Swine flu is presumptively diagnosed clinically by the patient's history of association with people known to have the disease and their symptoms.
Usually, a quick test nasopharyngeal swab sample is done to see if the patient is infected with influenza A or B virus. Most of the tests can distinguish between A and B types. The test can be negative no flu infection or positive for type A and B. If the test is positive for type B, the flu is not likely to be swine flu H1N1.
If it is positive for type A, the person could have a conventional flu strain or swine flu H1N1. However, the accuracy of these tests is questionable. Another method of definitively diagnosing Swine flu is by identifying the particular antigens associated with the virus type. In general, this test is done in a specialized laboratory.
However, it is not advisable to use these drugs indiscriminately, because viral resistance to them can and has occurred. Also, they are not recommended if the flu symptoms already have been present for 48 hours or more, although hospitalized patients may still be treated past the hour guideline. Severe infections in some patients may require additional supportive measures such as ventilation support and treatment of other infections like pneumonia that can occur in patients with a severe flu infection.
The best treatment for influenza infections in humans is prevention by vaccination. In early October , a nasal spray vaccine was released. It is approved for use in healthy individuals ages 2 through This vaccine consists of a live attenuated H1N1 virus and should not be used in anyone who is pregnant or immuno-compromised.
Subsequently, the injectable vaccine, made from killed H1N1, also became available in the second week of October. This vaccine is approved for use in ages 6 months to the elderly, including pregnant females. Both these vaccines have been approved only after they had conducted clinical trials to prove that the vaccines were safe and effective.
Vaccination to prevent H1N1 swine flu is suggested for pregnant women, people who live with or provide care for children younger than 6 months of age, health-care and emergency medical services personnel, people between 6 months and 24 years of age, and people from the ages of 25 through 64 who are at higher risk because of chronic health disorders such as asthma, diabetes, or a weakened immune system.
Another type of vaccine, named Influenza A [H1N1] Monovalent Vaccine Live, Intranasal, made available during the first week in October , is a live attenuated H1N1 flu vaccine that contains no thimerosal, and is sprayed into the nostrils. This vaccine is only for healthy people years of age. Symptomatic people should stay at home, avoid crowds, and take off from work or school until the disease is no longer transmittable about two to three weeks or until medical help and advice is sought.
Sneezing, coughing, and nasal secretions need to be kept away from other people. Quarantining patients is usually not warranted, but such measures depend on the severity of the disease.
