How to protect yourself from the flu pandemic
The world is facing a flu pandemics that will last for years and cost trillions of dollars.
But, experts say the US and its allies need to start preparing for a new pandemic sooner rather than later.
Here’s what you need to know.
What are the flu strains?
There are more than 1,000 different types of influenza.
The most common strains are seasonal, but there are also new strains in developing countries as well.
They include H5N1, H7N9 and H7S1, which have the potential to kill up to 90% of people.
The US and Australia have the most severe strains, but other countries, including Canada and New Zealand, are not as affected.
The most common seasonal flu strain in the US is the H5NP1.
This strain has killed at least 20 people.
It is spread by close contact with infected people and has caused severe illness in a large number of people, including babies and young children.
H5N2, the most common strain in Australia, has killed up to 50 people and is spread mostly by people living in close quarters with the virus.
It also causes severe illness, and can lead to death.
There are also other strains, such as H7F, which are more prevalent in the tropics and can kill up, say experts.
H7N2 is also spread mainly by people who have close contact in areas where the virus is circulating.
It can lead directly to death, and also can lead people to believe that they are under quarantine.
H8N1 is spread more easily in the Americas and Europe, where there is more virus in the air and people have a higher immunity.
H8N2 can also cause severe illness and death.
H9N2 and H9N3 are both spread more frequently in the Middle East, Africa and Asia.
They are also spread by people in close contact, and are more difficult to control.
H1N1 and H1N2 are both more common in Australia and the Americas.
H3N2 has been around for more than 20 years and is one of the more common strains in the developing world.
It causes mild illness and sometimes death.
The H5 strain, which causes severe flu, is spread mainly through close contact and is rarely spread from person to person.
H4N1 or H4N2V are both very rare in the developed world.
H6N1 can be passed to people through contaminated needles.
H2N1 causes mild or moderate illness, although it is much more deadly than H2N2.
H11, H12, H13 and H14 are among the most commonly found strains in Australia.
They can cause severe illnesses, sometimes death, but can also be fatal in very large numbers.
H16, H17, H18 and H19 are also the most prevalent strains in Africa and are spread by direct contact.
H10 and H11 are the most frequent and deadly strains in Asia.
H13 is also found in some parts of Africa and is found in close-quarters with infected persons.
H17 is the most deadly strain in Africa.
It may cause death in up to 60% of the people.
H19 is found only in Europe, the Middle Eastern, Asia and North America.
The majority of strains in these regions are very deadly.
The pandemic has killed more than 3.4 million people worldwide, most of them in the three main regions: Asia, the Americas, and Europe.
There have been no cases of influenza in Australia since the pandemic began in March, but the number of confirmed cases of flu is rising steadily.
According to figures released on Tuesday by the World Health Organization (WHO), more than 2.4m Australians are now infected with the H1 and the H2 viruses, with the number now at over 2 million.
However, there have been a number of deaths and a number fewer cases of H1/H2.
In March, WHO said more than 7,000 Australians died from the H3 strain.
The latest figures put the death toll at 8,851.
The total number of H3 cases in Australia is now over 5,000.
