In fact, COVID-19 cases in the United States are more than 90% who have not received any virus tests. The main reason is that nucleic acid detection and antibody detection can not provide fast and accurate COVID-19 detection results in the early stage of virus infection.

The number of infections in South Africa has been reduced by 30% First of all, in South Africa, where the Omicron variant was first discovered, the epidemic seems to have passed an inflection point.

Henan UDX Biotechnology Co, Ltd is a professional high-tech biotechnology company who is engaged in R&D, manufacturing and marketing for medical in-vitro diagnostic(IVD) rapid test kits, like covid-19 antigen rapid test kit, covid-19 Ig/G, Ig/M rapid test kit, total antibodies rapid test kit and covid-19 antigen&saliva rapid test kit and so on.

Saliva samples: IVD classification terms and rules. Detect whether there are or reveal infectious agents, which can cause life-threatening diseases and have a high or suspicious transmission risk.

Flu season is starting in many parts of the world now. So, now people are worried about flu and COVID. How worried should people be? What are their risks? I think we shouldn't be worried. We should rather be prepared because for flu, we do have a vaccine, we do have antivirals and a set of measures.

According to CNN, there has been an unprecedented surge in the number of COVID-19 cases caused by the rapidly spreading Omicron variant, which is crushing hospitals across the United States.

First of all, in South Africa, where the Omicron variant was first discovered, the epidemic seems to have passed an inflection point. According to reports, the number of infections in South Africa within 7 days has dropped by 30%, and the average daily death toll has dropped from 65 a week ago to around 50, which is less than one-tenth of the 577 people in South Africa during the second wave of outbreaks in January.

Rapid antibody detection kit: a necessity in epidemic situation. After that, it can stay in the patient's body for several months, and the virus can spread to all parts of the body and continue to attack the heart and brain.

Since the outbreak of COVID-19, virus nucleic acid detection and antibody detection methods have been widely applied, and to a certain extent, contain the spread of the virus. However, according to the disclosure of the CDC at home and abroad, most virus carriers were not identified in time in the early stage of infection.
