SANE Knowledge of HIV nPEP: Identifying Deficits.

BACKGROUND: Discussing the risk of exposure to human immunodeficiency virus (HIV) and assessing the need for HIV nonoccupational postexposure prophylaxis (nPEP) are essential components of providing care to victims of sexual assault. Current literature on the topic of HIV nPEP for victims of sexual assault surrounds risk of exposure, patient adherence, access and barriers, current practices, and standardized order sets. A significant gap in the literature concerning sexual assault nurse examiner (SANE) knowledge of HIV infection and HIV nPEP evidence-based practice guidelines was identified. The purpose of this research was to assess SANE knowledge surrounding HIV infection and evidence-based practice recommendations for HIV nPEP use in victims of sexual assault. METHODS: A 20-item knowledge survey was created using QuestionPro. The aim of the survey was to measure SANE knowledge of HIV transmission, pathophysiology, nPEP medications, and evidence-based practice guidelines for victims of sexual assault. In addition to the 20 knowledge items, 15 demographic questions were included. The study design was cross-sectional, descriptive, and comparative. A total of 411 participants completed the survey. RESULTS: Data analysis revealed knowledge deficits for topics such as risk of HIV transmission, nPEP indications, laboratory testing, drug regimens, nPEP timing, mechanism of action, medication contraindications, and adherence issues. The overall mean score for the knowledge survey among all participants was 13.36 out of 20 (66.8%). CONCLUSION: A knowledge deficit among SANEs surrounding HIV infection and HIV nPEP evidence-based practice guidelines for patients who experienced sexual assault was identified. The study highlights the need for additional education for specialized nurses who are providing care to victims of sexual assault.

A prospective study on health seeking behaviour and post exposure prophylaxis received by animal bite victims at the anti-rabies clinic in a tertiary care centre of urban Bangalore.

Background: Rabies is 100% preventable by administering early and complete post exposure prophylaxis (PEP). Animal bite victims must have the knowledge and attitude necessary to seek appropriate medical care at the earliest to receive the required PEP. Objectives: The present study sought to ascertain the health-seeking behavior of animal bite victims, their knowledge and attitude regarding rabies prophylaxis, the PEP they received, and their level of compliance with the full course of anti-rabies vaccination. Methods: The study included animal bite cases that presented to the anti-rabies clinic and matched the eligibility criteria. All the required details were recorded using an internally validated structured questionnaire. All participants were followed up for six months to ensure their health conditions and compliance with the vaccination schedule. Results: Out of 1058 respondents, 57.9% were adults, with 46.6% belonging to middle socioeconomic class. 91.1% of them were informed biting animals as dogs. Before arriving at the anti-rabies clinic, 93.3% of the study subjects washed their wounds, and 62.4% visited to another health facility. Rabies knowledge was inadequate among the study participants, only 54.8% being mindful about the disease and its prevention. The compliance with the full course of antirabies vaccination was found to be 77.9%. All subjects were healthy, confirming that PEP is safe and effective. Conclusion: Regular social and behavioral change communication (SBCC) needs to be implemented with regard to health-seeking behavior.

Live Vaccine and Varicella Postexposure Prophylaxis in Pediatric Liver Transplant Recipients: A Survey of Practice in Australia and New Zealand.

BACKGROUND: Administration of live vaccines following liver transplant (LT) has historically not been recommended due to concerns regarding risk of vaccine-attenuated disease. However, there is evidence suggesting that in select transplant recipients live vaccinations can be administered safely. Studies in other regions have indicated that despite this evidence many clinicians remain hesitant to administer live vaccinations. METHOD: A REDCap survey was distributed to gastroenterologists, pediatricians, and infectious diseases physicians at pediatric centers across Australia and New Zealand via email between September and November 2023. The survey included a series of questions regarding live vaccine and varicella postexposure prophylaxis (PEP) practices in pediatric LT recipients and barriers to live vaccine administration in this cohort. RESULTS: There was a total of 16 responses to the survey, from 10 different pediatric centers, including 10/11 pediatric gastroenterology centers and all four pediatric LT centers in the region. Only 31% (5/16) of respondents (from 3/10 different centers) offer live vaccines. The main barrier to live vaccine administration was clinician reluctance and the main reason for not offering live vaccines was insufficient safety data. Sixty-nine percent (11/16) of respondents take vaccination status and/or serology into account when deciding whether to offer varicella PEP to this cohort. Respondents universally offer varicella zoster immunoglobulin as PEP, though 31% (5/16) also offer antiviral medication. CONCLUSIONS: Many clinicians in our region remain hesitant to provide live vaccines to pediatric LT recipients, with concerns regarding insufficient safety data. Updated local guidelines may help to address this.

