RESUMEN
HIV genotyping is used to assess HIV susceptibility to antiretroviral drugs. The Applied Biosystems HIV-1 Genotyping Kit with Integrase (AB kit, Thermo Fisher Scientific) detects resistance-associated mutations (RAMs) in HIV protease (PR), reverse transcriptase (RT), and integrase (IN). We compared results from the AB kit with results obtained previously with the ViroSeq HIV-1 Genotyping System. DNA amplicons from the AB kit were also analyzed using next-generation sequencing (NGS). HIV RNA was extracted using the MagNA Pure 24 instrument (Roche Diagnostics; 96 plasma samples, HIV subtype B, viral load range: 530-737,741 copies/mL). FASTA files were generated from AB kit data using Exatype (Hyrax Biosciences). DNA amplicons from the AB kit were also analyzed by NGS using the Nextera XT kit (Illumina). Drug resistance was predicted using the Stanford HIV Drug Resistance Database. The mean genetic distance for sequences from ViroSeq and the AB kit was 0.02% for PR/RT and 0.04% for IN; 103 major RAMs were detected by both methods. Four additional major RAMs were detected by the AB kit only. These four major RAMs were also detected by NGS (detected in 18.1%-38.2% of NGS reads). NGS detected 27 major RAMs that were not detected with either of the Sanger sequencing-based kits. All major RAMs detected with ViroSeq were detected with the AB kit; additional RAMs were detected with the AB kit only. DNA amplicons from the AB kit can be used for NGS for more sensitive detection of RAMs.

After nearly a decade of HIV pre-exposure prophylaxis (PrEP) rollout in sub-Saharan Africa, there has been limited study of PrEP messaging in news media. We selected twenty South African newspapers with the highest circulation volumes to retrieve articles published in 2012-2021 mentioning PrEP (N = 249). Using inductive content analysis, we developed a structured codebook to characterise PrEP-related content and sentiments, as well as their evolution over time, in the South African press. Many articles espoused favourable attitudes towards PrEP (52%), but a sizeable fraction espoused unfavourable attitudes (11%). Relative to PrEP-favourable articles, PrEP-unfavourable articles were significantly more likely to emphasise the drawbacks/consequences of PrEP use, including adherence/persistence requirements (52% vs. 24%, p = .007), cost (48% vs. 11%, p < .001), and risk compensation (52% vs. 5%, p < .001). Nevertheless, the presence of these drawbacks/consequences in print media largely declined over time. Key populations (e.g. adolescents, female sex workers) were frequently mentioned potential PrEP candidates. Despite message variations over time, prevention effectiveness and adherence/persistence requirements were the most widely cited PrEP benefits and drawbacks, respectively. Study findings demonstrate the dynamic nature of PrEP coverage in the South African press, likely in response to PrEP scale-up and real-world PrEP implementation during the study period.
RESUMEN
Background: Adult studies have demonstrated that polysubstance use increases HIV acquisition risk through increased sexual behaviors, however, few studies have examined polysubstance in young Black and Latinx sexual minority men (SMM) and transgender women (TW). Methods: We used cross-sectional data from 466 young Black and Latinx SMM and TW living in four high HIV-burden US cities enrolled in the PUSH Study, a status-neutral randomized control trial to increase HIV prevention and treatment adherence. We examined data for patterns of polysubstance use comparing age differences of use and explored associations between substance use and sexual partnership factors - inconsistent condom use, pressure to have condomless anal sex, and older partner, using bivariate and multivariate analyses. Results: Most participants described prior substance use with alcohol and cannabis being most common (76% each) and 23% described other illicit drug use, including stimulants, cocaine, hallucinogens, sedatives, opioids, and inhalants. Polysubstance use was common with nearly half (47%) of participants reporting alcohol and cannabis use, 20% reporting alcohol, cannabis, and one other illicit drug use, and 19% reporting alcohol or cannabis use plus one other illicit drug use. Polysubstance use was associated with greater adjusted odds of pressure to have condomless anal sex, older partner (>5 years older), and inconsistent condom use. Conclusions: Associations of polysubstance use with sexual practices and sexual partnerships that are known predictors of HIV acquisition or transmission among Black and Latinx SMM and TW underscore the need for combination interventions that include substance use treatment alongside antiretroviral-based and partner-based HIV prevention and treatment interventions.Trial Registration: ClinicalTrials.gov Identifier: NCT03194477.

