What is Swine Flu (swine Influenza)?
Swine flue is a respiratory disease affecting pigs that us caused by type A influenza virus. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to influenza outbreaks in human. It causes high levels of illness but low death rates in pigs.
Does swine Flu affect humans?
Swine flu viruses that cause disease in pigs very rarely affect humans. However, sporadic human infections with swine flu have occurred. Most commonly, these cases occur in persons with direct exposure to pigs but there have also been documented cases of human-to-human spread of swine flu.
How does Swine Flu spread to humans?
Swine flu spreads to human mainly through contact with infected pigs, which shed the virus in their saliva, nasal secretions and faeces. Limited human-to human transmission can also occur in the same way as seasonal flu occurs in people.
Can people catch Swine Flu from eating pork?
There is currently no evidence to suggest that swine flu can be transmitted to human from eating pork or port products that have been thoroughly cooked.
What are the symptoms of Swine Flu in humans?
The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza. An early symptom is high fever, and this is followed by cough, sore throat, runny nose, and sometimes breathlessness a few days later
How can human infections with swine flu be diagnosed?
To diagnoses swine flu, a respiratory specimen would generally need to be collected within the first 4 to 5 days of illness (when an infected person is most likely to be shedding the virus). However, some persons, especially children may shed the virus for 10 days or longer.
What medications are available to treat swine flu infection in humans?
There are four different antiviral drugs that are licensed for use in Malaysia for the treatment of influenza; amantadine, rimantadine, oseltamivir and zanamivir. While most swine flu viruses have been susceptible to all four drugs, the most recent swine flu viruses isolated from humans are resistant to amantadine and rimantaine. At this time, the US CDC recommends the use of oseltamivir (Tamiflu®) or zanamivir (Relenza®) for the treatment and/or prevention of infection with swine flu viruses.
Is it safe to visit countries with cases of Swine Flu and will I be quarantined when I return? What travel precautions should I take?
There are currently no travel restrictions or quarantine advised by the World Health Organisation for swine flu. If you intend to travel to areas which have cases of swine flu (currently – southern California and Texas in the United States: and Mexico), you should take note of the following measures to minimize your risk of acquiring swine flu:
Avoid contact with persons with symptoms of influenza
Avoid crowded areas and maintain good ventilation
Observe good personal and environmental hygiene. Wash hands thoroughly with soap and water frequently and when they are contaminated by respiratory secretions e.g. after sneezing.
Maintain good body resistance through a balanced diet, regular exercise, having adequate rest, reducing stress and not smoking.
