Is a positive pharyngeal swab indicative of novel coronavirus?

The novel coronavirus is a relatively common viral infection, primarily detected through nucleic acid testing for COVID-19. Does a positive throat swab mean infection with the novel coronavirus?

Does a positive throat swab indicate novel coronavirus infection?

A positive result in the throat swab nucleic acid test confirms infection with the novel coronavirus. Once diagnosed, individuals should immediately begin home isolation and take personal protective measures. Under a doctor's guidance, medications such as acetaminophen tablets or ibuprofen tablets may be taken for treatment. If there is no fever and the nucleic acid test result is negative, infection can be ruled out. Currently, nucleic acid testing is the primary method for diagnosing COVID-19. It is convenient and typically involves collecting samples from the throat or nasal area. This method is well-tolerated by patients and widely applicable, suitable for both elderly individuals and children to test for secretions and screen for infection.

If clinical symptoms are evident but the initial test result is negative, infection cannot be completely excluded. Diagnosis requires comprehensive evaluation based on other test results and repeated nucleic acid tests. With appropriate symptomatic treatment and enhanced individual immunity, test results may eventually turn negative. Therefore, preventive measures should be strengthened, including ensuring adequate sleep and preventing opportunistic viral infections. When going out, protective measures such as wearing masks should be observed, and crowded places should be avoided.

In daily life, physical immunity can be enhanced through regular exercise and balanced nutrition. Diet should mainly consist of light foods, with increased intake of vitamin-rich or collagen protein-rich foods. We hope this response has been helpful to you. Wishing you good health and happiness!
