You will not test positive for novel coronavirus by drinking Coke. A positive test for novel coronavirus means that after collecting specimens from the respiratory tract, blood or feces of the population, the specific nucleic acid sequence or protein structure of the novel coronavirus can be found in the specimens through a series of extraction, experimentation or a simple reagent kit, and the result means that they may be infected with the novel coronavirus, and need to be re-verified. Cola, which is commonly used in daily life, does not contain novel coronavirus. Since drinking cola will not induce infection in human beings, novel coronavirus will not be found in specimens of human respiratory tract, blood, feces, etc., and the results of the test are unlikely to be positive. If the novel coronavirus remains on the cola bottle, it may lead to novel coronavirus infection and there is a possibility of testing positive for novel coronavirus. The probability of a positive nucleic acid test increases when one has traveled to a high-risk area in an outbreak, had contact with a patient or asymptomatic infected person, or traveled to or from a high-risk area without proper protection.