Prescription of HIV Post-Exposure Prophylaxis in emergency care units and return for follow-up appointments in specialized services in Salvador, Brazil, 2018: a cross-sectional study.

OBJECTIVE: To analyze HIV Post-Exposure Prophylaxis (PEP) prescription and return for follow-up appointments. METHODS: This was a descriptive cross-sectional study using data on people who sought PEP in emergency care units (UPAs) and specialized medical services in Salvador, BA, Brazil, between January-December/2018. RESULTS: Of the 1,525 people who sought PEP at UPAs, 1,273 (83.5%) met PEP eligibility criteria, while 252 (16.5%) did not; of the eligible group, 1,166 (91.6%) had antiretrovirals prescribed, while 107 (8.4%) eligible people did not; of the total number of people with PEP prescriptions, only 226 (19.4%) returned for the first follow-up appointment, 115 (9.9%) for the second, and 33 (2.8%) for the third in order to complete the protocol. CONCLUSION: We found a significant proportion of eligible users who did not have PEP prescribed at UPAs and a significant loss of return for specialized service follow-up appointments.

Immunogenicity of 4-dose Essen intramuscular regimen for rabies post-exposure prophylaxis: A multi-center cross-sectional study in China.

BACKGROUND: The 4-dose Essen intramuscular (IM) regimen for rabies post-exposure prophylaxis (PEP) has been recommended by Advisory Committee on Immunization Practices (ACIP) and World Health Organization (WHO), but the large-sample clinical evidence is still limited. METHOD: Rabies virus neutralizing antibodies of 11,752 patients were detected from 409 rabies prevention clinics in 27 provinces in China. Patients with serum collected before or no later than 1 h after injection on the day of the fifth dose (day 28) of 5-dose Essen regimen were included in Group A to observe the immune efficacy of 4-dose Essen IM regimen, and patients with serum collected 14-28 days after injection of the fifth dose were included in Group B to observe the immune efficacy of 5-dose Essen IM regimen. RESULTS: Finally, 2351 cases met the inclusion and exclusion criteria, including 2244 cases in Group A and 107 cases in Group B. The antibody titer of Group A was higher than that of Group B [12.21 (4.15, 32.10) IU/ml vs. 9.41 (3.87, 27.38) IU/ml] (P = 0.002). In Group A, the median antibody titers were 4.01IU/ml, 11.63IU/ml and 29.46IU/ml in patients vaccinated with purified hamster kidney cell vaccine (PHKCV), purified Vero cell vaccine (PVRV), and human diploid cell rabies vaccine (HDCV), respectively, with statistical significance (P < 0.001). CONCLUSIONS: The 4-dose Essen IM regimen could provide satisfactory immune effect, and HDCV induced higher antibody titer than PHKCV or PVRV.

Rabies knowledge gaps and risk behaviour in Dutch travellers: An observational cohort study.

BACKGROUND: Travellers visiting rabies-endemic countries are at risk of rabies infection. Assessing travellers' knowledge and risk perception of rabies and risk behaviour during travel can help identify knowledge gaps and improve pre-travel risk education. METHODS: Cohort study in Dutch adult travellers, using two surveys: one before travel to assess knowledge and perception of rabies, and one after return to identify risk behaviour during travel. RESULTS: The pre-travel and post-travel survey were completed by 301 and 276 participants, respectively. 222 participants had travelled to a high-risk rabies-endemic country. 21.6 % of the participants scored their rabies knowledge as poor. Some participants were unaware cats or bats can transmit rabies (26.6 % and 13.6 %, respectively), or that post-exposure prophylaxis (PEP) is required for certain exposures such as skin abrasions without bleeding or licks on damaged skin (35.5 % and 18.9 %, respectively), while 27.9 % of participants did not know PEP needs to be administered within one day. 115 participants (51.8 %) reported any form of contact with any animal during travel. Two participants reported animal exposure, of which one took adequate PEP measures. Risk factors for animal contact abroad were regularly touching cats or dogs at home or abroad, longer travel duration, having pets during childhood and being an animal lover. CONCLUSIONS: Pre-travel rabies risk education currently does not meet travellers' needs, which is reflected in knowledge gaps and engagement in risk behaviour during travel. During pre-travel health advice, avoiding animal contact abroad should be emphasized, and additional education is required about indications for PEP.

