India, April 4 -- The United Nations on Friday said 280,000 Gazas are estimated to have been newly displaced since the intensification of hostilities began in the region on March 18.

"Increasing numbers of people are moving into the remaining shelters which are already overcrowded. Infestations of fleas and mites are reported, causing skin rashes and other health issues, " The UN Office for the Coordination of Humanitarian Affairs (OCHA) said in a statement.

OCHA says that addressing these challenges remains difficult due to the lack of necessary materials available in Gaza to implement vector control measures or improve hygiene conditions.
