Hello all,
I work for the Health Department here, and this is part of an email all staff received today:
What is the swine flu?
Swine influenza (swine flu) is a respiratory disease of pigs caused by type A influenza viruses (these cause regular outbreaks in pigs). People do not usually get swine flu, but human infections can and do happen. Swine flu viruses have been reported to spread from person to person, but in the past this transmission was limited and not sustained beyond three people.
In late March and early April 2009, cases of human infection with swine flu (H1N1) were reported in Mexico and some parts of the United States (US). These have indicated that person to person transmission has occurred to a greater extent that has been reported in the past. The majority of cases have occurred in Mexico, mainly affecting healthy young adults. While some of these cases have been severe, initial cases in the US have not been severe.
While there have been several suspected cases identified in Australia, currently no cases of this strain of influenza have been confirmed in Australia after rigorous health testing has been completed.
Transmission
Swine flu is contagious and is spreading from human to human. However, at this time, it is not known how easily the virus spreads between people.
Swine flu is thought to be spread from person to person in the same way seasonal influenza and other common respiratory infections spread.
Being in close contact (eg. within a metre) with an infected person while they are talking, coughing or sneezing puts you at risk of becoming infected. Virus-containing droplets can land on the surfaces of the mouth, nose and throat of people close by. The virus may also be spread through contact with infectious respiratory secretions (i.e. sweat) on the hands of an infected person or other objects and surfaces.
Infectious Period
People with swine flu should be considered potentially contagious as long as they are symptomatic and possibly for up to seven (7) days following the onset of illness. Children, especially younger children, might potentially be contagious for longer periods.
How do I protect myself?
Swine flu is thought to be spread from person to person in the same way seasonal influenza and other common respiratory infections spread. So the best way to protect you and your family from swine flu is to take the following proactive seasonal flu measures:
~stay home when you are sick;
~wash your hands frequently with soap and water or use an alcohol based hand gel;
~wash your hands prior to touching your eyes, nose and mouth;
~when coughing or sneezing, cover your mouth and nose with disposable tissues which should be disposed of immediately;
~don't share items such as cigarettes, glasses or cups, lipstick, toys or anything which could be contaminated with respiratory secretions;
maintain at least one metre distance from people who have flu-like symptoms such as coughing or sneezing;
~consult your doctor if you have a cough and fever and follow their instructions, including taking medicine as prescribed;
~if attending a medical practice or hospital Emergency Department, telephone beforehand so that they can arrange for you to be seen away from other people.
Symptoms
The symptoms of swine flu are similar to those of seasonal influenza, including:
fever;
cough;
sore throat;
body aches;
headache;
chills; and
fatigue.
Some people have also reported diarrhoea and vomiting associated with swine flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with swine flu infection in people. Like seasonal flu, swine flu may cause worsening of underlying chronic medical conditions.
Treatment
Antiviral medications such as oseltamivir (Tamiflu) and zanamivir (Relenza) can be used in the treatment of swine flu. Antiviral drugs are prescription medicines which fight against the flu by keeping flu viruses from reproducing in your body. Antiviral drugs work best if started soon after becoming sick (within 2 days of symptoms developing).
Antibiotics may be required for secondary bacterial infections such as pneumonia.
Health Outcome
Like seasonal flu, swine flu in humans can vary in severity from mild to severe.
Serious complications such as pneumonia can occur. People with existing health problems may be at risk of these conditions worsening if they develop swine flu.
We encourage you to talk with health practitioners if you have any questions or concerns.
Prevention tips
For both seasonal and swine flu, the best way to protect yourself and others is to:
~stay home when you are sick;
~wash your hands frequently with soap and water or use an alcohol based hand gel;
~wash your hands prior to touching your eyes, nose and mouth;
~when coughing or sneezing, cover your mouth and nose with disposable tissues which should be disposed of immediately;
~don't share items such as cigarettes, glasses or cups, lipstick, toys or anything which could be contaminated with respiratory secretions;
~maintain at least one metre distance from people who have flu-like symptoms such as coughing or sneezing;
~consult your doctor if you have a cough and fever and follow their instructions, including taking medicine as prescribed; and
~if attending a medical practice or hospital Emergency Department, telephone beforehand so that they can arrange for you to be seen away from other people.
