#coronavirus #Thailand #dengue #Singapore A case study report out of Singapore shows that COVID-19 patients can come back false positive for the dengue virus, complicating diagnosis and casting substantial doubt on the ability of Thailand to identify COVID-19 cases with their limited testing approach . SARS-CoV-2 appears to be able to cause false positives for dengue virus in rapid serological testing, which is the most common way to screen for dengue. Secondly, having narrow criteria for testing for COVID-19 is preventing many people from being tested. This is absolutely the case in Thailand, as patients must have a fever and cough and also have a travel history to a very limited number of countries. This list of countries is often way behind where infections are currently widespread. Many, many people have missed diagnoses, meaning many people are never tested. And, again, there is uncertainty in detecting the novel coronavirus. As I’ve pointed out in several of our videos, even if you’re tested, the results are not always reliable. Because of the newness, we just don’t have strong lab methods. Our sensitivity can be as low as 60%, which means we have many false negatives.
