Symptoms of having Omicron Strain include muscle aches, body fatigue, fever, cough, sore throat, or no symptoms at all. Currently, most patients infected with the omicron strain only experience mild symptoms of infection, mainly muscle aches, body fatigue, mild cough, etc. Some patients may experience symptoms such as hoarseness of the throat, headache, fever, etc. Symptoms such as loss of taste and smell are less frequent, and some infected people do not show any symptoms. Omicron is a mutated strain of Neocoronavirus with more mutations of the spiny proteins, which can easily infect human cell receptors, so its infectious ability has been greatly enhanced compared to previous mutated strains. Moreover, it is found that the Omicronavirus strain has a triple mutation of the s-protein, which has a greater increase in immune escape ability, and this may reduce the protective effect of the Neocoronavirus vaccine. If your body develops symptoms of cough or fever, or if you suspect that you are infected with the Omicron strain, it is important to visit a hospital in time to complete the New Crown nucleic acid test to make a clear diagnosis, so as to avoid delays in the disease and the spread of the virus. Need to actively prevent omicron strain infection, do a good job of their own protection, such as adhering to wear masks in public places, reduce crowd gathering, avoid to medium and high risk areas; daily life to wash hands; adhere to the injection of the new crown virus vaccine, can play a role in preventing infection.
