BACKGROUND: Mpox, primarily endemic to Central and West Africa, has seen a concerning global rise in recent years. There is a critical need to synthesize evidence on successful strategies that have been used to contain and respond to mpox globally to inform policy and best practices. METHODS: A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Four databases were searched for publications between 2017 to August 2024. Articles were included if they reported on mpox response and containment strategies. RESULTS: A total of 72 studies were included in this systematic review. During mpox outbreaks, screening was primarily conducted at sexual health clinics, including Sexually Transmitted Infections and PrEP (Pre-exposure prophylaxis) clinics. PCR (Polymerase chain reaction) testing was the most commonly reported diagnostic method. Three treatment options were identified: Tecovirimat, Vaccinia Immune Globulin, and Cidofovir. Additionally, vaccines were classified into two main categories: (i) JYNNEOS (also known as MVA-BN and IMVANEX) and (ii) ACAM2000. Studies highlighted several challenges associated with isolation measures, including difficulties in maintaining consistent follow-up, ensuring patient compliance, and managing large-scale isolation logistics. Surveillance strategies emphasized effective data collection, case investigations, and public health coordination to strengthen outbreak response. Pre-emergency preparedness efforts focused on international collaboration, the development of distribution networks, models of care for Mpox treatment, and the analysis of past outbreaks to improve future response strategies. CONCLUSION: This review synthesized strategies for mpox outbreak response and containment, highlighting the need to expand vaccine access beyond GBMSM/LGBTQIA + populations, integrate screening into routine sexual health services, adopt alternative delivery and diagnostic approaches, strengthen surveillance and pre-emergency preparedness, and promote context-specific research in low- and middle-income countries to inform evidence-based policy and practice.

BackgroundThe mpox outbreak in 2022 posed a new challenge to the medical system. We aimed to study the impact of human immunodeficiency virus (HIV) coinfection on mpox patients.MethodsThis study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.ResultsOur study included 27 articles for meta-analysis and divided mpox patients into two groups: one group was HIV-positive, and the other group was HIV-negative. We found that the age of HIV-positive patients was significantly greater than that of HIV-negative patients (SMD = 0.35, 95% CI: 0.29-0.41) and that there were more men who had sex with men in the HIV-positive group (OR = 3.98, 95% CI: 3.04-5.21). Syphilis (OR = 2.66, 95% CI: 2.13-3.33), hepatitis B (OR = 3.94, 95% CI: 2.93-5.30), hepatitis C (OR = 5.71, 95% CI: 3.06-10.64), proctitis (OR = 1.52, 95% CI: 1.17-1.98), fever (OR = 1.15, 95% CI: 1.01-1.30), diarrhea (OR = 1.69, 95% CI: 1.03-2.77) and pustules (OR = 1.33, 95% CI: 1.08-1.62) were more common among HIV-positive patients. HIV coinfection seemed to be associated with a decrease in the CD4+ T-cell count (SMD = -0.78, 95% CI: -1.34 to -0.23) and hemoglobin (SMD = -0.43, 95% CI: -0.64 to -0.22) and albumin (SMD = -0.35, 95% CI: -0.55 to -0.15) levels, whereas the CD8+ T-cell count yielded the opposite statistical conclusion (SMD = 0.35, 95% CI: 0.03-0.67). We also found that HIV-positive patients had more hospitalizations (OR = 1.63, 95% CI: 1.22-2.19), more severe mpox (OR = 1.82, 95% CI: 1.28-2.58), more need for tecovirimat treatment (OR = 4.25, 95% CI: 1.59-11.4), and higher mortality (OR = 3.36, 95% CI: 1.15-9.83).ConclusionOverall, HIV coinfection may influence the disease process and clinical indicators of mpox patients and is associated with more severe clinical outcomes.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420251056729, PROSPERO registration number: CRD420251056729.

Tecovirimat was approved by the FDA in July 2018 as the first drug ever approved to treat smallpox.[L3626][L3614] Tecovirimat was later approved by Health Canada in December 2021,[L39397] followed by the approval from the European Commission in January 2022.[L40159] Other than smallpox, tecovirimat is also indicated to treat complications due to replication of the vaccinia virus following vaccination against smallpox, and to treat monkeypox and cowpox in adults and children.[L40154] Tecovirimat is available as both oral and intravenous formulations.[L41835]

There is no clinical experience with overdosage of tecovirimat. In case of overdosage, patients should be monitored for any signs or symptoms of adverse effects. Hemodialysis is not expected to effectively remove tecovirimat in overdosed patients.
[L41835]
The P37 protein is encoded by a highly conserved gene in all members of the orthopoxvirus genus.[L41835] P37 interacts with the Rab9 GTPase and TIP47, which are components of late endosome-derived transport vesicles. Interaction of P37 and Rab9 GTPase and TIP47 leads to the formation of the virus-specific wrapping complex for enveloped virions.[A35133] Tecovirimat is an inhibitor of P37: it blocks the interaction of P37 with Rab9 and TIP47, preventing the formation of the wrapping complex.[A35131][A35133][L40154][L41835]
How the body processes this drug — absorption, distribution, metabolism, and elimination
[A35133]
Following oral administration of 600 mg tecovirimat in healthy adults, the mean steady-state AUC0-24hr was 29816 hr x ng/mL and the Cmax was 2159 ng/mL. Following intravenous administration of 200 mg tecovirimat every 12 hours, the mean steady-state AUC0-24hr was 39405 hr x ng/mL and the Cmax was 2630 ng/mL. The Tmax is about six hours.
[L41835]
The steady-state is achieved within four to six days.
[A35134][L41835]
The oral bioavailability of tecovirimat is increased when taken with food.
A moderate fat and calories meal increased the drug exposure (AUC) by 39% when tecovirimat was orally administered in conjunction with food.

Major metabolites are metabolites M4 (N-{3,5-dioxo-4-azatetracyclo[5.3.2.0{2,6}.0{8,10}]dodec-11-en-4-yl}amine), M5 (3,5-dioxo-4-aminotetracyclo[5.3.2.0{2,6}.0{8,10}]dodec-11-ene), and TFMBA (4 (trifluoromethyl) benzoic acid). None of the metabolites is pharmacologically active. None of the glucuronide conjugates was found as a major metabolite in plasma.
[L40154]
The exact chemical structures of tecovirimat metabolites have not been fully characterized.
[L41835][L40154]
In urine, primary tecovirimat glucuronide conjugate and M4 glucuronide conjugate were the most abundant components accounting for means of 24.4% and 30.3% of dose, respectively.
