Swine Flu - What is it all about?

Swine flu is a viral infection that originated
in pigs. It was first isolated as a special
strain of flu in the 1930s and has only
infrequently crossed the species barrier and
infected people who were in direct contact with
the infected pigs. To give an indication of the
rareness of that happening, the USA has reported
only 10 cases of swine flu in the past five
years. However, in March of this year 8 cases
were confirmed.

The current outbreak of swine flu in Mexico is
causing concern because over 100 of the people
who contracted it have died. In Mexico the
strain of swine flu appears to be particularly
virulent.

Several people who have just visited Mexico have
become infected with the virus and inadvertently
carried it back to their own countries.
Outbreaks have been reported in the USA, Canada,
Spain, New Zealand and elsewhere. At this stage the
travelers with the flu have not developed complications
and are recovering.

In the USA, some schools reporting outbreaks of
suspected swine flu have closed and students
sent home as a precautionary measure to prevent
the virus from spreading.

Many countries have put measures in place to
deal with a possible epidemic or pandemic.
So far, no travel restrictions have been imposed
on flights to and from Mexico. Airlines are
allowing passengers to change their travel plans
to Mexico without having to pay the usual
penalties.

The World Health Organisation (WHO) is keep a
sharp eye on matters and has declared the flu a
"public health event of international concern."

What are swine flu symptoms?

They are similar to regular flu symptoms with
fever, congestion and coughing, body aches, sore
throat, fatigue. Those most at risk to develop complications
are people who are immune compromised, the elderly
and pregnant women.

What to do if you live in an area affected by swine flu?

Wash your hands with soap and water frequently
throughout the day. If you are at risk or
fearful of catching swine flu, wear a face mask
- the N99 is reported to be most effective - to
prevent you from inhaling the airborne virus.

If you have visited Mexico recently or come into
contact with someone who has and you develop any
of these flu symptoms, be sure to see your doctor
immediately.
