 Nearly four months of high-intensity conflict in the Gaza Strip has caused catastrophic humanitarian consequences with severe public health implications. The immense stress that civilians have had to endure, coupled with a lack of access to potable water, sanitation, electricity and public health care, has had a significant toll on the population. Mass displacement with hundreds of thousands of people living in tent cities, with no toilets, a lack of access to water and food and wet winter conditions have created a dire situation. Already cases of diarrhea, upper respiratory infections, scabies and chickenpox have become commonplace. If more is not done, the conditions risk the spread of disease such as cholera, meningitis and hepatitis A.
