In Cuba, these checks have been used in a couple of studies to estimate frequency of chlamydia infections, either by use of polymerase chain reaction or actual-time PCR. Despite these findings and the identified relationship between HPV and cervical cancer, at the time of this writing, no national baseline studies have been conducted on HPV prevalence and circulating genotypes in Cuba’s feminine population. Since 1968, Cuba has carried out a cervical most cancers early prognosis program, now carried out via the nationwide network of neighborhood household doctor-and-nurse offices.

It helps the necessity to include HPV vaccination within the National Immunization Program and contributes information about HPV genotypes in Cuba probably helpful for considering vaccine candidates for home production. Human papillomavirus and Chlamydia trachomatis are among the many most frequent causes of sexually transmitted infections on the earth. WHO estimates that close to 290 million women have HPV, and approximately 131 million chlamydia circumstances are reported yearly. Despite advances in STI analysis, therapy and prevention, these two infections still represent a worldwide well being downside.

These genotypes have been detected in equal proportion in Havana residents . Of the 500 women examined, 14.8% (seventy four/500) have been contaminated by one or more HPV genotypes. A complete of 29 genotypes had been identified, of which seventy nine.7% (59/seventy four) have been excessive-danger HPV. Genotype 16 was the most frequent, followed by 31, and then 33, 53, sixty one and sixty six, in equal proportions .

Figure 2B exhibits frequency of diagnosis for the totally different genotypes in this province. Prevalence of HPV 31 and 33 were higher in women in Villa Clara compared with the opposite provinces studied. Figure 2 exhibits frequencies of various genotypes by province. In Havana residents, 14 genotypes were recognized and, of them, 10 (71.4%) had been excessive-risk HPV.

For the previous a number of years, the Cuban public health system has been using rapid chlamydia tests for analysis. However, as a result of their lack of specificity, false positives happen from cross-reactions with antigens from other micro-organisms, and frequencies of up to 80% have been reported in women with decrease abdominal pain. Nucleic acid amplification testing has larger sensitivity and specificity for chlamydia analysis, but the price is prohibitive for broad use in medical analysis in low- and center-earnings international locations.

The program screens sexually active women aged 25 to fifty nine years, for whom protocols point out a Pap check every 3 years. The program may have contributed to the decline in cervical cancer cuban woman mortality rates from above 20 per one hundred,000 women in 1965 to 7.7 per a hundred,000 in 2010. In 2016, it reached 9.1 per one hundred,000 and in 2018, 9.7 per a hundred,000.

Frequencies of the completely different genotypes in this province are proven in Figure 2C. Genotype sixteen was much less frequent in women in Holguín than those in Havana and Villa Clara. In Villa Clara Province, 20 HPV genotypes have been recognized, of which 12 (60%) have been high-threat HPV.

Although these rates are among the many lowest in Latin America, the will increase are trigger for concern. IMPORTANCE This paper characterizes frequency of HPV and Chlamydia trachomatis infection in women of three Cuban provinces and highlights the need to examine chlamydia infection in younger and adolescent women.

Human papillomavirus an infection from genotypes sixteen, 31, 33, 53, sixty one, sixty six, sixty eight and 89 was related to the 7.9% (30/382) of girls who had constructive Pap checks. Infection from Chlamydia trachomatis was constructive in 1% (5/500) of girls, all aged ≤۲۵ years. Coinfection by Chlamydia trachomatis and HPV was present in one woman contaminated with human papillomavirus genotype 61.

Human papillomavirus was detected in 14.8% (seventy four/500) of the ladies. Of the 29 genotypes recognized, 79.7% (59/74) had been oncogenic high-threat varieties. Type sixteen was probably the most regularly identified (23%; 17/74), followed by kind 31 (10.eight%; eight/74) after which by sorts 33, 53, sixty one and 66 in equal proportions (eight.1%; 6/74). Infection frequency was larger in women aged ≤۲۵ years (38.8%; 31/eighty), college students (forty six.7% 7/15), single women (23.zero%; 40/174) and among those who reported having greater than three sexual partners within the last 2 years (41.5%; 17/forty one). Differences have been discovered among provinces for circulating genotypes and an infection-related variables.

Greater frequencies are concentrated in students, single women, people who smoke and in oral contraceptive customers. The percentages of those who tested optimistic elevated because the variety of sexual partners within the last two years elevated and the sooner women started having sexual relations. Although women with a history of STIs had the best frequency, there have been solely small variations between them and people with no STI historical past. We additionally found only a small difference associated to IUD use, however women who reported regular condom use had barely greater frequencies than women who didn’t . In Holguín Province, 19 viral genotypes have been detected, of which 11 (57.9%) were high-threat HPV.

The proportion of girls contaminated by HPV 16 was greater in Havana . For high-danger HPV 35 and sixty eight, differences were also found between Havana and the other provinces.
