since the 2009 swine flu pandemic claimed nearly 300,000 lives
It Seems that from 2020 there is good news for us: according to a study in the journal Proceedings of the National Academy of Sciences, China applies new strain of the H1N1 swine flu virus. The virus walks in the world since 2009, became its victims at least 285,000 people. Over time it has become a seasonal flu, but the new strain – G4EA H1N1 was widespread in pig farms of China from 2016 and efficiently replicates in the respiratory tract of a person. So far, the virus has infected mostly working farms, and the disease proceeded in the form of light, but experts fear that the situation may change at any time. The authors note that the spread of the virus is urgently needed to contain it, otherwise the world may face another pandemic.
«Swine flu» — highly contagious (contagious) infectious disease caused by pandemic influenza A(H1N1). The virus is transmitted from pigs to humans and spreads efficiently between people. The symptoms of H1N1 influenza are similar to symptoms of ordinary flu, fever, cough, runny nose, some patients also present vomiting, diarrhea and abdominal pain. In the case of severe disease can be fatal.
«Viruses G4 have all the essential features of a potentially pandemic virus», — the study authors write, Recalling the need for implementation of control over the spread of the virus in pigs and closely monitoring the circulation G4EA H1N1 among people. the Study is based on the observation of pigs in 10 provinces of China from 2011 to 2018. Over the past three years were collected 338 blood samples of workers 15 the pig and the 230 inhabitants of nearby households.

the swine flu Virus affects swine and farm workers
The Results revealed a positive result for antibodies to H1N1 G4EA from 10.4% of workers and 4, 4% of residents near the pig farms. It is noteworthy that the positive test on antibodies the workers aged from 18 to 35 years were found by 20.5% more likely than other age groups and residents of nearby villages. What the consequences of a pandemic we have to face .
Prediction of risk is not an exact science, but you need close attention to the virus. It cannot be excluded that passed between people, G4EA H1N1 could mutate and become more aggressive, as did SARS-CoV-2, causing COVID-19. It is very important study and the virus seems kind of dangerous. We have to worry about any disease that can spread from person to person.

As The New York Times, the study was submitted for review in early December, a few weeks before the outbreak of the coronavirus in the Chinese city of Wuhan made the headlines of the world Newspapers. The next important task of scientists is figuring out, not contracted workers of pig farms from their peers, as well as not spread the virus on family members and neighbors.
The paper also stated that the Eurasian variations of H1N1 have been circulating in pigs in Europe and Asia for decades, however, the strain G4 have grown on Chinese farms pigs with respiratory symptoms were found more often after 2014. New data indicate that the H1N1 virus G4EA is a growing problem on pig farms, and the widespread circulation of strain G4 in pigs inevitably increases the exposure of viral particles per person.

The Study was conducted in cooperation with governmental agencies of China, including researchers from the Center for control and prevention of diseases (CDC), experts from the world health organization (who) and scientists from several universities of China and the University of Nottingham in the UK.
The H1N1 Virus pandemic, which erupted in 2009 had relatively low mortality rate, experts estimate it to 0.02 percent. For comparison, the mortality from the influenza pandemic of 1918, researchers estimate 2.5% of the total number of victims. However, the Spanish flu killed an estimated 50 million, and maybe more, as the virus has infected a huge number of people and spread at a time when medical care was much less effective.

Definition of mortality from the new coronavirus is a key issue for epidemiologists, but they will not be able to answer it until then, until the pandemic is not over.
