Chickenpox surges in Gaza camps as overcrowding and poor sanitation fuel outbreak

Eight-year-old Ruba Saadeh lies in a tent in Gaza, her skin covered in the inflamed red blisters of chickenpox. She shares the space with her entire family. The doctor's instructions were clear: she needs daily cleaning and should be isolated for twenty days. Her nineteen-year-old sister Alaa delivered the diagnosis to a news agency with the weight of an impossible question: "But how can we isolate her? We all live in one tent."

This scene has repeated itself thousands of times across Gaza's displacement camps in recent months. By early July, health officials had documented more than 9,300 suspected cases of chickenpox, the vast majority concentrated in Khan Yunis in the southern part of the territory. The disease has surged as war forced hundreds of thousands of Palestinians into cramped tent settlements where the basic infrastructure of disease prevention simply does not exist. Chickenpox spreads through respiratory infection, which means it moves fastest in exactly the conditions that now define life in these camps: dense clusters of people with no space to separate the sick from the healthy.

Raed Abdel Karim Abu Sariya, a dermatologist working with the Palestinian Red Crescent Society, has watched the outbreak unfold from the front lines of a medical center in Gaza City. He described the mathematics of contagion in the camps with clinical precision: imagine ten, fifteen, or even twenty people living in a single small tent. Where, he asked, would you isolate a patient? Outside his clinic, footage shows stagnant pools of murky water ringed with garbage, children walking barefoot between rows of shelters. Inside, he examined child after child, each one bearing the telltale rash.

For the Saadeh family, the outbreak has exposed the cascading failures of survival under siege. Alaa blamed the spread on the sheer density of the tents and on the water situation: the family receives water once a week, and it arrives salty and unclean. They cannot afford basic cleaning products. Three years of war have left her father unemployed. Ruba, when asked what she had done to deserve such conditions, could only speak to what had been taken from her. She used to shower every day. Now there is no soap, no shampoo, no detergent. She cannot sleep because of the rats.

The chickenpox outbreak is not an isolated crisis but a symptom of a collapsing public health system. Louise Wateridge, a spokesperson for UNICEF, described the broader landscape: respiratory infections, watery diarrhea, skin diseases including fleas, lice, and scabies. More than half of households are reporting skin conditions. An increasing number of children require hospitalization, she said, while Gaza's health care system teeters on the edge of complete failure. The medical infrastructure itself has been severely damaged during two years of war, with Israeli forces targeting facilities they say shelter militants.

What makes the outbreak particularly intractable is that it cannot be solved through treatment alone. Wateridge was direct about this: chickenpox will not disappear unless the root causes are addressed. People need space to live. They need to stop sleeping on floors and among rodents. They need access to medicine and clean water. The disease is spreading not because of any failure of individual families to take precautions, but because precautions have become luxuries that displaced people cannot afford. In wealthier countries, chickenpox is an unpleasant but manageable childhood milestone. In Gaza's camps, it is a window into a humanitarian catastrophe where even the most basic acts of hygiene and isolation have become impossible.