Development of mRNA rabies vaccines.

Rabies, primarily transmitted to humans by dogs (accounting for 99% of cases). Once rabies occurs, its mortality rate is approximately 100%. Post-exposure prophylaxis (PEP) is critical for preventing the onset of rabies after exposure to rabid animals, and vaccination is a pivotal element of PEP. However, high costs and complex immunization protocols have led to poor adherence to rabies vaccinations. Consequently, there is an urgent need to develop new rabies vaccines that are safe, highly immunogenic, and cost-effective to improve compliance and effectively prevent rabies. In recent years, mRNA vaccines have made significant progress in the structural modification and optimization of delivery systems. Various mRNA vaccines are currently undergoing clinical trials, positioning them as viable alternatives to the traditional rabies vaccines. In this article, we discuss a novel mRNA rabies vaccine currently undergoing clinical and preclinical testing, and evaluate its potential to replace existing vaccines.

Oral Nirmatrelvir-Ritonavir as Postexposure Prophylaxis for Covid-19.

BACKGROUND: Clinical trials of treatments for coronavirus disease 2019 (Covid-19) have not shown a significant benefit of postexposure prophylaxis. METHODS: We conducted a phase 2-3 double-blind trial to assess the efficacy and safety of nirmatrelvir-ritonavir in asymptomatic, rapid antigen test-negative adults who had been exposed to a household contact with Covid-19 within 96 hours before randomization. The participants were randomly assigned in a 1:1:1 ratio to receive nirmatrelvir-ritonavir (300 mg of nirmatrelvir and 100 mg of ritonavir) every 12 hours for 5 days or for 10 days or matching placebo for 5 or 10 days. The primary end point was the development of symptomatic SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection, confirmed on reverse-transcriptase-polymerase-chain-reaction (RT-PCR) or rapid antigen testing, through 14 days in participants who had a negative RT-PCR test at baseline. RESULTS: A total of 2736 participants were randomly assigned to a trial group - 921 to the 5-day nirmatrelvir-ritonavir group, 917 to the 10-day nirmatrelvir-ritonavir group, and 898 to the placebo group. Symptomatic, confirmed SARS-CoV-2 infection developed by day 14 in 2.6% of the participants in the 5-day nirmatrelvir-ritonavir group, 2.4% of those in the 10-day nirmatrelvir-ritonavir group, and 3.9% of those in the placebo group. In each nirmatrelvir-ritonavir group, the percentage of participants in whom symptomatic, confirmed SARS-CoV-2 infection developed did not differ significantly from that in the placebo group, with risk reductions relative to placebo of 29.8% (95% confidence interval [CI], -16.7 to 57.8; P = 0.17) in the 5-day nirmatrelvir-ritonavir group and 35.5% (95% CI, -11.5 to 62.7; P = 0.12) in the 10-day nirmatrelvir-ritonavir group. The incidence of adverse events was similar across the trial groups, with dysgeusia being the most frequently reported adverse event (in 5.9% and 6.8% of the participants in the 5-day and 10-day nirmatrelvir-ritonavir groups, respectively, and in 0.7% of those in the placebo group). CONCLUSIONS: In this placebo-controlled trial, postexposure prophylaxis with nirmatrelvir-ritonavir for 5 or 10 days did not significantly reduce the risk of symptomatic SARS-CoV-2 infection.

Probable paralytic rabies in a dog: ante-mortem clinical diagnosis implications in limited resource settings.

INTRODUCTION: Rabies is a dreadful zoonotic viral disease that affects animals and humans with a fatality rate of 100%. This report aims to create awareness among the veterinarians and general public about the paralytic form of rabies in order to understand the antemortem clinical diagnosis implications in limited resource settings, so as to follow the post-exposure prophylaxis at the golden hour period of rabies transmission. CASE PRESENTATION: A one-year-old female dog was presented to the Ambulatory Clinic Unit, Veterinary Clinical Complex, Veterinary College and Research Institute, Theni, Tamil Nadu, India with the ailment of a dropped jaw and was unable to swallow food and water for the past three days. Epidemiological investigations revealed that the animal had dog-bitten wounds from a week ago. On clinical examination, facial distortion, changes in the vocal cord, and paralysis of the throat muscle were noticed. Based on the anamnesis, clinical, and epidemiological investigations, the animal was diagnosed to be a probable case of paralytic form of canine rabies. In the limited resource settings, antemortem clinical diagnosis was practiced to suspect rabies-infected dogs. Further, the owner was advised to implement preventive measures to safeguard against rabies infection. The dog was kept under isolation and succumbed on day two with evidence of progressive paralytic signs. CONCLUSIONS: This report emphasizes the importance of paralytic rabies, alongside of furious form of rabies, further creating awareness among the general public about the antemortem clinical diagnosis under limited resource settings.

