As is known to all ,during the past years many countries and areas in the world were hit by some deadly diseases .To protect us from them ,I think the most important thing is to put the prevention first .In our daily life ,we should develop good habits to keep us healthy.If you want to ,please take my following advice.

It's important for us to be careful about diseases all the time .Once you pick up a disease ,see a doctor as soon as possible and make sure you don't carry the virus of disease everywhere

When you are thirsty , never drink water that is not boiled, for it is easy to cause a disease from water that is not clean. Being out , never eat food that has been kept outside for a long time . You should also make sure that the bowls , spoons and other dinner set have been washed in a proper way.