The plan for Ending the HIV (human immunodeficiency virus) Epidemic (EHE) in the United States aims to reduce new infections by 75% by 2025 and by 90% by 2030. For EHE to be successful, it is important to accurately measure changes in numbers of new HIV infections after 5 and 10 years (to determine whether the EHE goals have been achieved) but also over shorter timescales (to monitor progress and intensify prevention efforts if required). In this viewpoint, we aim to demonstrate why the method used to monitor progress toward the EHE goals must be carefully considered. We briefly describe and discuss different methods to estimate numbers of new HIV infections based on longitudinal cohort studies, cross-sectional incidence surveys, and routine surveillance data. We particularly focus on identifying conditions under which unadjusted and adjusted estimates based on routine surveillance data can be used to estimate changes in new HIV infections.

The opioid epidemic is one of the greatest public health problems that the USA faces. Opioid overdose death rates have increased steadily for more than a decade and doubled in 2013-17, as the highly potent synthetic opioid fentanyl entered the drug supply. Demographics of new HIV diagnoses among people who inject drugs are also changing, with more new HIV diagnoses occurring among White people, young people (aged 13-34 years), and people who reside outside large central metropolitan areas. Racial differences also exist in syringe sharing, which decreased among Black people and Hispanic people but remained unchanged among White people in 2005-15. Recent HIV outbreaks have occurred in rural areas of the USA, as well as among marginalised people in urban areas with robust HIV prevention and treatment services (eg, Seattle, WA). Multiple evidence-based interventions can effectively treat opioid use disorder and prevent HIV acquisition. However, considerable barriers exist precluding delivery of these solutions to many people who inject drugs. If the USA is serious about HIV prevention among this group, stigma must be eliminated, discriminatory policies must change, and comprehensive health care must be accessible to all. Finally, root causes of the opioid epidemic such as hopelessness need to be identified and addressed.

With more than 1·2 million people living with HIV in the USA, a complex epidemic across the large and diverse country, and a fragmented health-care system marked by widening health disparities, the US HIV epidemic requires sustained scientific and public health attention. The epidemic has been stubbornly persistent; high incidence densities have been sustained over decades and the epidemic is increasingly concentrated among racial, ethnic, and sexual and gender minority communities. This fact remains true despite extraordinary scientific advances in prevention, treatment, and care-advances that have been led, to a substantial degree, by US-supported science and researchers. In this watershed year of 2021 and in the face of the COVID-19 pandemic, it is clear that the USA will not meet the stated goals of the National HIV/AIDS Strategy, particularly those goals relating to reductions in new infections, decreases in morbidity, and reductions in HIV stigma. The six papers in the Lancet Series on HIV in the USA have each examined the underlying causes of these challenges and laid out paths forward for an invigorated, sustained, and more equitable response to the US HIV epidemic than has been seen to date. The sciences of HIV surveillance, prevention, treatment, and implementation all suggest that the visionary goals of the Ending the HIV Epidemic initiative in the USA might be achievable. However, fundamental barriers and challenges need to be addressed and the research effort sustained if we are to succeed.

The HIV epidemic in the USA began as a bicoastal epidemic focused in large cities but, over nearly four decades, the epidemiology of HIV has changed. Public health surveillance data can inform an understanding of the evolution of the HIV epidemic in terms of the populations and geographical areas most affected. We analysed publicly available HIV surveillance data and census data to describe: current HIV prevalence and new HIV diagnoses by region, race or ethnicity, and age; trends in HIV diagnoses over time by HIV acquisition risk and age; and the distribution of HIV prevalence by geographical area. We reviewed published literature to explore the reasons for the current distribution of HIV cases and important disparities in HIV prevalence. We identified opportunities to improve public health surveillance systems and uses of data for planning and monitoring public health responses. The current US HIV epidemic is marked by geographical concentration in the US South and profound disparities between regions and by race or ethnicity. Rural areas vary in HIV prevalence; rural areas in the South are more likely to have a high HIV prevalence than rural areas in other US Census regions. Ongoing disparities in HIV in the South are probably driven by the restricted expansion of Medicaid, health-care provider shortages, low health literacy, and HIV stigma. HIV diagnoses overall declined in 2009-18, but HIV diagnoses among individuals aged 25-34 years increased during the same period. HIV diagnoses decreased for all risk groups in 2009-18; among men who have sex with men (MSM), new diagnoses decreased overall and for White MSM, remained stable for Black MSM, and increased for Hispanic or Latino MSM. Surveillance data indicate profound and ongoing disparities in HIV cases, with disproportionate impact among people in the South, racial or ethnic minorities, and MSM.

