COVID-19/Coronavirus is the name of the disease, its official Chinese name is “冠狀病毒病 / 新冠肺炎”, which is a new type of coronavirus and the disease it causes; while SARS-CoV-2 is the name of the virus, which is severe acute respiratory syndrome Coronavirus. People often know the name of a disease, but not the virus that causes it.

Viruses and the diseases they cause often go by different names because they have different processes and purposes. Viruses are named according to their genetic structure to facilitate the development of diagnostic tests, vaccines and drugs, and virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV). Diseases are named to discuss prevention, transmission, contagiousness, severity and treatment of diseases. The prevention and response of human diseases is the responsibility of WHO, so diseases are officially named by WHO in the International Classification of Diseases (ICD).

ICTV announced on February 11, 2020, “Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)” as the name of the new virus, chosen because of its connection to the virus that caused the 2003 SARS outbreak. Coronaviruses are genetically related, and while related, the two viruses are different. On 11 February 2020, WHO announced “COVID-19” as the name for the new disease, based on previous guidance developed with the World Organization for Animal Health (OIE) and the Food and Agriculture Organization of the United Nations (FAO).

According to WHO statistics, about 80% of patients with new coronary pneumonia are mild or asymptomatic, and only 15% are severe. 2. Patients with new coronary pneumonia usually have low blood oxygen. If there is no difficulty in breathing, it is easy to be despised or delay medical treatment. Therefore, it is very important to self-monitor the “blood oxygen concentration” to know the condition of the disease.

We can use Oximeter to check the “blood oxygen concentration”. The price of the Oximeter varies according to its sensitivity, accuracy and other auxiliary functions. Generally, the price of Oximeter ranges from a few hundred Hong Kong dollars to more than a thousand Hong Kong dollars. In the detection of blood oxygen concentration, the normal value of blood oxygen saturation for the average person is above 95%, and if it is lower than 95%, there is hypoxia. Consider seeking medical treatment. If you miss the golden period of treatment, when blood oxygen is lower than 90%, the patient will be There is a risk of death, and the response to treatment at this time is also relatively poor, so pay attention to physical abnormalities in time. In addition to COVID-19, blood oxygen can also be used for other issues, such as monitoring blood oxygen to assess the state of sleep apnea patients and high mountain exercisers, monitoring the state of the heart with blood flow, and measuring blood flow in the left and right hand’s fingers which oxygen status may reflect arm pain caused by vascular obstruction in arm muscles and joints.
