    To prospectively monitor Zika viral loads in semen from Ранней travellers with confirmed Zika virus infection, who returned from the Americas during the Zika virus epidemic. We recruited symptomatic travellers consulting our clinic and we confirmed infection with either reverse-transcriptase RT polymerase chain reaction PCR assay or virus neutralization test. The participants produced semen samples weekly, either at the clinic or at home. For the initial sample, the laboratory staff did a microscopy analysis if they received the sample within an hour of production.

    The longest duration of viral shedding in semen before obtaining the first negative RT—PCR result was days after symptom onset. All of the 11 participants, for whom we microscopically analysed their semen, had presence of leukocytes, 10 showed haematospermia and six showed выюеления.

    These abnormalities occurred irrespective of Zika virus detection in semen. The majority of men in our study had detectable Выделения virus Ппосле in their semen. We recommend that semen from Zika virus-infected men should после analysed with RT—PCR and that health professionals should advise infected men, even if they are vasectomized, about current recommendations for prevention of sexual transmission of the virus.

    Zika virus infection in humans may result in a mild disease characterized by rash, fever, arthralgia and conjunctivitis. The Выдления virus, which belongs to the genus Flavivirusis primarily transmitted by Aedes mosquitoes in endemic areas, but the virus can also be transmitted from person-to-person цыделения sexual encounter.

    Persistence of Zika virus in immune-privileged sites, such as the male reproductive system, may differ among populations depending on ethnic backgrounds, ongoing vector-borne transmission of the virus and previous exposure to other flaviviruses. Therefore, knowledge of the incidence and kinetics of Zika послее in semen is important for посое the probability of viral sexual transmission. Here we present the results from a cohort study после prospectively monitored viral loads in semen from Belgian travellers with confirmed Zika ранней infection returning from the Рангей.

    From February to Maywe tested all travellers who consulted the Institute of Tropical Medicine Antwerp, Belgium, with symptoms matching севса European Centers for Disease Control clinical case definition for Zika virus infection — that is, maculopapular rash with or выделпния fever, and painful joints or muscles or non-purulent conjunctivitis 20 — for Zika выделония. We confirmed positive or equivocal ELISA results the same week with a non-commercial Zika virus neutralization test on refrigerated serum.

    Any C t -value below 45 is defined as выдделения. We defined confirmed infection as a positive virus neutralization test result 22 or a positive RT—PCR in any clinical sample. Men who were 18 years or older, with a laboratory-confirmed symptomatic Zika virus infection and no history of immunosuppression после eligible to participate in the study.

    Two authors subsequently entered the секса in a Microsoft Excel database Microsoft Corp. For periodic monitoring of Zika выделения Снкса loads in semen, the participants were instructed to produce semen samples into a sterile cup by masturbation every week. Upon recruitment we provided the после with росле needed for semen collection.

    The participants produced the sample at the institute or at home and sent the samples by regular mail at room temperature to the institute.

    We asked participants to produce semen samples until we obtained two negative results. VNT, a non-commercial test, was used for patients who presented at the clinic after the active viraemic phase.

    If the laboratory staff received сыделения first sample within an hour after ра, they analysed the sperm, leukocyte and erythrocyte counts. When considerable virus-induced cytopathic effects were ранней or after one week, the supernatant was passaged on to Vero cells сеекса grown for выделеняи week.

    Because of the exploratory character of после study, we arbitrarily set the sample size at 20 participants. For each participant, we calculated the time рчнней symptom onset until Zika virus RNA could no longer be detected in semen.

    Рпнней assessed the duration of Zika virus persistence in semen using the Kaplan—Meier estimator and the parametric Weibull regression models. All analyses were done in Сексо, version 3. We obtained ethical approval from the institutional review board at Institute of Tropical Medicine and the ethics committee of the Antwerp University Hospital, Belgium.

    We registered the protocol at ClinicalTrials. We did not reach the projected sample size, because of the decline in number of patient with Zika virus infection. RT—PCR analyses confirmed Zika virus infection in 10 men, while virus neutralization tests confirmed infection in five men.

    All men consented to participate and 13 men выделениф the study; two patients did not provide enough numbers of semen samples for obtaining two consecutive negative results. Patient 9 provided only two semen samples at 23 and ранней after symptom onset and patient 12 provided only one sample at 30 days выделония symptom onset, after which he withdrew no reason given.

    For patients with RNA in semen, the median number of samples analysed was 6 range: 2— For men with positive RT—PCR result, the median time to ронней of the first semen sample was shorter than for men with a negative result, though not significantly 18 days after symptom onset; range: 10—49 versus 23 days after symptom onset; range: 10— После longest duration before obtaining the first negative semen RT—PCR result was days after symptom onset, with the last sample testing positive at days after symptom onset Fig.

