Patients should be referred for COVID-19 testing based on seven symptoms, according to researchers.
According to a study published Tuesday in PLOS Medicine, seven signs can be used to identify COVID-19, especially in locations where testing kits are scarce.
The data showed that people who experienced all seven symptoms – loss or change in sense of smell, loss or change in taste, fever, persistent cough, chills, appetite loss, and muscle aches – tested positive for the virus more than 75% of the time.
According to Imperial College London researchers, using the seven symptoms as the basis for ordering testing would make 30 percent to 40% of symptomatic adults in England eligible for investigation.
According to them, if everyone who was eligible was tested, 70 percent to 75 percent of positive COVID-19 instances would be found.
In an email to Nokia News, research co-author Marc Chadeau-Hyam said, “If we tested everyone reporting at least one of these seven symptoms, we could identify up to 75% of the symptomatic patients, thus enhancing the control of the epidemic’s spread.”
“In areas where testing capacity is limited, focusing on these seven symptoms for triage would enhance the positive detection rate,” said Chadeau-Hyam, an Imperial College professor of computational epidemiology and biostatistics.
According to the Centers for Disease Control and Prevention (CDC), COVID-19 is identified via PCR analysis of saliva samples collected from the nose and throat, which is used to detect genetic material from a specific organism — in this case, the coronavirus.
After the coronavirus was originally discovered in Wuhan in January, China reportedly sent genetic samples to the World Health Organization, and tests were quickly developed and made available.
However, a number of COVID-19 cases in the United States went undiagnosed due to incorrect tests supplied by the CDC in March of last year and a lack of proper testing resources.
According to a study published last month in the journal Nature, up to 60% of cases in the United States have gone unnoticed, resulting in the virus spreading faster.
Chadeau-Hyam and his colleagues collected throat and nose swabs with valid COVID-19 PCR test results from over 1.5 million volunteers aged 5 and up in England for this study.
The information was gathered over the course of eight testing rounds, which took place between June 2020 and January 2021, and participants were asked about symptoms they had in the week leading up to the test.
