MANILA, Philippines?Lying on a bamboo bed with the sickening smell of rotten garbage wafting through a tiny window at an evacuation camp, a weary Marites Gural gave birth to her sixth child on Thursday.

After nearly six hours of labor, Gural delivered a 2.9-kilogram (6.5-pound) boy her husband named King Louie, to give the boy from a sprawling Manila slum an air of royalty.

"Thank you, thank you for helping me," Gural whispered to Jean Demegillo, a midwife who has volunteered to help pregnant women since the September 26 floods devastated parts of Metro Manila, killing 298 people.

"My baby and I wouldn't have made it without your help."

Gural, 34, gave birth to King Louie in a concrete building that had been converted into a makeshift emergency ward beside a covered basketball court housing nearly 800 homeless flood victims.

She was among the more than 14,000 pregnant women scattered in hundreds of cramped evacuation camps in Manila and surrounding districts, according to estimates from the United Nations Population Fund (UNFPA).

With more than 300,000 people in the evacuation centers desperately needing basic supplies such as food and water, pregnant women have been largely overlooked, said the UNFPA's Philippines representative, Suneeta Mukherjee.

Without adequate health care, they and their babies could die, Mukherjee warned.

"The problem with pregnant women is that they have to deliver. They can't stop it when their time comes," Mukherjee told Agence France-Presse.

"But... (if) they don't have facilities, the whole thing can get septic.

"There are a lot of pregnant and postpartum women in the evacuation centers who do not have access to prenatal, natal and post-natal care, and we cannot allow the situation to remain this way."

Of the 18 government-run pediatric and health care centers in the suburban area of Cainta where Gural gave birth only three are still operational, with all the others still under water, Mukherjee said.

Cainta's municipal health chief, Olga Abellanosa, said there were 2,158 pregnant women monitored in evacuation camps in the area.

"They can't go back to their ruined communities, and we don't have the capacity to take them all in," Abellanosa said.

"Many of them have been neglected, with some told to remain in their partly submerged homes while the husbands sought help."

Gural's contractions began at dawn and steadily intensified over several hours.

With no doctors around and no transport to rush her to hospital, her husband called in the neighborhood?s traditional healer, an elderly woman with a weather-beaten face whose best advice was to wait it out.

Without professional help in the form of a midwife, Gural would have died from internal bleeding, according to Demegillo.

King Louis was the second baby born in less than 12 hours at a Cainta evacuation site.

Earlier in the week, a 30-year-old woman gave birth to her second child by herself, with a pair of unsterilized scissors used to cut the umbilical cord, according to the municipal health office.

As Gural was giving birth, Mukherjee's team was giving about 500 pregnant evacuees pre-natal check ups and hygiene kits across town at the municipal centre.

"I had intended to go there, but my boy decided to be born today," Gural said.
