The World Health Organization (WHO) is "extremely concerned" about a possible outbreak of polio after high concentrations of the highly contagious virus were found in the sewage system in Gaza. WHO warns that infectious diseases can cause more deaths than injuries.
The number of people in Gaza who need to be evacuated for medical care may have risen to over 14,000, according to Ayadil Saparbekov, WHO's head of health crises in the Palestinian territories.
