The World Health Organization says 22 people injured in the earthquake in Pakistan have died of tetanus infections in the past few days.
A spokeswoman for the organization said Thursday the situation appears to be stabilizing. There have been 111 tetanus cases reported since the quake struck on October 8, but just seven new cases in the past two days.
U.N. officials are warning that more quake survivors could perish in coming months unless they get food and shelter before winter.
On Wednesday, a U.N. official said international donors pledged an additional $580 million for earthquake relief efforts.
The death toll in Pakistan now stands at more than 54,000 people, and officials say rebuilding damaged areas will cost $5 billion.
