- Exposure (Close Contact) to person with Swine Flu (H1N1 Flu)
- Questions about Swine Flu
- Your child has NO symptoms of Swine Flu (no fever, cough, sore throat, runny nose)
- Children with symptoms of Swine Flu following Exposure (Close Contact) should be managed using the Swine Flu (H1N1 Flu) topic
Exposure (Close Contact) to Swine Flu Definition: - HOUSEHOLD CLOSE CONTACT: Lives with a person with Swine Flu.
- OTHER CLOSE CONTACT (within 3 feet, 1 meter; touching distance) with a person with Swine Flu. Examples of such close contact include kissing or embracing, sharing eating or drinking utensils, close conversation, and any other direct contact with respiratory secretions of a person with Swine Flu. Includes being in the same child care center room or carpool.
- NOT CLOSE CONTACT: In same building. Activities such as walking by a person or sitting across a waiting room from a person with Swine Flu for a brief period of time (per CDC May 2009). Being in the same school, church, workplace or building also is not Close Contact.
- NOT CLOSE CONTACT: In same community. Lives in a community where there are one or more confirmed cases of Swine Flu is not an Exposure. Living in the same state or country (e.g., Mexico) carries even less risk.
HIGH-RISK Children for Complications From Swine Flu Children are considered HIGH-RISK for complications if they have any of the following conditions: - Lung disease (such as asthma)
- Heart disease (such as a congenital heart disease)
- Cancer or weak immune system conditions
- Neuromuscular disease (such as muscular dystrophy)
- Diabetes, sickle cell disease, kidney disease OR liver disease
- Diseases requiring long-term aspirin therapy
- Pregnancy
- Healthy children under 2 years old are also considered HIGH-RISK (CDC: September 2009)
- Note: All other children are referred to as LOW-RISK
Swine Flu (H1N1 Flu): General Information - Cause: The H1N1 virus is a combination virus that contains genes from swine flu, avian flu and human flu. Cases of swine flu in humans were first detected in Mexico during March 2009. An outbreak of swine flu in humans occurred in the U.S. and Canada in April 2009. By June 2009, the WHO declared it a global pandemic.
- Severity of Symptoms: Symptoms of swine flu can be mild to severe, just as with regular human flu. Thus far in the US and Canada, the symptoms have generally been mild to moderate.
- Transmission: The swine flu virus is spread via airborne droplets, from sneezing and coughing, just like other influenza viruses. It also can be transmitted by hands contaminated with secretions. It no longer has anything to do with pigs; it is only spread person-to-person. Swine flu is NOT transmitted by eating pork.
- Expected Course: Like regular flu, the fever lasts 2-3 days, the runny/congested nose 1-2 weeks and the cough 2-3 weeks. With some flu viruses, the fever lasts 4 or 5 days.
- Contagious Period: A person is contagious for 1 day prior to and for 7 days after the onset of symptoms (e.g., the fever and cough).
- Incubation Period: After exposure, a person will come down with swine flu symptoms in 4 to 6 days (5 days on the average). An outer limit rarely could be 7 days. This virus has a longer incubation period than seasonal flu (1 to 3 days).
- Attack Rate: The chance of getting swine flu depends on the degree of exposure and is always higher for household contacts. While the attack rate is unknown for this virus, it should be high (20-50%) because there is no natural immunity to swine flu viruses.
- Diagnostic Test: At this time, testing is mainly indicated for patients with severe disease (CDC, May 2009). Accurate testing takes 2 or 3 days.
- Treatment: See below.
- Prevention: Prevention measures include avoiding sick people and crowds (social distancing). Hand washing is very important. A complete list of preventive tips is available on the CDC website.
- Vaccine: The best way to prevent Swine (H1N1) Flu is to get a yearly seasonal flu vaccine. This year, H1N1 is included in the regular flu vaccine and no separate flu shot is needed.
Prescription Antiviral Drugs for Swine Flu - For optimal results, antiviral drugs (such as Tamiflu) should be started within 48 hours of the start of flu symptoms. They can be started later in some cases.
- The CDC recommends they be used for: 1) any patient with severe symptoms AND 2) for all HIGH-RISK children (see that list) with any flu symptoms.
- The CDC doesn't recommend antiviral drugs for LOW-RISK children with mild or moderate Swine Flu illness.
- Their benefits are limited: they usually reduce the time your child is sick by 1 to 1.5 days. They reduce the symptoms, but do not cure the disease.
- Side effects: Vomiting in 10% of children.
