WHO said that the new NCOV strains recorded in Vietnam are not hybrid, but experts think this is still a great risk.

Various strains from the same type of virus can exchange genetic material in the host body and create new strains spread to other hosts.

NGUYEN THANH LONG HEALTH MINISTER on May 29, on May 29, notified a new strain including structures from India and from the UK, on some patients in the epidemic.

The Ministry of Health identifies the infection of this strain of virus only 1-2 days, ie after every day has a File of Fore.

Dr. Kidong Park, Chief Representative of the World Health Organization (WHO) in Vietnam, on June 3, said the NCOV strain was not hybrid, but still in Indian strain B.1.617.2.

Todd Pollack, specialist in transmission disease at Harvard Medical University, said that many mutations still appear during the spread of the virus and most are not worrisome on the clinical aspect.

If the new strain has the characteristics of some other strains, this does not necessarily mean older strains and infections in a patient and produce a combined suppression.

Fidler experts share with views.

Countries that lack vaccine are more drastic in hope to quickly cut infectious strings and prevent new mutations.

Experts have repeatedly warning mutations in NCOV will make the wave of daily epidemics, due to evolutionary viruses and seeking to spreading more efficiently in the population formed community immune, albeit with vaccine

WHO also forecast NCOV will continue to generate many other strains in the process of spreading and evolution.

According to Fidler, the danger of the new strain depends on the two main factors.

In countries that have been under pressure because of the original virus strain and have not accessed the vaccine, the NCOV strain only needs higher infections than sufficiently hazardous because the burden that the health system and the economy suffered,

India and the UK are typical examples, indicating that water has a developed economy and owns the technology of vaccine production still faces many difficulties when facing new strains.

At the peak translation stage in January, he recorded more than 4,500 hospitalizations for Covid-19 in a day.

Clinical microorganisms Ravi Gupta, Cambridge University, concerning the perspective of survive virus strains appear in the future.

The fact that the virus is always evolved to spread easier in the community, while the virus strain causes Covid-19 pandemic which is generally unpredictable and countries should not be subjective at any stage.

We have owned many good vaccines.

I believe they will re-synthesize and we will face super-mutant viruses, Gupta said.

According to Gupta, with Vaccine Covid-19, most people infected with NCOV strains, despite a new mutation, only have symptoms not too serious.

According to David Fidler, increasing the US global vaccine supply and European countries still stopped in limited quantities.

We still haven't grasped exactly when countries who are very needed to access the vaccine, how long it takes to take these countries to turn enough to turn the situation before Covid-19 and new strains, Mr. Liu

He also said that technology transfer and knowledge of vaccines from the US is not a short-term solution for low-income countries and medium from new strains.

The process of conversion of knowledge into vaccines cannot take place quickly.
