An article published in Nature Medicine in 2015 with a co-author from Wuhan institute.
If you read the abstract it says they have assembled a virus in the lab that can transmit from bats to humans.
Remember that time when a virus escaped from a Chinese lab...
The 1977 H1N1 human influenza pandemic
Due to lab mishandling, a strain of the H1N1 influenza managed to escape from a Chinese facility that was likely trying to create a vaccine for the disease. The virus spread globally and had an infection rate of 20% to 70% among those exposed. Luckily, the strain of the virus caused only mild disease and few fatalities.
Various SARS outbreaks
Severe Acute Respiratory Syndrome (SARS) was a global epidemic in 2003 that caused 8,000 infections and 774 deaths across 29 countries.
Since the original epidemic, there have been six escapes of the virus from laboratories — four in Beijing, and an additional one each in Singapore and Taiwan.
In all cases, the virus escaped due to negligence and human error. Fortunately, none of those escapes led to a renewed outbreak.
Outside China too!
The 2007 Foot and Mouth (FMD) outbreak in the UKFMD is a highly transmissible disease that infects cloven-hoofed animals. Outbreaks of the disease can cause billions of dollars in economic damage as millions of animals may need to be culled to limit the disease's spread. In 2007, 278 animals in the UK became infected with FMD after the virus escaped from a biosafety lab four kilometers away. The outbreak required 1,578 animals to be culled and cost an estimated 200 million pounds.
Smallpox outbreaks in Great Britain
From 1963 to 1978, there were three smallpox escapes from two different laboratories. All three were due to poor standards and bad practices within the labs. Three cases and at least 80 deaths were linked to the outbreaks.
The 1995 Venezuelan equine encephalitis (VEE) outbreak
In 1995, 10,000 people in Venezuela and 75,000 people in Colombia fell ill with a VEE strain that had escaped from a lab. The outbreak caused upwards of 311 deaths and 3,000 cases of neurological complications.
Then there's Russia...
2000 - RussiaSmallpox infected 8 young children in Vladivostock who had played with discarded ampoules of smallpox vaccine has now been confirmed by the Ministry of Health of the Russian Federation. Smallpox Russia
Just last year a lab explosion tore through a Russian bioweapons lab that stores Smallpox, Ebola and other nasty things.
1970 The Aral smallpox incident was a July 30, 1971 outbreak of the viral disease which occurred as a result of a field test at a Soviet biological weapons facility on an island in the Aral Sea. The incident sickened ten people, of whom three died, and came to widespread public notice only in 2002.
