Displaced Palestinians in Gaza are facing another winter without warm shelters, clothes, or blankets. With little aid getting into Gaza, basic necessities are either absent from market shelves or sold at exorbitant prices. The World Health Organization has warned about the effect cold weather could have on the already dire situation in displaced camps, with the poor water, sanitation, and hygiene situation along with overcrowding in shelters and displacement sites being major drivers of communicable diseases. A drive to vaccinate children against polio in northern Gaza was postponed due to intense bombardment.
