Does cold and fever have an effect when detecting nucleic acid?
Generally, it won't have much impact.
Nucleic acid detection is mainly to judge whether there is a gene fragment of COVID-19 by detecting the DNA or RNA sequence of COVID-19, which has certain specificity. So if it's just a common cold and fever, it won't have much impact on the nucleic acid test results, so don't worry too much.
However, since one of the symptoms of COVID-19's infection is also a cold and fever, it is suggested that it is best to report to the relevant community before doing nucleic acid testing, and then do personal epidemiological investigation.
Centralized nucleic acid detection of cross infection.
Normally, not.
Cross infection generally refers to the repeated use of medical consumables, such as infusion needles, cotton swabs or medicine bottles, to bring the virus into healthy people.
In the process of centralized detection of nucleic acid, the sampling tools, test tubes and other testing supplies used are disposable, and the relevant medical staff have received formal training. Generally, there will be no cross infection. It is suggested that the sampled personnel wear masks when queuing, queue every one meter, actively cooperate with the medical staff to sample as soon as possible, and leave the scene quickly after sampling.
Can I travel if the results don't come out after centralized nucleic acid testing?
It depends.
If it is only a general screening for the general population, as long as their health code and travel code are green, it will generally not affect travel.
However, if it is related to population screening in high-risk areas, its own health code will turn yellow at this time. At this time, we have to wait for the nucleic acid test results to come out and the health code will turn green before we can travel. Moreover, if it is necessary to issue a 48-hour negative nucleic acid certificate in the arrival area, it will also have a certain impact.
