A British team reporting in the Lancet-Respiratory Medicine that they have developed a new test that can quickly diagnose respiratory virus infections, improve treatment efficiency and reduce the risk of antibiotic use.
The new method, developed by a team led by academics at the University of Southampton in the UK, uses cotton swab to take samples of a patient's secretions and then process them in a portable testing instrument, combined with a quick molecular test to obtain a diagnosis within an hour, while traditional methods require analysis in the laboratory for several days.
common respiratory viruses: rhinoviruses, influenza viruses, coronaviruses, adenoviruses, respiratory syncytial viruses, side-flu viruses, Eko viruses and Kosage viruses.
team recruited 720 patients with acute respiratory diseases for comparative testing in the winters of 2015 and 2016, half of whom were diagnosed using new methods.
showed that the group of patients who used the new method were treated correctly more quickly. Tristan Clarke, a scholar at the University of Southampton and one of the authors of the
report, said health care providers used the method to find out in a short period of time what viral infection a patient was infected with in order to isolate and take medication in a timely manner, helping to reduce the chances of infection and speeding up patient recovery.
The new approach also helps address antibiotic resistance, he said, because when patients are quickly diagnosed with a virus that is resistant to antibiotics, health care providers can target antibiotics in their treatment.
