From the avian flu to the swine flu
Before we continue, we will see a video. This video helps us to better position ourselves between the avian flu of 2003 and the current swine flu.
In 2003, a similar variant of the flu virus appeared in poultry farms in Southeast Asia. The H5N1 virus filled the lungs of birds with fluid and killed them. Over the next two years, the virus was transmitted 50 times from birds to humans, and 30 of these people died. Since then, the World Health Organization estimates that 275 people have died from avian influenza. Scientists and
health authorities around the world were alerted to the potential risk of a pandemic. But in order for the virus to spread and reach a large part of the population, it had to be transmitted from person to person, and to do so, it had to undergo a mutation. In the end, none of this happened.
At the end of last week, the World Health Organization warned of an outbreak of swine flu in Mexico. Behind it is a virus with a name similar to the previous one: The H1N1. Such a rapid spread suggests that in this case it is being transmitted between humans, but the exact number of patients and how they have contracted the virus is still unknown.
