Disasters and Emergency situations seem to introduce their own set of threats as it relates to sanitation. Many people become ill or even die after exposure to these elements after a disaster usually which results from raw sewerage or chemicals that have contaminated water supplies to cuts and scrapes that may get infected during the recovery period.
Make sure your plan includes sufficient Sanitation and personal Hygiene supplies.

It is very important to follow local official warnings and recommendations, limit your exposure and protect yourself from these environments.
