Eating oranges does not usually make a person positive for the new coronavirus. Whether or not an orange is positive for Nucleic Acid is not related to the orange itself. If an orange carries the Neocollins virus, eating the orange may cause a person to be positive for Nucleic Acid, but the chances of this are relatively low. New coronavirus is generally transmitted through respiratory droplets, direct contact, aerosol contact, etc. Therefore, if the air and objects that human beings come into contact with carry the new coronavirus, they may infect human beings through these routes, while the new coronavirus nucleic acid is detected by testing the specimen of human nasopharyngeal swab to see if it contains the nucleic acid of the new coronavirus, and if it has been infected with the new coronavirus, then it will be positive. If the orange itself does not have the neocoronavirus, it is unlikely that eating the orange will cause a positive neocoronavirus nucleic acid result, nor will other foods cause a positive nucleic acid result if they do not carry the virus. When a new crown nucleic acid result is positive, it needs to be reported immediately according to local policy, and actively cooperated with quarantine and treatment.
