Featured below is an interactive Google map pinpointing outbreaks of H1N1 swine flu in 2009,
together with source attributions, report dates, and current known
statuses. This map is updated throughout the day with the latest
suspected and confirmed cases of swine flu,
as reports come in. Please note that this swine flu map is not owned or

How to use the H1N1 map
You can zoom in and out and scroll around to view any country that you like, or any region that you like. To view information on a specific case, simply click on a map marker. Due to the amount of H1N1 cases, some content appears hidden until you zoom in to a specific map area.

Swine flu (swine influenza) is a disease of pigs. It is a highly contagious respiratory disease caused by one of many Influenza A viruses. Approximately 1% to 4% of pigs that get swine flu die from it. It is spread among pigs by direct and indirect contact, aerosols, and from pigs that are infected but do not have symptoms. In many parts of the world pigs are vaccinated against swine flu.
Most commonly, swine flu is of the H1N1 influenza subtype. However, they can sometimes come from the other types, such as H1N2, H3N1, and H3N2.
The current outbreak of swine flu that has infected humans is of the H1N1 type - this type is not as dangerous as some others.
It is possible for pigs to be infected with more than one flu virus subtype simultaneously. When this happens the genes of the viruses have the opportunity to mingle. When different flu subtypes mix they can create a new virus which contains the genes from several sources - a reassortant virus.
Although swine influenza tends to just infect pigs, they can, and sometimes do, jump the species barrier and infect humans.
As swine flu symptoms are similar to typical human seasonal flu symptoms, and other upper respiratory tract infections, detection of swine flu in humans often does not happen, and when it does it is usually purely by chance through seasonal influenza surveillance. If symptoms are mild it is extremely unlikely that any connection to swine influenza is found - even if it is there. In other words, unless the doctors and experts are specifically looking for swine flu, it is rarely detected. Because of this, we really do not know what the true human infection rate is.

What is Swine Flu?
Swine flu (swine influenza) is a disease of pigs. It is a highly contagious respiratory disease caused by one of many Influenza A viruses. Approximately 1% to 4% of pigs that get swine flu die from it. It is spread among pigs by direct and indirect contact, aerosols, and from pigs that are infected but do not have symptoms.

The current outbreak of swine flu that has infected humans is of the H1N1 type - this type is not as dangerous as some others.
Avian Influenza (Bird Flu) can also infect pigs
Avian flu and human seasonal flu viruses can infect pigs, as well as swine influenza. The H3N2 influenza virus subtype, a virulent one, is thought to have come from pigs - it went on to infect humans.It is possible for pigs to be infected with more than one flu virus subtype simultaneously. When this happens the genes of the viruses have the opportunity to mingle. When different flu subtypes mix they can create a new virus which contains the genes from several sources - a reassortant virus.
Although swine influenza tends to just infect pigs, they can, and sometimes do, jump the species barrier and infect humans.
What is the risk for human health?
Outbreaks of human infection from a virus which came from pigs (swine influenza) do happen and are sometimes reported. Symptoms will generally be similar to seasonal human influenzas - this can range from mild or no symptoms at all, to severe and possibly fatal pneumonia.As swine flu symptoms are similar to typical human seasonal flu symptoms, and other upper respiratory tract infections, detection of swine flu in humans often does not happen, and when it does it is usually purely by chance through seasonal influenza surveillance. If symptoms are mild it is extremely unlikely that any connection to swine influenza is found - even if it is there.
