<p>The varying denominators in the result section make it difficult to understand what the authors had in mind. &nbsp;"Most cases 65% (6221/10,138) were aged 25-44 years. Most of the cases were asymptomatic with only 2,204 (12%) having cough, 611(27.7%) fever, 600 (27.2%) shortness of breath, 331(15.0%) sore throat, 249(11.3%) malaise/weakness, 210 (9.5%) runny-nose 197(8.9%) and 9 (0.4%) abdominal pains." The denominator changed from 18338 to 10138 when estimating the proportion for the 25-44 age group. Also, 2204 gave 12% while 611 gave 27.7% obviously from different denominators making it a bit confusing.&nbsp;</p>
