Catching flu is very easy, you go to wet market, public crowded place or in malls you would surely get a great chance of having flu or viruses from other people. Especially during holidays so when you have the access to shop online, why not do it? It is convenient and it is just a click away, you will just wait at home and your order will be in your doorsteps. But if you are like me, who is not so fond of shopping online, if you are like me who always rush to the malls, then you should not forget to wash your hands to avoid contamination, you should also avoid placing your hand in your mouth area. Most viruses can spread through contact, so washing your hand is a must especially when you are coming from public places.
