00:00The recent outbreak of the flu in the U.S. continues to worsen.
00:02Will humans win the global pandemic?
00:05Officials in California have declared an emergency
00:08over the rapid spread of bird flu in livestock.
00:11The first ever bird flu death in the U.S. was reported in Louisiana.
00:15State officials say the patient was over 65 years old.
00:18The CDC says this case is severe,
00:21so much so the person is hospitalized in critical condition.
00:25Is the Pandemic 2.0 coming soon?
00:27A well-known magazine called Nature has recently announced
00:30that the risk of bird flu spreading among humans is increasing.
00:36Scientists warn that once the virus has the ability to infect humans,
00:40humans may welcome the next global pandemic.
00:43Is it time for a storm?
00:46The virus has infected more than 900 herds and 67 people in the U.S.,
00:53killing one individual.
00:55The experts in the Times article said that
00:57while a human pandemic is not inevitable,
01:00some developments indicate that the possibility may no longer be quite so remote.
01:07Although experts believe that the pandemic has not yet settled,
01:10the Nature article's analysis has raised a more worrying trend.
01:14Because the H5N1 virus is mutating,
01:17it may evolve in the direction it can spread among humans.
01:20The article said that although most infections are mild,
01:23the H5N1 virus has already found new mutants that adapt to mammals and pigs.
01:29Especially when the virus is transmitted to humans directly from the vagina during contact,
01:34it may cause serious illness or even death.
01:37The virus scientist at Emory University,
01:38Rakh Davala, warned that if the virus continues to mutate,
01:42it may increase the risk of spreading among humans.
01:45Especially in the past few months,
01:46there have been more and more serious cases.
01:48The New York Times reported on Monday
01:50that there was also a report on whether the flu virus could become air-transmitted.
01:54It showed that scientists are currently studying whether the flu virus
01:59could be transmitted in the same way after the COVID-19 air-transmission.
02:04Researchers are worried that if the flu virus is ignored,
02:07it will cause more infections.
02:09There is also a point worth paying attention to.
02:10A Dutch virologist and his team found that
02:13the H5N1 virus, which has undergone a specific mutation,
02:16can be air-transmitted between the blood cells.
02:18The blood cells are animal models commonly used in flu research.
02:21Its transmission method is similar to that of humans,
02:24so it causes concerns about human-to-human transmission.
02:26Nevertheless, most cases of human infection
02:29are due to contact with infected birds or cows,
02:32not human-to-human transmission.
02:34It's not circulating in humans,
02:35but it is jumping into humans who are exposed,
02:38particularly those exposed to poultry or to the dairy cattle,
02:42the two sort of groups where we're seeing most of the movement
02:45from animal to human,
02:47but we're not seeing sustained circulation.
02:49So every time a person comes in contact with this virus
02:53or gets infected with the virus,
02:55there is that small possibility that there could be a genetic mutation
02:59that would then allow the virus to be transmitted person-to-person.
03:02That risk is really, really low.
03:04It's a relief to hear that.
03:07There is no evidence yet that the H5N1 virus can be air-transmitted.
03:10However, if humans come in contact with infected poultry or cattle,
03:14the risk of infection is still very high.
03:16And the H5N1 air-transmission is definitely not complete.
03:19Its mortality rate is very high.
03:20Since 2013,
03:22nearly 900 cases of H5N1 have been reported worldwide.
03:26About 60% of them died,
03:29which is much higher than the mortality rate of 0.1% of normal air-transmission.
03:33At present, the scientific community is still highly vigilant
03:35against the mutation of the H5N1 virus.
03:37If the H5N1 mutated virus
03:39repeats the evolution of the H5N1 virus,
03:41with the ability to air-transmit person-to-person,
03:43perhaps the world will welcome the 2.0 version of the H5N1 epidemic.
