In the near future there will be bird flu and it is even more dangerous than bird flu and swine flu

Not only do bird flu and swine flu, humans can face even more bird flu.

Until now, pigs and chickens are hosts that contain two types of flu that are the biggest threat to humans. Influenza strains can spread to humans, causing extremely serious consequences.

As for dogs, the types of flu in dogs belong to their own lineage, not from other animals. However, according to a new study, flu viruses start to evolve. They are more and more diverse, and it is very likely that becoming a new pandemic can spread from dog to person.

Even according to experts in New York - where the study is done - the flu will be more dangerous than the other two diseases, because humans are more exposed to dogs.

If there is a flu epidemic spread from dogs to humans, it will be even more dangerous than avian and swine flu.

"Swine flu viruses can spread influenza viruses to poultry and humans," said Adolfo Garcia-Sastre, research author at the Icahn School of Medicine (New York).

"But now, we also see the flu virus can spread from pigs to dogs."

According to Garcia-Sastre, this is when humans need to come up with solutions to prevent the spread of influenza in dogs.

"The United States is not infected with bird flu, because every time it finds out, the number of birds will immediately be destroyed," he said.

In fact, it is not the first time that influenza viruses from other species infect dogs. Since 2003, science has recorded cases of influenza viruses transmitted from horses to dogs. By 2013, some farms in China discovered dogs infected with flu from birds, with H3N2 virus quite dangerous.

"We found a number of groups of viruses from poultry, which can now be transmitted to dogs, and combined with viruses that are only found in dogs," he said.

" H1N1, H3N2, and H3N8 are the three flu viruses that appear on dogs. They are already reacting."

This is when humans need to come up with a solution to prevent the spread of influenza in dogs.

Why can flu viruses spread so strongly?

For those who do not know, a virus itself cannot be spread from one species to another. But moving on, they will receive other viral sequences on each individual, absorb and produce viruses with new genetic properties.

Then when they are strong enough to spread from animals to humans, that's when the disease will happen. More importantly, due to the unprecedented exposure to the virus, the human immune system cannot resist.

Viruses can evolve very quickly.

For example, the 2009 H1N1 flu pandemic is originally from poultry. The virus enters the body of pigs, exchanges genes with some other swine flu, and then develops and possesses the ability to infect humans.

Particularly for dogs, they are inherently resistant to influenza A viruses, often only with viruses with very low ability to spread to humans. But through research, Dr. Garcia-Sastre has confirmed up to 16 types of influenza viruses in dogs in southern China.

Even the H1N1 virus is associated with H3N2 to form three mutant viruses, H1N1r, H1N2r, and H3N2r.

"These new viruses are originally H1N1, but they are different from H1N1 in swine disease, and also different from H1N1 in humans," said Dr. Garcia-Sastre. This means, a new pandemic may occur, with the host being a dog.

It is possible to have a new pandemic flu, with a dog as a host.

Of course, this conclusion still needs a lot of research to get accurate conclusions. But Garcia-Sastre thinks we have to be realistic, and we need to find suitable vaccines before it's too late.
