The WHO has sent a team of international experts to China to investigate the situation, including Clifford Lane, Clinical Director at the US National Institutes of Health. Here is the
press conference on Youtube and the
final report of the commission as PDF after they visited Beijing, Wuhan, Shenzhen, Guangzhou and Chengdu. Here are some interesting facts about Covid that I have not yet read in the media:
- When a cluster of several infected people occurred in China, it was most often (78-85%) caused by an infection within the family by droplets and other carriers of infection in close contact with an infected person. Transmission by fine aerosols in the air over long distances is not one of the main causes of spread. Most of the 2,055 infected hospital workers were either infected at home or in the early phase of the outbreak in Wuhan when hospital safeguards were not raised yet.
- The new virus is genetically 96% identical to a known coronavirus in bats and 86-92% identical to a coronavirus in pangolin. Therefore, the transmission of a mutated virus from animals to humans is the most likely cause of the appearance of the new virus.
- China can now produce 1.6 million test kits for the novel coronavirus per week. The test delivers a result on the same day. Across the country, anyone who goes to the doctor with a fever is screened for the virus: In Guangdong province, far from Wuhan, 320,000 people have been tested, and 0.14% of those were positive for the virus.
- The vast majority of those infected sooner or later develop symptoms. Cases of people in whom the virus has been detected and who do not have symptoms at that time are rare - and most of them fall ill in the next few days.
- The most common symptoms are fever (88%) and dry cough (68%). Exhaustion (38%), expectoration of mucus when coughing (33%), shortness of breath (18%), sore throat (14%), headaches (14%), muscle aches (14%), chills (11%) are also common. Less frequent are nausea and vomiting (5%), stuffy nose (5%) and diarrhoea (4%). Running nose is not a symptom of Covid.
- An examination of
44,672 infected people in China showed a fatality rate of 3.4%. Fatality is strongly influenced by age, pre-existing conditions, gender, and especially the response of the health care system. All fatality figures reflect the state of affairs in China up to 17 February, and everything could be quite different in the future elsewhere.
- Healthcare system: 20% of infected people in China needed hospital treatment for weeks. China has hospital beds to
treat 0.4% of the population at the same time - other developed countries
have between 0.1% and 1.3% and most of these beds are already occupied with people who have other diseases. The most important thing is firstly to aggressively contain the spread of the virus in order to keep the number of seriously ill Covid patients low and secondly to increase the number of beds (including material and personnel) until there is enough for the seriously ill. China also tested various treatment methods for the unknown disease and the most successful ones were implemented nationwide. Thanks to this response, the fatality rate in China is now lower than a month ago.
- Pre-existing conditions: The fatality rate for those infected with pre-existing cardiovascular disease in China was 13.2%. It was 9.2% for those infected with high blood sugar levels (uncontrolled diabetes), 8.4% for high blood pressure, 8% for chronic respiratory diseases and 7.6% for cancer. Infected persons without a relevant previous illness died in 1.4% of cases.
