Answered by: Dr Nur Syuhada binti Zulkifli
A friend of mine has been having on and off fever for 4 days, with body aches and headaches. He went to a KK and was tested for dengue and the result came out to be positive. The doctor diagnosed him as having Dengue Fever. However, he has now developed coughs with no phlegm, but no breathing difficulty. If I’m not mistaken, dengue fever doesn’t usually comes with coughing. I’ve read an article regarding Covid-19, saying that observations done in Singapore has shown that there’s a possibility for false-positive results for dengue due to their similarities.
My question is, should my friend go have himself tested for Covid-19? (He has no recent travelling history and no known close contact with positive covid-19 individuals, but I’m concerned due to the increase in sporadic cases). Thank you.
Thank you for your questions.
We understand your worry since we’re now in the midst of coronavirus outbreak.
I am aware of the report done by Singapore about 2 cases that show false positive NS-1 test. But, we can’t conclude just from 2 case. From the situation given above, I’m sure that the medical healthcare would treat him as dengue and monitor his progression first. If they notice that the picture of his symptoms is not a typical dengue, they would probably be more vigilant and do further test as appropriate.
Thus, to answer your question should your friend do COVID-19 test, usually the public hospital would only do it in highr risk patient that fulfill their criteria. To assess your risk, you are encouraged to answer the quiz on Risk Assessment for COVID-19 to evaluate your health status in regards to this disease. After completing this quiz, you will be classified into several categories.
