Coronavirus Patients Are More Difficult To Detect, Infected But Not Sick
A 20 woman who traveled from Wuhan to Anyang, China, January 10, 2020, then transmitted the coronavirus to five of her relatives even though she had previously been tested negative for the coronavirus.
Case studies published in the Journal of the American Medical Association provide clues about how COVID-19 spreads and is difficult to stop.
"Scientists have asked if you can get this infection and not get sick? The answer is clear, yes," said infectious disease expert at Vanderbilt, University Medical Center, Dr. William Schaffner, as quoted by Okezone, Sunday (2/23/2020).
Schaffner said researchers have reported asymptomatic individuals who can spread the virus. The different thing in this research is offering a kind of natural laboratory experiment.
"You have a patient from Wuhan where the virus originated, traveling to a place where there is no virus. He remains asymptomatic and infects a group of family members, and you have a group of doctors who immediately take advantage of this moment and test everyone," he said.
According to Dr. Meiyun Wang from the Zhengzhou University Community Hospital and her colleague, a 20-year-old woman from Wuhan to Anyang, had a chance to visit several relatives. When they began to get sick, the doctor isolated the woman and tested her for the coronavirus.
Initially, the young woman was negatively affected by the coronavirus. However, he tested positive for the coronavirus in further tests.
All five relatives suffered from COVID-19 pneumonia, but on February 11, the young woman still had no symptoms, her chest CT scan results remained normal.
Also, he did not experience fever, stomach ache, or respiratory symptoms such as cough and sore throat.
The scientists in this study said the prevention of COVID-19 infection proved very difficult. The most important thing right now, according to Schaffner, is finding out how often such transmission occurs.
