In order to avoid repetition of the mistakes that have been made in the ascertainment of asymptomatic status in adults who might have COVID-19 infection(1) healthcare practitioners in paediatrics must ascertain the full currently known range of COVID-19 symptoms before a child is declared to be asymptomatic. In the event of an oligosymptomatic or monosymptomatic clinical presentation each of those children with sparse or atypical symptoms should be fully followed up to ascertain if the "stand alone" symptoms are "joined" by new symptoms or whether the oligosymptomatic status persists throughout the course of that child's illness.
Finally, in conformity with the principles of Bayes' Theorem, frontline healthcare workers should be issued with a nomogram spelling out the post test probability of COVID-19 infection(2) in the event of a negative RT-PCR test result. The nomogram should be the subject of regular re-evaluation and updating, on the basis of new information about the authenticity of new symptoms reportedly associated with COVID-19.
