CDC experts say that China’s lack of data on the Wuhan coronavirus limits international efforts to quench the outbreak.
Although the consultants commended Chinese researchers in just a few weeks ‘ time to map the genome of the virus, there was clearly a lack of epidemiological evidence as to who is infected by the virus and how the virus spreads.
“It is Epi 101,” said Dr. William Schaffner, medical director of the National Infectious Diseases Foundation and a long-standing CDC consultant.

On 31 December the first cases were reported to the World Health Organization, with 44 cases in China by 3 January. Currently, not even three weeks later, over 600 cases have occurred, and the epidemic has spread to Thailand, South Korea, Japan, Singapore, Saudi Arabia and the USA, where there is only one case.
As no vaccine is available against this new virus, the advice of the CDC indicated that public health measures such as early capture cases and quarantine rules are important. Yet they agree it is difficult to know who can be quarantined, and how long without understanding how infected people are, how long they are able to spread the virus to others.
“This knowledge is extremely important. It shows you how to treat an outbreak and what you should look for and who to think about,” said Dr. Paul Offit, a specialist in pediatric infectious diseases at the University of Pennsylvania’s Perelman School of Medicine and a longtime CDC advisor.
Disease detectives searching for more details on Wuhan Coronavirus’s’ super spreading tools ‘ Disease detectives search for more information regarding Wuhan coronavel virus’s’ super spreader’ At a press conference on Wednesday in Beijing, Li Bin, the Chinese Vice Minister of National Health, said his country is’ engaged’ in the public and international disclosure of information
On Thursday, Chinese authorities provided new epidemiological information to top officials from the World Health Organization, which reported a growing number of cases, suspected cases, the affected Provinces and the proportion of fatalities. They have reported cases of the fourth generation in Wuhan— which means that a person infected can give the virus to a third person who can give it to a fourth person. According to a WHO media release, they reported second-generation cases outside Wuhan, and also clusters outside Hubei province.
But the advisors of the CDC said that wasn’t almost enough. They said that there are still very specific pieces of information missing on the spread of the Wuhan coronavirus.
Of these: how many of the 600 cases were contracted by the virus from the handling of animals on the farm where that virus emerged and how many were contracted by people on the street?
Were they family members of people who are sick on the street or colleagues sitting beside each other at work, among those who never went to the market? Or perhaps they don’t know anyone who is sick, and where they caught it isn’t clear?
Looking at the chain of infection, do people spread the disease before they have symptoms or are they recovering?

Patricia Stinchfield, Vice President of the National Foundation for Infectious Diseases and CDC Advisor said “You have to consider how this is spreading.

How many people are hospitalised?

How about Coronavirus do you need to know?
02:29 A CDC spokesman declined to comment on the story.
A WHO official has said he acknowledges the frustration of a lack of epidemiological knowledge, but it is likely that some CDC workers know the answers and have not yet transmitted them to the public or advisors.
At the start of the outbreak, Dr. David Heymann, Chair of the WHO Infectious Risk Strategic and Technical Advisory Group, said that sometimes different groups know different pieces of information.
“The CDC may have access to WHO-free information, and vice versa,” he said.
Generally speaking, the more detail public health officials learn, the better.
“The more you learn, the more you can identify and control what the problem is,” he said.
