The study found other viruses in one in five COVID-positive patients
In the absence of tests for COVID-19, doctors can rely on test results for other viruses. The discovery of another respiratory infection in some cases was considered a sign of the absence of the new coronavirus. New research shows that this expectation can often be wrong.
Perhaps a positive test for a new coronavirus does not mean that this pathogen alone is responsible for the patient's symptoms. On the other hand, the detection of other viruses cannot guarantee that a person does not have COVID-19. This is evidenced by a small study published in JAMA by scientists from Stanford University School of Medicine.
Scientists examined a small group of laboratory-confirmed COVID-19 patients. They tried to find other pathogens that can cause diseases of the respiratory system - bacteria and viruses. Additional respiratory pathogens besides the novel coronavirus were found in 20.7% of study participants.
The authors of the new study examined 1,217 nasopharyngeal swabs from patients with colds, and they found COVID-19 in 9.5% of them. Additional respiratory infections were found in 24 patients with the novel coronavirus. The most frequent satellites of the new coronavirus SARS-CoV-2 were rhinoviruses, respiratory syncytial virus and other coronaviruses (4%).
This suggests that the combination of SARS-CoV-2 with other respiratory pathogens is more common than previously reported, scientists point out. The presence of other viruses can give a false assurance that a patient is COVID-19 free, they emphasize.
Scientists report that their Chinese counterparts have previously claimed that co-infection is rarely found with COVID-19. The American Centers for Disease Control and Prevention recommends, if there is a lack of tests for the SARS-CoV-2 coronavirus, testing for other respiratory pathogens is assumed: their presence is assumed to exclude infection with the new coronavirus.
