The coronavirus disease 2019 pandemic has placed substantial strain on the global health care workforce, disrupting essential and nonessential services. Task sharing of test and treat services to nontraditional prescribers, such as pharmacists, can facilitate more resilient health care systems by expanding access to health services while simultaneously decreasing the pressure on traditional health care providers. Expansion of pharmacists' scope of work has historically been hindered by sociopolitical, resourcing, and competency considerations; addressing these challenges will be key to including pharmacists in testing and treatment of priority diseases. Sociopolitical considerations include migrating to flexible national legislation and scope of practices as well as engagement with other health care providers and the public to increase the acceptance of pharmacists participating in test and treat services. Resourcing issues include health care financing for test and treat services to parallel established systems or use voucher systems and service competition. In addition, pharmacists can use their training in supply chain management to ease and prevent medication stockouts in test to treat initiatives. Investments in technologies that support disease surveillance, basic reporting, and interoperability with health management information systems can integrate these initiatives into health care systems. Competency considerations comprise test and treat specific education for the pharmacy profession to equip them with the knowledge and confidence to execute successfully. Monitoring and evaluating the outcomes of these services can facilitate the scalability of test and treat initiatives. Pharmacists are uniquely positioned to bring testing and treatment from the clinic to the community.

BACKGROUND: The Centers for Disease Control and Prevention led an investigation to determine if Strongyloides infection in a right kidney recipient was an existing chronic infection, or if the infection was transmitted from an infected organ donor. METHODS: Evidence regarding the organ donor and organ recipients Strongyloides testing, treatment, and risk factors were gathered and evaluated. The case classification algorithm created by the Disease Transmission Advisory Committee was utilized. RESULTS: The organ donor had risk factors for Strongyloides infection; the banked donor specimen, submitted for serology testing 112 days post-donor death, was positive. The right kidney recipient was negative for Strongyloides infection pretransplant. Strongyloides infection was diagnosed via small bowel and stomach biopsies. The left kidney recipient had risk factors for Strongyloides infection. Two posttransplant Strongyloides antibody tests were negative at 59 and 116 days posttransplant; repeat antibody tests returned positive at 158 and 190 days posttransplant. Examination of bronchial alveolar lavage fluid collected 110 days posttransplant from the heart recipient showed a parasite morphologically consistent with Strongyloides species. She subsequently developed complications from Strongyloides infection, including hyperinfection syndrome and disseminated strongyloidiasis. Based on the evidence from our investigation, donor-derived strongyloidiasis was suspected in one recipient and proven in two recipients. CONCLUSION: The results of this investigation support the importance of preventing donor-derived Strongyloides infections by laboratory-based serology testing of solid organ donors. Donor positive testing results would direct the monitoring and treatment of recipients to avoid severe complications.

The pharmacy profession plays a vital role in sustaining and advancing population health. Pharmacists’ unique knowledge of the medication use system is crucial in the development and implementation of public health prevention strategies and interventions. These include dispensing medications and administering vaccines, developing clinical treatment guidelines for both infectious and chronic diseases, and educating the public on pharmaceuticals and health-related topics.1 Many pharmacists may not be aware of opportunities to become involved with public health initiatives or are sometimes overlooked as potential collaborators. One distinguished avenue for pharmacists to enter public health is through the Epidemic Intelligence Service (EIS) at the U.S. Centers for Disease Control and Prevention (CDC).

We evaluated the performance of self-collected anterior nasal swab (ANS) and saliva samples compared with healthcare worker-collected nasopharyngeal swab specimens used to test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We used the same PCR diagnostic panel to test all self-collected and healthcare worker-collected samples from participants at a public hospital in Atlanta, Georgia, USA. Among 1,076 participants, 51.9% were men, 57.1% were >50 years of age, 81.2% were Black (non-Hispanic), and 74.9% reported >1 chronic medical condition. In total, 8.0% tested positive for SARS-CoV-2. Compared with nasopharyngeal swab samples, ANS samples had a sensitivity of 59% and saliva samples a sensitivity of 68%. Among participants tested 3-7 days after symptom onset, ANS samples had a sensitivity of 80% and saliva samples a sensitivity of 85%. Sensitivity varied by specimen type and patient characteristics. These findings can help physicians interpret PCR results for SARS-CoV-2.

Poller et al., in this Journal, provided a useful consensus for use of personal protective equipment for managing high consequence infectious disease1. Although this was driven largely by recent Ebola virus disease emergencies, we should remind your readers of the continuing problem of Lassa fever (LF) in West Africa. LF is a febrile infectious disease caused by Lassa virus. The clinical presentation of the disease is nonspecific and includes fever, fatigue, hemorrhage, gastrointestinal symptoms, respiratory symptoms, and neurological symptoms2. The observed case fatality rate among patients hospitalized with severe LF is 15–20%3,4. The disease is mainly spread to humans through contamination with the urine or faeces of infected rats2. Human-to-human transmission can occur through contact with the body fluids of infected persons. Therefore, health care workers are at high risk for infection when the standard precautions for infection prevention and control including appropriate personal protective equipment are inadequate5.

BACKGROUND: In September, 2017, human monkeypox re-emerged in Nigeria, 39 years after the last reported case. We aimed to describe the clinical and epidemiological features of the 2017-18 human monkeypox outbreak in Nigeria. METHODS: We reviewed the epidemiological and clinical characteristics of cases of human monkeypox that occurred between Sept 22, 2017, and Sept 16, 2018. Data were collected with a standardised case investigation form, with a case definition of human monkeypox that was based on previously established guidelines. Diagnosis was confirmed by viral identification with real-time PCR and by detection of positive anti-orthopoxvirus IgM antibodies. Whole-genome sequencing was done for seven cases. Haplotype analysis results, genetic distance data, and epidemiological data were used to infer a likely series of events for potential human-to-human transmission of the west African clade of monkeypox virus. FINDINGS: 122 confirmed or probable cases of human monkeypox were recorded in 17 states, including seven deaths (case fatality rate 6%). People infected with monkeypox virus were aged between 2 days and 50 years (median 29 years [IQR 14]), and 84 (69%) were male. All 122 patients had vesiculopustular rash, and fever, pruritus, headache, and lymphadenopathy were also common. The rash affected all parts of the body, with the face being most affected. The distribution of cases and contacts suggested both primary zoonotic and secondary human-to-human transmission. Two cases of health-care-associated infection were recorded. Genomic analysis suggested multiple introductions of the virus and a single introduction along with human-to-human transmission in a prison facility. INTERPRETATION: This study describes the largest documented human outbreak of the west African clade of the monkeypox virus. Our results suggest endemicity of monkeypox virus in Nigeria, with some evidence of human-to-human transmission. Further studies are necessary to explore animal reservoirs and risk factors for transmission of the virus in Nigeria. FUNDING: None.
