Swine Flu - Prof. Lico Reis

Swine Flu

• There are many different types of swine flu and like human flu, the infection is constantly changing. • The outbreak in Mexico seems to involve a new type of swine flu that contains DNA typically found in avian and human viruses.

Introduction

• It is a contagious respiratory disease of pigs caused by type A influenza viruses.

Swine Flu - Definition

• While humans do not normally catch it they can contract the virus, usually if they have been in close contact with pigs. • It is possible for humans to pass it to each other and experts believe it spreads in the same way as seasonal flu - through coughing and sneezing.

How do humans catch it?

• The symptoms of swine influenza in people are similar to the symptoms of regular human seasonal influenza infection and include fever, fatigue, lack of appetite, coughing and sore throat. • Some people with swine flu have also reported vomiting and diarrhea.

What are the symptoms?

• More than 80 people have died and many more made ill, in Mexico in particular, although cases have also been reported in the US and New Zealand. • However, testing has shown that the antiviral drugs appear to be effective

How dangerous is it?

• The World Health Organisation warned the outbreak had "pandemic potential" and countries were advised to step up surveillance and preparation in case the infection spreads rapidly.

Why should we be worried about it?

• If the flu spreads over a wide geographic area and affects a large proportion of the population it goes beyond an epidemic and becomes a pandemic.

What is a pandemic?

• Many experts are monitoring the situation closely. • Anyone who has recently returned from affected countries should consult a doctor if they notice flulike symptoms. • The Government has advised people to follow general infection control practices and good hygiene to reduce transmission of all viruses.

Important

• This includes covering their nose and mouth when coughing or sneezing, disposing of dirty tissues promptly and carefully, washing hands frequently with soap and water and cleaning surfaces which are regularly touched.
