It is not enough to protect yourself most of the time. Please make sure that the children and all those who handle food are careful about their hygiene. After visiting the toilet, they should invariably wash their hands, clean with soap. Before cooking and eating, hands and plates should be washed clean with treated water. Children and those who handle food should not have long finger nails.
Dust accumulates in finger nails and carries the infection.
While handling water glasses, fingers should never be dipped into them. Food should never be served with hands. It is safe to boil all food and milk before consuming it. These infections are a result of eating or drinking contaminated or untreated food, milk, water etc. Infections can also spread by unhealthy habits like sucking thumbs, putting toys in the mouth etc.