Spatial accessibility and inequality analysis of rabies-exposed patients to rabies post-exposure prophylaxis clinics in Guangzhou City, China.

BACKGROUND: The incidence of rabies exposure is high and increasing in China, leading to an urgent demand of rabies post-exposure prophylaxis (PEP) clinics for the injured. However, the spatial accessibility and inequality of rabies-exposed patients to rabies PEP clinics is less known in China. METHODS: Based on rabies exposure data, PEP clinic data, and resident travel origin-destination (OD) matrix data in Guangzhou City, China, we first described the incidence of rabies exposure in Guangzhou from 2020 to 2022. Then, the Gaussian two-step floating catchment area method (2SFCA) was used to analyze the spatial accessibility of rabies-exposed patients to rabies PEP clinics in Guangzhou, and the Gini coefficient and Moran's I statistics were utilized to evaluate the inequality and clustering of accessibility scores. RESULTS: From 2020 to 2022, a total of 524,160 cases of rabies exposure were reported in Guangzhou, and the incidence showed a significant increasing trend, with an average annual incidence of 932.0/100,000. Spatial accessibility analysis revealed that the overall spatial accessibility scores for three scenarios (threshold of driving duration [d0] = 30 min, 45 min, and 60 min) were 0.30 (95% CI: 0.07, 0.87), 0.28 (95% CI: 0.11, 0.53) and 0.28 (95% CI: 0.14, 0.44), respectively. Conghua, Huangpu, Zengcheng and Nansha districts had the higher accessibility scores, while Haizhu, Liwan, and Yuexiu districts exhibited lower spatial accessibility scores. The Gini coefficient and Moran's I statistics showed that there were certain inequality and clustering in the accessibility to rabies PEP clinics in Guangzhou. CONCLUSIONS: This study clarifies the heterogeneity of spatial accessibility to rabies PEP clinics, and provide valuable insights for resource allocation to achieve the WHO target of zero human dog-mediated rabies deaths by 2030.

A noninferiority randomized open-label pilot study of 3- versus 7-day influenza postexposure prophylaxis with oseltamivir in hospitalized children.

Short influenza postexposure prophylaxis (PEP) showed high efficacy in adults, but studies in children are lacking. This randomized open-label pilot trial aimed to verify noninferiority of a 3- versus 7-day prophylaxis with oral oseltamivir in hospitalized children. Influenza contacts were randomized to the 3- or 7-day group and efficacy, relative risk of adverse events (AEs), and the cumulative costs of drugs and AEs management were compared. The intention-to-treat (ITT) analysis included 59 children (n = 28 and n = 31 in the 3- and 7-day group, respectively). The efficacy was 100% (95% CI 87.7-100%) versus 93.6% (95% CI 78.6-99.2%) in the 3- and 7-day group; the differences were statistically insignificant. A per-protocol (PP) analysis including 56 patients (n = 27 and n = 29, respectively) showed 100% (95% CI 87.2-100%) and 93.1% (95% CI 77.2-99.2%) efficacy, respectively, without statistical significance. Differences were within the predefined noninferiority margin with an efficacy difference Δ = 6.45 percentage points (p.p.) with 1-sided 95% CI (- 2.8, - 1.31, p = 0.86; ITT) and Δ = 6.9 p.p. (1-sided 95% CI - 2.83, - 1.27, p = 0.85; PP). Adverse events did not differ significantly, while the cumulative costs of the prophylaxis and AEs management were higher in the 7-day group (median 10.5 euro vs. 4.5 euro, p < 0.01). This pilot study showed the noninferiority of the 3-day versus 7-day PEP, which was associated with lower costs.Trial registration number: NCT04297462, 5th March 2020, restrospectively registered.

Safety and adherence of bictegravir/emtricitabine/tenofovir alafenamide for HIV post-exposure prophylaxis among adults in Guiyang China: a prospective cohort study.

