In paediatric patients, vomiting, headache, myalgia, and a
flushed appearance were the common clinical manifestations in
the current study; these have been noted with high frequencies in a
different study20 (Table 2). In another study, headache and
myalgia/arthralgia were not noted in children;16 this might be
due to difficulties in expressing certain complaints by children in
certain populations. In the present study cohort, pleural effusions
and ascites were not common in children, but high frequencies of
pleural effusions and ascites have been noted in a previous study.20.
