Antiviral Drugs and Swine Influenza (pig Flu)

Antiviral Drugs For Swine Influenza (pig Flu) : benefit & Prevention

Antiviral Drugs
Antiviral drugs are prescription medicines (pills, liquid or an inhaler) with activity against influenza viruses, including swine influenza viruses. Antiviral drugs can be used to treat swine flu or to prevent infection with swine flu viruses. These medications must be prescribed by a health care professional. Influenza antiviral drugs only work against influenza viruses -- they will not help treat or prevent symptoms caused by infection from other viruses that can cause symptoms similar to the flu.
There are four influenza antiviral drugs approved for use in the United States (oseltamivir, zanamivir, amantadine and rimantadine). The swine influenza A (H1N1) viruses that have been detected in humans in the United States and Mexico are resistant to amantadine and rimantadine so these drugs will not work against these swine influenza viruses. Laboratory testing on these swine influenza A (H1N1) viruses so far indicate that they are susceptible (sensitive) to oseltamivir and zanamivir.

Benefits of Antiviral Drugs (pig flu /Swine Flu)
Treatment: If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious influenza complications. For treatment, antiviral drugs work best if started as soon after getting sick as possible, and might not work if started more than 48 hours after illness starts.

Prevention (Pig Flu / Swine Flu) : Influenza antiviral drugs also can be used to prevent influenza when they are given to a person who is not ill, but who has been or may be near a person with swine influenza. When used to prevent the flu, antiviral drugs are about 70% to 90% effective. When used for prevention, the number of days that they should be used will vary depending on a person’s particular situation.

CDC Recommendation
CDC recommends the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with swine influenza viruses.

Oseltamivir (brand name Tamiflu ®) is approved to both treat and prevent influenza A and B virus infection in people one year of age and older.
Zanamivir (brand name Relenza ®) is approved to treat influenza A and B virus infection in people 7 years and older and to prevent influenza A and B virus infection in people 5 years and older.
Recommendations for using antiviral drugs for treatment or prevention of swine influenza will change as we learn more about this new virus.
Clinicians should consider treating any person with confirmed or suspected swine influenza with an antiviral drug. Visit:http://www.cdc.gov/swineflu/recommendations.htm.for specific recommendations.

Stay Healthy (Pig Flu / swine influenza)

What You Can Do to Stay Healthy from Pig flu Virus
There are everyday actions people can take to stay healthy.

Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
Avoid touching your eyes, nose or mouth. Germs spread that way.
Try to avoid close contact with sick people.

Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.

Swine Influenza ( pig Flu) cases

Pig flu (swine flu)

Human cases of swine influenza A (H1N1) virus infection have been identified in the United States. Human cases of swine influenza A (H1N1) virus infection also have been identified internationally. The current U.S. case count is provided below.

An investigation and response effort surrounding the outbreak of swine flu is ongoing.
CDC is working very closely with officials in states where human cases of swine influenza A (H1N1) have been identified, as well as with health officials in Mexico, Canada and the World Health Organization. This includes deploying staff domestically and internationally to provide guidance and technical support.

CDC activated its Emergency Operations Center to coordinate the agency's response to this emerging health threat and yesterday the Secretary of the Department Homeland Security, Janet Napolitano, declared a public health emergency in the United States. This will allow funds to be released to support the public health response. CDC's goals during this public health emergency are to reduce transmission and illness severity, and provide information to assist health care providers, public health officials and the public in addressing the challenges posed by this newly identified influenza virus. To this end, CDC has issued a number of interim guidance documents in the past 24 hours. In addition, CDC's Division of the Strategic National Stockpile (SNS) is releasing one-quarter of its antiviral drugs, personal protective equipment, and respiratory protection devices to help states respond to the outbreak. Laboratory testing has found the swine influenza A (H1N1) virus susceptible to the prescription antiviral drugs oseltamivir and zanamivir. This is a rapidly evolving situation and CDC will provide updated guidance and new information as it becomes available.http://www.cdc.gov-April 28, 2009
