Recently, local epidemics caused by Omicron mutant have appeared in several provinces of China. In the face of the threatening Omicron mutant, we should know ourselves and fight every battle. Omicron is a mutant of novel coronavirus. After being infected with Omicron, there will be individual differences in symptoms. So how long can Omicron survive at room temperature? How many days can Omicron be detected? Let me talk about it.

According to the research of Japanese kyoto prefectural university of medicine researchers, we can draw the following conclusions:

The results showed that on the plastic surface at room temperature, COVID-19 original virus could survive for 56 hours, Delta strain could survive for 1 14 hours, and Omicron mutant strain could survive for 193.5 hours. In addition, compared with other early COVID-19 mutants, Omicron survived longer on human skin, so Omicron survived longer on the skin surface than Omicron.

There are indications that the evolution of Omicrovirus has broken the bottom line. In order to spread more widely, it has been upgraded to adapt to more living environments, including long-term survival at room temperature.

How many days can Omicron be detected?

Most patients can be detected within 3~7 days. COVID-19 Omicron has a strong transmission ability. After being infected with Omicron, the virus will lurk in the body for a period of time, but it cannot be detected by nucleic acid detection during the incubation period, because the viral load is relatively low at this time.

Generally, Omicron infection can be detected in most patients 3~7 days after infection, because Omicron will replicate in the body and be detected when it reaches a certain level, but it does not rule out that some patients are physically strong and the incubation period will be longer, so it takes longer and more nucleic acid detection to be detected.

? So how do we ordinary people judge whether we have Omicron or not? What are the common symptoms of Omicron that we need to know?

Cough, dry cough, burning sensation in the lungs, fatigue, drowsiness, stuffy nose and runny nose, headache, fever, sore throat, stuffy nose and runny nose, cough, scanty phlegm and white phlegm.

The symptoms of children infected with Omicron are more similar to the flu. According to the report of American Academy of Pediatrics, the common symptoms of children are as follows:

Have a dog's barking cough (similar to growling), dyspnea, hoarseness, slight sore throat, runny nose or stuffy nose, and fever.

How can the public guard against Omicron mutants?

Maintain good personal hygiene habits. Pay attention to hand hygiene, wear a mask scientifically, ventilate frequently, gather less, keep a "one-meter line", and cover it with a paper towel or elbow when coughing or sneezing.

2. Improve immunity. Reasonable diet, moderate exercise and adequate sleep.

3. When receiving the courier, reduce direct contact with the courier packaging. Buy cold chain food from abroad, and disinfect the express delivery by foreign postal parcels. Personal protection should be done before taking the courier, wearing masks and gloves correctly, washing hands as soon as you take the courier, and avoiding touching other items.

4. Reduce unnecessary going out. We should try to avoid going to high-risk areas and crowded places, strengthen personal protection when going out, and reduce the chance of infection with Omicron variants.

5. People who have recently lived in epidemic-related areas, crossed the case track and received health warning messages and abnormal health codes should take the initiative to report to their communities, hotels and work units, do a good job of personal protection, try to avoid taking public transport, and go to nearby nucleic acid detection points for nucleic acid detection as soon as possible.
