Hospitals in Haiti say they are overwhelmed by the number of victims that require medical care.
The International Red Cross warns that as many as one third of the country’s 9 million people need emergency aid.
Medical agencies are appealing for doctors and nurses to volunteer to travel to Haiti to help the traumatised.
Many health professionals have also suffered as a result of the quake.
Guy Laroche is a hospital director in Port-au-Prince:
“You know we have nothing, nothing. Our workers have problems at home. So they have to remain at home to resolve their problems. Usually we have 150 doctors at the hospital, now I don’t have 20.”
International aid is now beginning to arrive in Haiti with planes from 30 countries flying in supplies.
However, the airport in Port-au-Prince is full to bursting and there is little or no fuel for the aircraft to return.
