Virus going around

I guess there is a virus going around. My wife's cousin two sons were admitted in Penang two days ago due to vomiting & purging. Last night my four year old nephew & 1 year old niece were also warded in one of the hospital nearby. They have the same symptoms. Well those guys from Penang did visit my nephew's house last week and probably it was spread then from one person to another. Luckily my kids are clear for now. No sign of any symptoms that their cousins are having.

Alhamdulillah.
