Abstract:
The study attempts to determine the prevalence of organisms associated with urethritis in men in rural southwestern Haiti and to determine the association with demographic, clinical and laboratory variables. A standardised verbal interview was conducted; genital examinations were done; urethral swabs were collected for nucleic acid amplification testing, and first void urine was obtained for urinalysis. The mean participant age was 54; 88.8% lived in a rural area. Swabs were positive for Trichomonas vaginalis in 13.7% (28/205), Mycoplasma genitalium in 6.3% (13/205), Chlamydia trachomatis in 4.4% (9/205) and Neisseria gonorrhoeae in 0% (0/205). Subjects who never reported using condoms were nearly 3.5 times more likely to have any positive swab result (OR: 3.46, 95% CI 1.31-9.14). Subjects who reported their partners had other sexual partners or were unsure were more than three times likely to have any positive swab result (OR: 3.44, 95% CI 1.33-8.92). Infections with Trichomonas vaginalis and Mycoplasma genitalium were the most common.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
