Brief Difference between Nucleic Acid Test kit and Antibody Test Kit.
Nucleic Acid Test Kit What is Nucleic Acid Test (NAT) and how it works may be find in this article: What is Nucleic Acid Detection?. In this article, just compare the difference of Nucleic Acid Test and Antibody Test.
Nucleic Acid Test currently is the main diagnostic test method to check and confirm the suspected Coronavirus patients, because it has strong specificity and relatively high sensitivity by detecting the existence of the viral nucleic acid in our collected specimen directly.
Recently, some governments suggested that the detection of antibodies to the Coronavirus (COVID-19), could be taken as an “immunity passport” or “risk-free certificate”. In this case, those with COVID-19 antibody could be able to travel or to return to work with the assumption that they are protected against re-infection. And this also is the basis of “Group Immunity” strategy in some Europe countries. There is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from re-infection.
“It is a target, and, obviously, we’re hopeful about that target, but I think it’s just too early to be able to tell that we see light at the end of the tunnel,” Food and Drug Administration Commissioner Stephen Hahn said on ABC News’s “This Week”. Last week, what as discussed most is the president Trump’s decision of Reopening economy and Returning to work by lift lockdown policy progressively. Is whole USA ready?
Coronavirus has been the hottest topic of the world now. The confirmed number and deaths are keep growing up, and every one is waiting the peak coming. But when, no one knows. At least, from the statistics the growth rate is not getting slower.
In this case, many people may have doubts why China could contain and suppress Coronavirus so quickly in a short time, clean the cases to zero and lift the lockdown soon.
WHO recently led to establish a global vaccine research team composed of scientists, doctors, funders and manufacturers. The WHO statement stated that this would help reduce inefficiency and duplication of labor. Earlier, the document issued by the WHO on April 11 stated that there were three vaccines that had entered clinical trials globally. There are 67 vaccines that have not yet entered clinical trials.
According to the State Council of China, China is researching and developing in five technical directions including inactivated vaccines, genetically engineered recombinant subunit vaccines, adenovirus vector vaccines, attenuated influenza virus vector vaccines, and nucleic acid vaccines.
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.
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?
