On March 13, 2020, Patrick Valence, the chief scientific adviser of the British government, said that about 60% of the British population would need to be infected with the novel coronavirus to obtain “group immunity” in the whole country. This caused a lot of controversy in the world.
What is Group Immunity? Group immunity (Herd immunity) refers to the resistance of populations or animal groups to infection. A high level of group immunity indicates that the percentage of animals in the group that are resistant to infection is high.
China’s latest discovery of novel coronavirus warns that Coronavirus is mutating which would discourage vaccine development.
Chinese scientists warn that the mutations of coronavirus may be underestimated by them because the latest deadliest strains control Europe and the United States.
Chinese scientists have discovered that the east coast of Europe and America has been infected with one of the most aggressive coronavirus strains because dozens of viral mutations of coronavirus have been found.
From cytokine storm to honeycomb lung, study the whole onset process of Coronavirus infection, wen could find that the novel Coronavirus will not just damage the lungs only in human body. The novel coronavirus has many same characteristics as SARS and MERS. The coronaviruses can induce reactions in multiple organs, which is also a typical characteristic of zoonotic coronaviruses.
Per to current world wide situation of coronavirus, the virus has a very fast spread rate.
After a several weeks’ lockdown, people are going to lose the patient keeping staying at home. It bring a boring live with huge disruption, distress and stress to lives in the world. So, when UK government decided to extend the lockdown to more three weeks, many people can not help to have a question in mind when the outbreak will end, and when to lift the lockdown, and when the life would get back to normal.
The deaths of Coronavirus in the world is a big number, and the death rate is about 6.9%. The good is the recovered number is much more, and the recovered rate is more than 25%. Since there were many recovered cases which were tested Positive again in few days later after recovered. People may have questions if there is any sequela of Coronavirus to those recovered cases? Here just collect some opinions from medical experts.
The world confirmed cases increase to 2,310,572 untill 18th of April in almost 210 countries and regions. Really a serious situation to the government of those countries. However, we still see lots of people going out without face mask, and every day the heads of government speak in the press conference without mask. So, why do they not ware a mask in such a situation of Coronavirus? They are super man or stupid?
17th, WHO issued a warning at a press conference, saying that there is no evidence that new coronavirus patients with new coronavirus antibodies in the blood and patients with asymptomatic infection have long-term immunity to the new coronavirus. Some officials said that at present, it is impossible to determine that people with antibodies can be fully protected from illness.
According to Forbes News and CNBC website reports, WHO experts said that the new coronavirus serum test (also called antibody test) can indeed show whether a person has been infected with the virus in the past, but there is no evidence that the test can prove whether a person has Immunity, or there is no longer any risk of reinfection.
The latest Coronavirus confirmed grow up to 2,256,844 in the world, and deaths goes to 154,350. And in US, the confirmed increased a lot to 712,184 till 18th, April. And the number is increasing a lot every day. Even though Trump announced the “3-steps” reopen plan, no one knows when epidemic will end. Coronavirus has been confirmed in more than 210 countries and regions. It is a global panic to the world.
People in many countries now have a long time staying at home for the city/country lockdown policy, apart from those countries with “Immunotherapy” facing Coronavirus pandemic. Anyway, it is difficult to say “Immunotherapy” is right or not, but definitely the deaths will be a big number with “Immunotherapy”. According the latest research from USA, for Coronavirus(COVID-19), at least 82% people in the country have to be infected with “Immunotherapy”, then it could be safe.
The coronavirus epidemic began to spread gradually in world, first China, Italy, Spain, UK, France, Germany, Europe, and then Canada, USA. And Until now, the total confirmed cases in the world climbed to more than 2 million, and confirmed deaths increased to 134 thousand which is terrible, and seems to be more terrible in several days. In this case, many country governments issued and started the “Stay-at-Home” policy, requesting people to stay at home to prevent the spread of the coronavirus (COVID-19).