BACKGROUND: The effectiveness of post-exposure prophylaxis (PEP) depends on participants adherence, making it crucial to assess and compare regimen options to enhance human immunodeficiency virus (HIV) prophylaxis strategies. However, no prospective study in China has shown that the completion rate and adherence of single-tablet regimens in HIV PEP are higher than those of multi-tablet preparations. Therefore, this study aimed to assess the completion rate and adherence of two HIV PEP regimens. METHODS: In this single-center, prospective, open-label cohort study, we included 179 participants from May 2022 to March 2023 and analyzed the differences in the 28-day medication completion rate, adherence, safety, tolerance, and effectiveness of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) and tenofovir disoproxil fumarate, emtricitabine, and dolutegravir (TDF/FTC + DTG). RESULTS: The PEP completion rate and adherence were higher in the BIC/FTC/TAF group than in the TDF/FTC + DTG group (completion rate: 97.8% vs. 82.6%, P = 0.009; adherence: 99.6 ± 2.82% vs. 90.2 ± 25.29%, P = 0.003). The incidence of adverse reactions in the BIC/FTC/TAF and TDF/FTC + DTG groups was 15.2% and 10.3% (P = 0.33), respectively. In the TDF/FTC + DTG group, one participant stopped PEP owing to adverse reactions (1.1%). No other participants stopped PEP due to adverse events. CONCLUSIONS: BIC/FTC/TAF and TDF/FTC + DTG have good safety and tolerance as PEP regimens. BIC/FTC/TAF has a higher completion rate and increased adherence, thus, is recommended as a PEP regimen. These findings emphasize the importance of regimen choice in optimizing PEP outcomes. TRIAL REGISTRATION: The study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR2200059994(2022-05-14), https://www.chictr.org.cn/bin/project/edit?pid=167391 ).

CDC Clinical Guidelines on the Use of Doxycycline Postexposure Prophylaxis for Bacterial Sexually Transmitted Infection Prevention, United States, 2024.

No vaccines and few chemoprophylaxis options exist for the prevention of bacterial sexually transmitted infections (STIs) (specifically syphilis, chlamydia, and gonorrhea). These infections have increased in the United States and disproportionately affect gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW). In three large randomized controlled trials, 200 mg of doxycycline taken within 72 hours after sex has been shown to reduce syphilis and chlamydia infections by >70% and gonococcal infections by approximately 50%. This report outlines CDC's recommendation for the use of doxycycline postexposure prophylaxis (doxy PEP), a novel, ongoing, patient-managed biomedical STI prevention strategy for a selected population. CDC recommends that MSM and TGW who have had a bacterial STI (specifically syphilis, chlamydia, or gonorrhea) diagnosed in the past 12 months should receive counseling that doxy PEP can be used as postexposure prophylaxis to prevent these infections. Following shared decision-making with their provider, CDC recommends that providers offer persons in this group a prescription for doxy PEP to be self-administered within 72 hours after having oral, vaginal, or anal sex. The recommended dose of doxy PEP is 200 mg and should not exceed a maximum dose of 200 mg every 24 hours.Doxy PEP, when offered, should be implemented in the context of a comprehensive sexual health approach, including risk reduction counseling, STI screening and treatment, recommended vaccination and linkage to HIV PrEP, HIV care, or other services as appropriate. Persons who are prescribed doxy PEP should undergo bacterial STI testing at anatomic sites of exposure at baseline and every 3-6 months thereafter. Ongoing need for doxy PEP should be assessed every 3-6 months as well. HIV screening should be performed for HIV-negative MSM and TGW according to current recommendations.

Postexposure prophylaxis for occupational exposure to selected pathogens for healthcare personnel.

PURPOSE OF REVIEW: Timely postexposure prophylaxis is important after an occupational exposure. Here we review select organisms, exposure opportunities in the healthcare setting, and postexposure prophylaxis regimens. RECENT FINDINGS: Needlestick injuries pose a risk of exposure to bloodborne pathogens, such as HIV, Hepatitis B, and Hepatitis C. Risk mitigation strategies should be reexamined in light of newer vaccines and therapeutics. Increased vaccine hesitancy and vaccine denialisms may foster the re-emergence of some infections that have become extremely uncommon because of effective vaccines. With increasing occurrences of zoonotic infections and the ease of global spread as evidenced by COVID-19 and mpox, healthcare exposures must also consider risks related to emerging and re-emerging infectious diseases. SUMMARY: Early recognition and reporting of occupational exposures to pathogens with available postexposure prophylaxis is key to mitigating the risk of transmission. Providers should be able to evaluate the exposure and associated risks to provide prompt and appropriate postexposure prophylaxis.

