The pace of food and medical aid deliveries picked up in earthquake-shattered Haiti, providing some hope to desperate survivors, but doctors worried disease would be the next big challenge for the tens of thousands left injured and homeless a week ago.
Medical teams pouring in to set up mobile hospitals said they were already overwhelmed by the casualties and warned of the immediate threats of tetanus and gangrene as well as the spread of measles, meningitis and other infections.
No one has begun to estimate the number of injuries from the magnitude 7 earthquake, which destroyed much of the capital Port-au-Prince on Jan. 12. Haitian officials said the death toll was likely to be between 100,000 and 200,000.
One sign of the return to normality was the emergence of street vendors offering fruit and vegetables for sale. Still, on Monday, hundreds of scavengers and looters swarmed over damaged stores in Port-au-Prince, seizing goods and fighting among themselves.
UN Secretary-General Ban Ki-moon said he had recommended to the Security Council that 1,500 police and 2,000 troops be added to the 9,000-member UN peacekeeping mission in Haiti to provide security assistance for Haiti’s shattered government.
More than 11,000 US military personnel are on the ground, on ships offshore or en route, including 2,200 Marines with earth-moving equipment, medical aid and helicopters.
A dozen US military helicopters landed on the grounds of the earthquake-shattered presidential palace yesterday and began dropping off US troops in full combat gear, a photographer said.
The troops unloaded gear in what appeared to be one of the biggest US military deployments so far in the wrecked capital.
Haitian President Rene Preval said US troops would help UN peacekeepers keep order on Haiti’s increasingly lawless streets, where overstretched police and UN peacekeepers have been unable to provide full security.
US Secretary of Defense Robert Gates said US forces would not play a police role but would defend themselves and “have the right to defend innocent Haitians and members of the international community if they see something happen.”
