There is no evidence to suggest that you cannot eat oranges for the new coronavirus nucleic acid test. The substance tested for nucleic acid is the genetic material of the virus, and oranges will not affect the nucleic acid results. The new coronavirus is a respiratory virus, after infection, it will exist in the human respiratory system, therefore, at present, the main way to determine whether the human body is infected with the virus is through the oropharyngeal swabs, nasopharyngeal swabs whether there is new coronavirus nucleic acid, and at present, a positive nucleic acid test is one of the ways to diagnose the infection of the new coronavirus. Oranges belong to a kind of fruit, will not affect the human body itself oropharyngeal swabs, nasopharyngeal swabs in the presence of viral nucleic acid, so do nucleic acid can eat oranges. Not only oranges, but any food will not affect the nucleic acid test, and when the nucleic acid results are abnormal, they should be reported and actively self-isolated.