Bat Bites and Rabies PEP in the Croatian Reference Centre for Rabies 1995-2020.

Seroprevalence of lyssaviruses in certain bat species has been proven in the Republic of Croatia, but there have been no confirmed positive bat brain isolates or human fatalities associated with bat injuries/bites. The study included a retrospective analysis of bat injuries/bites, post-exposure prophylaxis (PEP) and geographic distribution of bat injuries in persons examined at the Zagreb Antirabies Clinic, the Croatian Reference Centre for Rabies. In the period 1995-2020, we examined a total of 21,910 patients due to animal injuries, of which 71 cases were bat-related (0.32%). Of the above number of patients, 4574 received rabies PEP (20.87%). However, for bat injuries, the proportion of patients receiving PEP was significantly higher: 66 out of 71 patients (92.95%). Of these, 33 received only the rabies vaccine, while the other 33 patients received the vaccine with human rabies immunoglobulin (HRIG). In five cases, PEP was not administered, as there was no indication for treatment. Thirty-five of the injured patients were biologists or biology students (49.29%). The bat species was confirmed in only one of the exposure cases. This was a serotine bat (Eptesicus serotinus), a known carrier of Lyssavirus hamburg. The results showed that the bat bites were rather sporadic compared to other human injuries caused by animal bites. All bat injuries should be treated as if they were caused by a rabid animal, and according to WHO recommendations. People who come into contact with bats should be strongly advised to be vaccinated against rabies. Entering bat habitats should be done with caution and in accordance with current recommendations, and nationwide surveillance should be carried out by competent institutions and in close collaboration between bat experts, epidemiologists and rabies experts.

A unifying model to explain frequent SARS-CoV-2 rebound after nirmatrelvir treatment and limited prophylactic efficacy.

In a pivotal trial (EPIC-HR), a 5-day course of oral ritonavir-boosted nirmatrelvir, given early during symptomatic SARS-CoV-2 infection (within three days of symptoms onset), decreased hospitalization and death by 89.1% and nasal viral load by 0.87 log relative to placebo in high-risk individuals. Yet, nirmatrelvir/ritonavir failed as post-exposure prophylaxis in a trial, and frequent viral rebound has been observed in subsequent cohorts. We develop a mathematical model capturing viral-immune dynamics and nirmatrelvir pharmacokinetics that recapitulates viral loads from this and another clinical trial (PLATCOV). Our results suggest that nirmatrelvir's in vivo potency is significantly lower than in vitro assays predict. According to our model, a maximally potent agent would reduce the viral load by approximately 3.5 logs relative to placebo at 5 days. The model identifies that earlier initiation and shorter treatment duration are key predictors of post-treatment rebound. Extension of treatment to 10 days for Omicron variant infection in vaccinated individuals, rather than increasing dose or dosing frequency, is predicted to lower the incidence of viral rebound significantly.

Navigating Barriers and Opportunities: Perceptions of the Non-Occupational Post-Exposure Prophylaxis Care Continuum Among Young Sexual Minority Men, Aged 17-24, in the United States.

Human immunodeficiency virus (HIV) is a public health concern among young sexual minority men (YSMM), ages 17 to 24, in the United States. Biomedical prevention methods, such as pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP), can help reduce the risk of HIV transmission among this population. However, there is limited awareness and use of nPEP by YSMM. This study aims to explore the perceptions of YSMM regarding the nPEP care continuum, which consists of three areas of focus: awareness, uptake, and linkage to other HIV prevention services. This study draws on synchronous online focus groups with a sample of 41 YSMM in the United States. Transcripts from the focus groups were analyzed using reflexive thematic analysis. Participants reported limited nPEP awareness and prior use, a process of personal appraisal of nPEP need based on HIV risk and costs, and a preference for PrEP over PEP for long-term HIV prevention. Interventions should be tailored to increase awareness of nPEP among YSMM and reduce addressable barriers to nPEP use for YSMM, including cost and confidentiality concerns, in situations where nPEP is warranted. Finally, more research is needed on how nPEP use can act as a bridge to PrEP initiation for this population.