Men who have sex with men (MSM) in the USA were the first population to be identified with AIDS and continue to be at very high risk of HIV acquisition. We did a systematic literature search to identify the factors that explain the reasons for the ongoing epidemic in this population, using a social-ecological perspective. Common features of the HIV epidemic in American MSM include role versatility and biological, individual, and social and structural factors. The high-prevalence networks of some racial and ethnic minority men are further concentrated because of assortative mixing, adverse life experiences (including high rates of incarceration), and avoidant behaviour because of negative interactions with the health-care system. Young MSM have additional risks for HIV because their impulse control is less developed and they are less familiar with serostatus and other risk mitigation discussions. They might benefit from prevention efforts that use digital technologies, which they often use to meet partners and obtain health-related information. Older MSM remain at risk of HIV and are the largest population of US residents with chronic HIV, requiring culturally responsive programmes that address longer-term comorbidities. Transgender MSM are an understudied population, but emerging data suggest that some are at great risk of HIV and require specifically tailored information on HIV prevention. In the current era of pre-exposure prophylaxis and the undetectable equals untransmittable campaign, training of health-care providers to create culturally competent programmes for all MSM is crucial, since the use of antiretrovirals is foundational to optimising HIV care and prevention. Effective control of the HIV epidemic among all American MSM will require scaling up programmes that address their common vulnerabilities, but are sufficiently nuanced to address the specific sociocultural, structural, and behavioural issues of diverse subgroups.

Intimate partner violence (IPV) has been implicated in HIV acquisition and worse HIV outcomes. Limited research focuses on the experiences of Black gay and bisexual men. Using data from cross-sectional surveys in Baltimore, Maryland, and Jackson, Mississippi, we analyzed the association between IPV victimization and HIV-related outcomes among 629 adult Black gay and bisexual men, among whom 53% self-reported a negative result at last HIV test. 40% of participants reported lifetime physical, sexual, and/or psychological IPV victimization, and 24% past-year victimization. Recent and lifetime IPV were associated with recent clinical diagnosis of STI (adjPrR: 1.44; 95%CI: 1.08-1.92) and ART medication interruptions (adjPrR: 1.59; 95%CI: 1.25-2.01), respectively. Physical IPV was inversely associated with current PrEP use (adjPrR: 0.35; 95%CI: 0.13-0.90). Recent IPV was independently correlated with depression symptomatology (adjPrR: 2.36; 95%CI: 1.61-3.47) and hazardous alcohol use (adjPrR: 1.93; 95%CI: 1.42-2.61), with evidence of interactions. IPV-HIV relationships were intersected by internalized stigma, housing instability, poverty, and lack of insurance. Tailored IPV services are urgently needed for comprehensive HIV services for Black gay and bisexual men in the U.S.

Adherence to care and antiretroviral therapy is challenging, especially for people living with HIV (PLWH) with additional co-occurring risk factors. Case management interventions, including motivational interviewing (MI), show promise to improve HIV treatment adherence, but few studies have examined how such interventions are delivered to or experienced by PLWH who have been reengaged in care. We conducted qualitative interviews with six case managers and 110 PLWH exiting from a randomized study (HPTN 078) who received a MI-based case management intervention in addition to standard patient-navigation services, or standard services only. Our study provided greater insight into the main findings from HPTN 078, including an in-depth description of the multiple barriers to adherence faced by this largely "out-of-care" population, as well as a more nuanced understanding of the benefits and challenges of implementing MI. A blend of MI plus more intensive interventions may be needed for PLWH facing multiple structural barriers.

