Swine Flu Prevention and Treatment
Swine Flu Prevention and Treatment
The “swine flu” outbreak that started in the spring of 2009 is caused
by a specific H1N1 influenza A virus that is comprised of two swine
strains, one human strain, and one avian influenza strain. This influenza
virus can be transmitted from person to person. Infected persons are
likely to be contagious for at least 7 days after symptoms begin, and
possibly longer in children, the elderly, and persons with chronic conditions.
The most common signs and symptoms of the 2009 H1N1 influenza
A virus include fever, cough, sore throat, and headache. Symptoms may
range from mild to severe, possibly requiring hospitalization.
A vaccine to prevent pandemic H1N1 influenza A infection is planned
and should become available early to mid-October 2009. Pregnant women,
caregivers of children less than 6 months of age, healthcare workers, and
persons between 6 months to 24 years of age are particularly recommended
to receive vaccination. Oseltamivir (Tamiflu) and zanamivir
(Relenza) are antiviral neuraminidase inhibitor medications. Antivirals
should be started as soon as possible after the appearance of influenza
symptoms. If persons infected with H1N1 influenza A develop pneumonia,
antibacterial medications may be prescribed.
