It causes vomiting in 10% of children.
• Also, it is not used to prevent flu. Reason: you would need to take the medicine every day for months.

Personal Stockpiling of Tamiflu - Not Advised:

• Some people want a prescription for Tamiflu for all family members. They want it on hand just in case they come down with flu. They currently are well and have not been exposed to flu.
• Doctors and the CDC are opposed to this practice. The AAP and your State's Public Health Department also do not support this.
• The supply of Tamiflu is limited. It is used for those with severe symptoms OR who are High-Risk.