HIV self-testing (HIVST) shows promise to improve HIV diagnosis among those seeking privacy and anonymity in HIV testing. This may include sexual and gender diverse populations, who experience disproportionately high burdens of stigma and HIV globally. To inform potential scale-up of HIVST in Myanmar, we implemented a community-led, mixed-methods randomized trial in Yangon. Adult trans-feminine individuals and cisgender men who have sex with men were recruited via respondent-driven sampling. Participants (N = 577) completed a baseline survey and were randomized to community-based HIV testing services (HTS) or HIVST. One-third of participants reported lifetime HIV testing. Over half (59.4%) returned for a second study visit to report their test result and test acceptability, which was lower among HTS-assigned participants compared to those assigned to HIVST (55.6% vs. 63.1%; p = 0.096). Participants reported that both HIVST and HTS were easy to access, test, and interpret/understand the results of their HIV test. Ninety percent of HTS-assigned participants indicated they would test regularly if they could access HIVST. Qualitative participants (N = 20) described that the convenience and privacy afforded by HIVST may increase the availability and coverage of testing. Taken together, these results suggest HIVST is an acceptable, low-barrier complement to community-based HTS for key populations in Myanmar.

HIV incidence is high and persistent among cisgender men who have sex with men (MSM) and transgender women (TGW) who have sex with men, particularly among those who sell or trade sex. In preparation for an open-label combination HIV pre-exposure prophylaxis (PrEP) program for these groups, we conducted formative research to explore the context of sex work/trade and factors that affect implementation of PrEP interventions. This study analyzed interviews with 20 young (aged 18-26 years) MSM and TGW who sell/trade sex and three sex work venue managers in Bangkok and Pattaya, Thailand. Participants described diverse contexts of sex work/trade, including in multiple informal and formal sex venues. Several participants reported mobility across provinces and out of the country, which led to intermittent sex work/trade. TGW sex workers reported challenges with access and cost of femininizing hormones and limited employment opportunities. Factors that could facilitate or challenge PrEP program implementation included HIV stigma, the role of venue management in sexual health practice, lack of PrEP knowledge, lower perceived HIV risk, and interest in personal health and wellbeing. Program implementers must consider myriad factors to successfully implement PrEP among young MSM and TGW engaged in sex work or trade in Thailand.

BACKGROUND: Sexual transmission of hepatitis C virus (HCV) is uncommon, yet documented among men who have sex with men (MSM), primarily among those with human immunodeficiency virus (HIV). METHODS: In the HIV Prevention Trials Network 078 study (HPTN 078), which assessed an integrated strategy to achieve HIV viral suppression, 1305 MSM were screened across 4 geographically diverse US cities. At screening, demographic/behavioral/psychosocial questionnaires were completed, along with HIV and HCV testing. Multivariable logistic regression was used to evaluate associations with HCV antibody positivity. RESULTS: Among the 1287 (99%) of the MSM with HCV antibody results, the median age was 41, 69% were black, 85% had a high school education or more, 35% were employed, 70% had HIV, and 21% had undergone substance use counseling. The median lifetime number of male sexual partners was 17 (interquartile range, 6-50), and 246 (19%) were HCV antibody positive. HCV antibody positivity was high in MSM with HIV (20%) and MSM without HIV (17%) (P = .12) and was higher in those receiving substance use counseling (36%) than in those who had not (15%) (P ≤ .01). Substance use counseling (odds ratio, 2.51; 95% confidence interval, 1.80-3.51) and unstable housing (2.16; 1.40-3.33) were associated with HCV antibody positivity. CONCLUSIONS: Nearly 1 in 5 MSM screened for HPTN 078 have been infected with HCV. The prevalence is high regardless of HIV status and is high even in those who did not undergo substance use counseling. In HIV burden networks, high HCV infection prevalence may occur in MSM without HIV. As implementation of preexposure prophylaxis expands and condom use declines, routine HCV counseling and screening among MSM are important.

