United Nations: Issuing a new set of guidelines for the use of drugs against swine flu, the World Health Organization (WHO) has said otherwise patients with uncomplicated illnesses do not need to take antiviral drugs.
Worldwide, most infected patients continue to display typical influenza symptoms and fully recover within a week without any form of medical treatment, the WHO said.
According to the new guidelines, formed by consensus by a global group of experts, patients with uncomplicated illnesses do not need to be treated with antiviral medicines.
The guidelines emphasise using drugs such as oseltamivir and zanamivir, to which the pandemic virus is susceptible, to prevent severe illness and deaths, reduce the need for hospitalisation, and shorten hospital stays.
When properly prescribed, oseltamivir is found to significantly curb the risk of pneumonia, a leading cause of death for both the pandemic and seasonal influenza, it said.
WHO recommends treatment with the drug as soon as possible among people who are severely or whose conditions begin to deteriorate. Where oseltamivir is not available, zanamivir can be given. The virus is currently resistant to a second class of antiviral, known as M2 inhibitors.
As pregnant women are among the groups considered to be at increased risk, WHO recommends that they receive antiviral treatment as soon as possible after the onset of symptoms.
