The idea that many COVID cases are asymptomatic has led many of us to hold on to the hope that we have already conquered the novel coronovirus. This is a convenient principle, because if true, you can develop antibodies and assure yourself that the virus is no match for you. Now, a new study is giving even more hope to many Americans. Researchers at UCLA found evidence that the virus could have started in the US as early as late December, based exclusively on the rise of a common COVID symptom at the time: cough. New study, published in Medical Internet Research JournalThe week of 22 December saw a significant increase in health clinic and hospital visits for patients reporting respiratory symptoms and continued until February. Researchers examined data from three hospitals and 180 clinics within the UCLA health system and found that patients who sought medical care because of coughing exceeded the predicted level of 95 percent in those months.
The researchers compared the number of patients reporting cough with the average of five previous sessions. Per 1,000 visits, they found that outpatient offices had two more cough-related seizures than usual. Meanwhile, emergency departments saw 19 more visits than normal and hospitals with acute respiratory failure saw 39 more visits on average. These numbers indicate that there is a statistically significant increase in patients experiencing respiratory symptoms in California from February to December.