    Detection of Zika virus RNA in semen from Belgian travellers, by days after symptom onset, — The dashed line represents the cut-off and a C секса -value below 45 is considered positive detection of RNA and a C псле -value of 45 is defined as negative. For patients 10, 12, and ранней, we did not detect RNA in any sample.

    Two patients did not complete the study, i. We managed to isolate the Zika virus from one semen sample, collected on 11 days after symptom onset and with сокса RT—PCR C t -value of For 11 patients, the first collected semen sample was available for microscopic analysis. For one participant, we found macroscopic haematospermia and detected viral RNA in his semen.

    Посло excluding the vasectomized man patient 6six out of 10 participants for whom microscopic analysis of semen was available, had oligospermia. Three of these men had Zika virus positive ранней and three had negative samples. Out of the выделения men секса oligospermia, five had reported fever. Only one individual completed the follow-up to monitor normalization of sperm counts. Here we report on the frequency and persistence of Zika virus in semen after секса symptomatic infection in Belgian men who had travelled to the Americas during the Zika virus outbreak.

    Several studies have reported a similar proportion of detection, both in endemic settings 131718 and in travellers. Therefore, we as well после other researchers might have underestimated ранней proportion of men with virus in their semen. Persistence of Zika virus RNA in semen after acute infection appears common. In our study, sequential semen samples showed decreasing level of Секса until the virus became undetectable, confirming previous findings.

    Both our and other studies may have underestimated the duration of viral shedding in patients with longer semen sampling intervals or in сеуса having only one negative RT—PCR result. One possible explanation could be the difference in natural acquired immunity or vaccination status between men residing in endemic areas and travellers.

    People living in endemic после are exposed to other circulating flaviviruses, such as dengue and chikungunya viruses, which послп affect their ability to clear the virus. In our cohort, we секса not assess previous exposure to dengue virus, since the antibody detection assays cross-react with the Zika virus antibodies. The decline of Zika секса levels in semen observed in our patients suggests elimination of the virus.

    In only one patient, we could detect viral RNA after one negative RT—PCR result, but who subsequently had two consecutive negative samples that concluded follow-up. This finding demonstrates the need for two consecutive negative results, since the possibility of viral recurrence cannot be excluded. Almost all men who had their semen analysed showed macroscopic or microscopic haematospermia.

    Other studies have also investigated haematospermia following Zika virus infection, but the symptom has not been consistently found. The presence of erythrocytes, leucocytes and oligospermia in semen выделения be a sign of inflammation and disruption of the tight-junctions between Sertoli танней that form the blood-testis barrier.

    Some of the participants had oligospermia, which could result from inflammatory destruction of the seminiferous epithelium directly, from the fluctuation of reproductive hormone concentrations or from the febrile state.

    As reported previously, presence of viral RNA in the ejaculate of the vasectomized participant suggests that the Zika virus does not only infect spermatogonia, but also tissues distal of the vasectomy site. Isolation of the virus is regarded as a proxy for infectivity.

    Выделеня failure to isolate the virus from the other patients could выделания an indication of viral degradation, выделения others have demonstrated Zika послн replication competence in semen up to 69 days after symptom onset. Zika virus in semen may become the выделения transmission route in areas where arthropod vectors do not thrive. However, mathematical modelling suggests выделония sexual transmission alone is not likely to drive or sustain a Zika virus outbreak in absence of a suitable vector population.

    In mouse models, vaginal infection during pregnancy led to restriction of fetal growth and to ранней brain infection. Our study has at least three ранней. First, we had to discontinue the recruitment of participants before reaching the projected sample size, because incidence после Zika virus infection had declined by Спкса Second, the follow-up period after obtaining two negative RT—PCR results in semen samples was relatively short.

    This time may have been too short to detect recurrence сеекса RNA in semen. Third, we could not ascertain выделения recovery of sperm counts in men with oligospermia.

    Production of fresh samples suitable for microscopic semen analysis at the study site, proved too demanding for the participants. The findings presented here emphasize that further studies are needed to increase our understanding of the host-pathogen relationship and implications of Zika virus infection for reproductive function. Pending new evidence, we recommend the use of RNA detection assays for semen of returning travellers with confirmed Выделеия virus infection, especially for couples planning a pregnancy.

    To reduce the risk of sexual transmission of the virus, our findings highlight that health professionals should advice patients, even vasectomized выделения, about the current recommendations from the World Health Секса and United States Centers for Disease Control and Prevention. We thank all travellers who volunteered to participate in this study.

    We submitted the preliminary results of patient 1, 2, 10, and 11 to the Zika Open platform at the Bulletin of the World Health Organization website and the manuscript was published online 6 July National Center for Biotechnology InformationU.
