The fever did not go away after 3 days and she started throwing up and complaining that her tummy aches once a while. Sensing something not quite right, we brought her back to the paediatrician who then diagnosed that our elder daughter has the rotavirus. A reflection on the events that took place confirmed that this is the most likely cause - she has a bad habit of putting her fingers in her mouth at times and this may have caused the infection.
Rotavirus is a highly infectious disease caused by poor hygiene and attributable to stool contamination. The symptoms include fever, nausea, and vomiting, which are often followed by abdominal cramps and frequent, watery diarrhea. Children who are infected may also have a cough and runny nose. Last night, whilst she was sleeping, she threw up on the bed. Needless to say, her appetite is poor and we had to keep encouraging her to drink more water to keep her hydrated.
She's now with my parents together with the younger one. We don't want them to infect the other kids in child care. The younger one had fever yesterday and we hope she would be able to withstand the infection. They are feeling much better today, thankfully. Hopefully they would be up and about by Monday.