There is an urgent need to measure the impacts of COVID-19 among gay men and other men who have sex with men (MSM). We conducted a cross-sectional survey with a global sample of gay men and other MSM (n = 2732) from April 16, 2020 to May 4, 2020, through a social networking app. We characterized the economic, mental health, HIV prevention and HIV treatment impacts of COVID-19 and the COVID-19 response, and examined whether sub-groups of our study population are disproportionately impacted by COVID-19. Many gay men and other MSM not only reported economic and mental health consequences, but also interruptions to HIV prevention and testing, and HIV care and treatment services. These consequences were significantly greater among people living with HIV, racial/ethnic minorities, immigrants, sex workers, and socio-economically disadvantaged groups. These findings highlight the urgent need to mitigate the negative impacts of COVID-19 among gay men and other MSM.
RESUMEN: Existe una necesidad urgente para medir los impactos de COVID-19 entre hombres gay y otros hombres que tienen sexo con hombres (HSH). Hemos conducido una encuesta multifuncional con una prueba mundial de hombres gay y otros HSH (n = 2732) desde el 16 de Abril hasta el 4 de Mayo del 2020, a través de una aplicación de red social. Nosotros caracterizamos los impactos económicos, de salud mental, prevención del VIH y tratamiento del VIH e impactos a COVID-19 y la respuesta de COVID-19, y examinamos si subgrupos de nuestra población de estudio fueron impactados desproporcionadamente por COVID-19. Muchos hombres no tan solo reportaron consecuencias económicas y de salud mental, sino también interrupciones de prevención y de pruebas de VIH, y cuidado del VIH y servicios de tratamiento. Encontramos consecuencias más significantes entre personas viviendo con VIH, grupos raciales/etnicos, migrantes, sexo servidores, y groupos socioeconomicamente disfavorecidos. Los resultados subrayan la necesidad crucial de mitigar los impactos multifacéticos de COVID-19 entre los hombres homosexuales y otros HSH, especialmente para aquellos con vulnerabilidades entrelazadas.

BACKGROUND: In Rwanda, epidemiological data characterizing people who inject drugs (PWID) and their burden of HIV are limited. We examined injection drug use (IDU) history and practices, and HIV infection in a sample of PWID in Kigali. METHODS: From October 2019 to February 2020, 307 PWID aged ≥ 18 were enrolled in a cross-sectional study using convenience sampling in Kigali. Participants completed interviewer-administered questionnaires on IDU history and practices and HIV testing. We used Poisson regression with robust variance estimation to assess IDU practices associated with HIV infection and assessed factors associated with needle sharing in the six months preceding the study. RESULTS: The median age was 28 years (IQR 24-31); 81% (251) were males. Female PWID were more likely to report recent IDU initiation, selling sex for drugs, and to have been injected by a sex partner (p < 0.05). In the prior six months, heroin was the primary drug of choice for 99% (303) of participants, with cocaine and methamphetamine also reported by 10% (31/307) and 4% (12/307), respectively. In total, 91% (280/307) of participants reported ever sharing needles in their lifetime and 43% (133) knew someone who died from a drug-related overdose. HIV prevalence was 9.5% (95% CI 8.7-9.3). Sharing needles at least half of the time in the previous six months was positively associated with HIV infection (adjusted prevalence ratio (aPR) 2.67; 95% CI 1.23-5.78). Overall, 31% (94/307) shared needles and 33% (103/307) reused needles in the prior six months. Female PWID were more likely to share needles compared to males (aPR 1.68; 95% CI 1.09-2.59). Additionally, bisexual PWID (aPR 1.68; 95% CI 1.09-2.59), those who shared needles at the first injection (aPR 2.18; 95% CI 1.59-2.99), reused needles recently (aPR 2.27; 95% CI 1.51-3.43) and shared other drug paraphernalia (aPR 3.56; 95% CI 2.19-5.81) were more likely to report recent needle sharing. CONCLUSION: HIV infection was common in this study. The high prevalence of needle reuse and sharing practices highlights significant risks for onward transmission and acquisition of HIV and viral hepatitis. These data highlight the urgent need for PWID-focused harm reduction services in Rwanda, including syringe services programs, safe injection education, naloxone distribution, and substance use disorder treatment programs and optimizing these services to the varied needs of people who use drugs in Rwanda.

