Study: Women unaware of sexual disease risks ■ Millions are uninformed about the practices of their partners, die Alan Guttmacher Institute says. WASHINGTON (AP) - An esti mated 17 million American women are at ride of a sexually transmitted disease because either they or their partners recently have had sex with someone else, a study by the Alan Guttmacher Institute says. Some 3.5 million women are not aware of the risk because they believe they are in a mutually monogamous relationship, the study said. But contrary to popular percep tions, the proportion of sexually active Americans who have had only one sex partner in a given year- at least three quarters - has not changed significantly in a decade, the study said. The more sexual partners a person has, the more likbly he or she is to encounter someone infected with the AIDS virus or other sexually transmit ted diseases. Even someone who has had only one sexual partner can be placed at risk if that partner has ever had sex with someone else - one reason health experts recommend using con doms. Guttmacher researcher Lawrence Finer combed three federal behavior surveys to estimate how many women are at risk. Some 5.4 million women ages 15 44 report having had more than one sex partner in the previous year, concluded a 1995 national study. About 15 percent of women in that study also reported that a husband or boyfriend had had another sexual part ner during that time. But another study found 23 percent of men reported more than one sexual partner in a year. Finer combined the data to con clude that some women were being cheated on, and found about a third of sexually active women are at risk of dis ease because of either their own or their partners’ sexual history. The study is clearly an estimate, but appears sound based on the best avail able data, said William Mosher of the Centers for Disease Control and Prevention. The Guttmacher Institute is a pri vate research group that focuses on reproductive health issues. 66 die in Mexico VILLAHERMOSA, Mexico (AP) - Thousands of people huddled on their rooftops Wednesday to escape flooding in the Gulf coast state of Tabasco as a tropical depres sion dumped torrential rains on cen tral and southern Mexico. At least 66 people have died because of flooding in 10 states. Local media said the death toll could rise as more victims are recovered from mudslides and reports come in from isolated communities. Torrential rains from the season’s 11th tropical depression have caused southeastern Mexico’s worst flood ing in 40 years and have forced more than 157,000 people from their homes over the past week. “Not even the army’s efforts have been enough. Unfortunately it is now impossible to control the flow of water,” said Georgina Trujillo, municipal president for Tabasco’s capital, Villahermosa, 410 miles east of Mexico City. The ports of Tampico, Altamira and Tuxpan in the Gulf of Mexico have been closed to all shipping indefinitely, the, federal Communications and Transportation Secretariat said.

Thousands of people trying to flee were stranded at bus stations. “We had never seen anything like this,” truck driver Armando Rosas said Wednesday after waiting for more than 12 hours to cross a flooded highway in the central state of Hidalgo n‘They say it could take two more days before we can get across.” ; In other states, those who could not flee clung to trees or rooftops awaiting help. Rescue workers rowed boats down the streets of Tulancingo, 60 miles northeast of Mexico City. Military troops and civil protec tion workers were called to help with emergency efforts throughout the region. Tropical Depression No. 11, cen tered about 150 miles north-north east of Veracruz, weakened Wednesday afternoon, according to the U.S. National Hurricane Center. But forecasters said heavy rains were likely to continue over eastern Mexico. In the east-central state of Puebla, whose inland mountains are raked by rain and winds from the Gulf of Mexico, state officials said Wednesday at least 41 people had been killed in mudslides or flooding, and some 19,000 people evacuated to 56 shelters. In the coastal state of Veracruz, state officials said 19 people had died, including three killed when their rescue helicopter crashed Tuesday in Hueyapan de Ocampo, 50 miles east of the coastal city of Coatzacoalcos. Some 30,000 were evacuated. In the neighboring state of Tabasco, already drenched by a week of rain, officials said four people died and 58,000 people were forced from their homes. ^ I Thatcher makes plea for Pinochet BLACKPOOL, England (AP) - Former Prime Minister Margaret Thatcher, in an impassioned plea for the release of Gen. Augusto Pinochet, declared Wednesday that the former Chilean dictator is on trial “for defeat ing communism.” , , .. ir M “Make no mistake, revenge by the left, not justice for the victim, is what the Pinochet case is all about,” she told a rally held with the Conservative Party’s annual conference.
