These Morning-After Pills May Prevent
Sexually transmitted infections have soared in recent years in the United States, prompting an urgent search for solutions. New research suggests that a widely available antibiotic, taken after sex, may help stem the tide.To get more news about vigrx plus where to buy, you can visit vigrxplus-original.com official website.
A single dose of doxycycline taken within 72 hours of unprotected sex dramatically cuts the risk of a bacterial S.T.I., studies have found. The approach seems most effective for preventing chlamydia and syphilis, and slightly less so for preventing gonorrhea.
The strategy has been shown to work among trans women and men who have sex with men who are at high risk for acquiring an S.T.I. But the pills have not shown a benefit in cisgender women (whose gender identity matches the sex assigned at birth).
With the resurgence of S.T.I.s, researchers and health officials are eager to find new prevention strategies. Researchers have also found that a meningitis vaccine halved the incidence of gonorrhea. The two diseases are caused by closely related bacteria.
The most recent data were presented last month in Seattle at the Conference on Retroviruses and Opportunistic Infections.
“While condoms work really well when people use them, they’re not always accessible to people in their relationships,” said Dr. Jenell Stewart, an infectious diseases physician at Hennepin Healthcare and the University of Minnesota. “We need to have solutions beyond that.”
The Centers for Disease Control and Prevention does not yet recommend post-exposure doxycycline to prevent S.T.I.s. But based on the strength of the new evidence, some cities like San Francisco are already offering the antibiotic to those at high risk of infection with chlamydia, syphilis and gonorrhea. Health officials are calling it “doxy-PEP.”
“For those who have a lot of S.T.I.s, I think this is certainly something I hope that the C.D.C. can provide some guidance,” said Dr. Annie Luetkemeyer, an infectious disease physician at Zuckerberg San Francisco General Hospital and Trauma Center.
Syphilis was nearly eliminated in the United States in 2000; rates of gonorrhea, too, were declining around that time. But the infections have resurged, in large part because of the shuttering of sexual health clinics across the country.
Between 2017 and 2021, syphilis cases shot up by 68 percent and gonorrhea cases by 25 percent. About half of those new infections were in teens and young adults.
The incidence of S.T.I.s also rose in women, and Black women in particular. Rates of congenital syphilis, acquired during gestation from an infected mother, increased by nearly 200 percent during the period.
On any given day in 2018, about one in five Americans had an S.T.I., the C.D.C. has estimated. Although many infections are easily treated with antibiotics, many people remain undiagnosed because they may not have symptoms or have poor access to health care.
Left untreated, syphilis can damage the reproductive system, brain, heart and other organs. Congenital syphilis can even lead to death; nearly 7 percent of infants with syphilis in 2020 did not survive.
The new studies looked primarily at the use of doxycycline in men who have sex with men, who account for more than 40 percent of S.T.I.s in the United States. Generally, the participants were given a supply of the antibiotic and told to take two pills within three days of a potential exposure to an S.T.I.
