The virus hypothesis escape from Wuhan Virus Institute makes experts worry about the biosafety level of global laboratories.

18 months after the outbreak in Wuhan City, China, Covid-19 made more than 171 million people infected globally.

President Joe Biden last week asked the US authorities to investigate NCOV, including a virus hypothesis from Wuhan Laboratory, whether the reports earlier this year of the WHO investigation team said this ability was very difficult

However, we always know a deadly pathogen at risk of doing that, John Simpson, the BBC editor, said.

When the NCOV virus hypothesis escapes from the recent laboratory to be returned to the center of debate, Colonel Hamish de Bretton-Gordon, the famous expert on biological warfare, has called on G7 leaders, the national group

Colonel Bretton-Gordon used to be a commander of his nuclear, radioactive, biological and chemical regimes.

I spent a lot of time of life in places where governments want to harm others.

Two researchers working at the Laboratory of Vu Han Virus Institute in February 2017.

Simpson, the BBC editor, said international control of the dangerous loose-dangerous fabrication and research centers.

Laboratory research on pathogens is often classified according to the risk of biosafety from level 1 to level 4, the highest level.

Porton Down is usually described as a place with gold standards on biosafety and such level 4 laboratories often controlled very strictly.

Most of these do medical research work, but also often keep and test many viruses like Covid-19.

Studies on chemical weapons are better controlled than studies on biological threats.

In fact, in Syria showed that OPCW could not fully extinguish the production and use of chemical weapons, but this organization is still working in and effectively.

Controlling research and manufacturing biological weapons is not strictly controlled.

Colonel Bretton-Gordon hopes the risks from global biological research facilities will become a matter in the agenda at the Summit of G7 leaders in June. He also mobilized

I think almost any US president wants to support this proposal.

In the 2007-2008 period, General Petraeus used to be the commander of the Multinational Forces led by the US in Iraq, the country under Saddam Hussein accused of developing biological and chemical weapons, although not found evidence

For decades, countries have strengthened control of nuclear weapons and then chemical weapons, as well as their production research.

But with 8 million people may have died because of Covid-19, the ability to escape from one of the 3,000 strictly controlled laboratories could make biological threats more dangerous, Simpson warned.