Intimate Partner Violence (IPV) is a prevalent, but underrecognized issue among sexual minorities (SM) broadly, but especially among Black Gay and Bisexual Men (BGBM). Over the last several years, acts of IPV among BGBM made national news, drawing attention to the unique ways that IPV plays out within this particular population. Yet, little research has examined the intersections between race and sexuality among BGBM, the lack of culturally responsive IPV services, their support needs, or the barriers that BGBM face when seeking IPV related services. When examined closely, the field of IPV has traditionally focused on cisgender heterosexual white woman as victims and cisgender white men as perpetrators, which has historically impacted the availability and quality of IPV services for other populations. This narrative critique of the IPV movement calls for an intersectional social justice and health equity approach to address the unique and intersectional needs of BGBM who experience IPV. By centering the intersectional needs of BGBM and the role that racism, homophobia, and heteronormative has played in shaping IPV-related services, this article challenges the IPV field to advance a social justice orientation in order to address the unmet needs of BGBM who experience IPV.
RESUMEN
The economic crisis in Venezuela has eroded the country's health-care infrastructure and threatened the public health of its people. Shortages in medications, health supplies, interruptions of basic utilities at health-care facilities, and the emigration of health-care workers have led to a progressive decline in the operational capacity of health care. The effect of the crisis on public health has been difficult to quantify since the Venezuelan Ministry of Health stopped publishing crucial public health statistics in 2016. We prepared a synthesis of health information, beyond what is available from other sources, and scholarly discussion of engagement strategies for the international community. Data were identified through searches in MEDLINE, PubMed, and the grey literature, through references from relevant articles, and governmental and non-governmental reports, and publicly available databases. Articles published in English and Spanish until Dec 1, 2018, were included. Over the past decade, public health measures in Venezuela have substantially declined. From 2012 to 2016, infant deaths increased by 63% and maternal mortality more than doubled. Since 2016, outbreaks of the vaccine-preventable diseases measles and diphtheria have spread throughout the region. From 2016 to 2017, Venezuela had the largest rate of increase of malaria in the world, and in 2015, tuberculosis rates were the highest in the country in 40 years. Between 2017 and 2018, most patients who were infected with HIV interrupted therapy because of a lack of medications. The Venezuelan economic crisis has shattered the health-care system and resulted in rising morbidity and mortality. Outbreaks and expanding epidemics of infectious diseases associated with declines in basic public health services are threatening the health of the country and the region.

OBJECTIVES: To evaluate the performance of a high-throughput research assay for HIV drug resistance testing based on whole genome next-generation sequencing (NGS) that also quantifies HIV viral load. METHODS: Plasma samples (n = 145) were obtained from HIV-positive MSM (HPTN 078). Samples were analysed using clinical assays (the ViroSeq HIV-1 Genotyping System and the Abbott RealTime HIV-1 Viral Load assay) and a research assay based on whole-genome NGS (veSEQ-HIV). RESULTS: HIV protease and reverse transcriptase sequences (n = 142) and integrase sequences (n = 138) were obtained using ViroSeq. Sequences from all three regions were obtained for 100 (70.4%) of the 142 samples using veSEQ-HIV; results were obtained more frequently for samples with higher viral loads (93.5% for 93 samples with >5000â copies/mL; 50.0% for 26 samples with 1000-5000â copies/mL; 0% for 23 samples with <1000â copies/mL). For samples with results from both methods, drug resistance mutations (DRMs) were detected in 33 samples using ViroSeq and 42 samples using veSEQ-HIV (detection threshold: 5.0%). Overall, 146 major DRMs were detected; 107 were detected by both methods, 37 were detected by veSEQ-HIV only (frequency range: 5.0%-30.6%) and two were detected by ViroSeq only. HIV viral loads estimated by veSEQ-HIV strongly correlated with results from the Abbott RealTime Viral Load assay (R2 = 0.85; n = 142). CONCLUSIONS: The NGS-based veSEQ-HIV method provided results for most samples with higher viral loads, was accurate for detecting major DRMs, and detected mutations at lower levels compared with a method based on population sequencing. The veSEQ-HIV method also provided HIV viral load data.

Although the benefit of population-level public facial masking to protect others during the COVID-19 pandemic has received a great deal of attention, we discuss for one of the first times the hypothesis that universal masking reduces the "inoculum" or dose of the virus for the mask-wearer, leading to more mild and asymptomatic infection manifestations. Masks, depending on type, filter out the majority of viral particles, but not all. We first discuss the near-century-old literature around the viral inoculum and severity of disease (conceptualized as the LD50 or lethal dose of the virus). We include examples of rising rates of asymptomatic infection with population-level masking, including in closed settings (e.g., cruise ships) with and without universal masking. Asymptomatic infections may be harmful for spread but could actually be beneficial if they lead to higher rates of exposure. Exposing society to SARS-CoV-2 without the unacceptable consequences of severe illness with public masking could lead to greater community-level immunity and slower spread as we await a vaccine. This theory of viral inoculum and mild or asymptomatic disease with SARS-CoV-2 in light of population-level masking has received little attention so this is one of the first perspectives to discuss the evidence supporting this theory.
