What the literature leaves open

  • Experimental validation of the results is needed. Further investigation of the antiviral potential of the identified compounds is required. The study of other potential inhibitors of CCHFV replication is necessary.

    Assessment of FDA-Approved Antiviral Drugs Indicated for Different Viral Infections Against Crimean-Congo Hemorrhagic Fever Virus: Molecular Docking and Molecular Dynamics Simulations · 2026 · DOI

  • Our analytical results demonstrate that with high β2 (animal-to-animal transmission), tick control alone is insufficient—a finding that could not emerge from simulation alone without systematic sensitivity analysis.

    Modeling Tick-Borne Zoonoses with Multi-Host and Multi-Vector Transmission Dynamics · 2026 · DOI

  • Further research is needed to monitor the potential northward expansion of CCHFV. Studies should investigate the ecological and environmental factors driving the expansion of Hyalomma spp. Research should focus on the development of effective surveillance and control measures for CCHFV.

    Equine sentinels and one health: a comprehensive serological survey of Crimean-Congo hemorrhagic fever virus in southeastern and Central Europe · 2026 · DOI

  • This prediction suggests further research is needed to see if the identified SNP affects IFITM3 protein expression. The absence of in vitro or in vivo functional analyses remains a limitation of this study. While the IFITM3 gene could be a significant candidate for SFTSV infection, no studies have examined genetic variation in raccoon dogs, a potential host for direct transmission of SFTS to humans.

    First Report of IFITM3 Polymorphism Associated with Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) Infection in the Raccoon Dog · 2026 · DOI

  • There is a lack of understanding about the risk of human-to-human transmission of hantavirus. There is no licensed treatment or vaccine available for hantavirus.

    Hantavirus: What you need to know · 2026 · DOI

  • The risk of person-to-person transmission of the Andes strain is not fully understood. The effectiveness of current measures to minimize transmission is not known.

    Hantavirus: French and US nationals test positive as cruise ship docks in Canary Islands: Video 1 · 2026 · DOI

  • Yet control efforts remain largely confined to individual-level tick bite prevention, reflecting persistent gaps in understanding the ecological mechanisms that sustain SFTS transmission, particularly how environmental factors shape transmission dynamics across vectors, animal reservoirs, and human populations.

    Systematic review of environmental factors associated with severe fever with thrombocytopenia syndrome occurrences in humans · 2026 · DOI

  • It highlights the need for more research on the environmental and occupational factors associated with the transmission of the virus.

  • Further experimental validation of Octavir-1Q is needed. In-vivo experiments and clinical trials are required to fully evaluate the potential of Octavir-1Q. The study suggests that further research on the pharmacokinetic properties of Octavir-1Q is needed.

    IN-SILICO VALIDATION OF A QUADRUPLE-TARGET INHIBITION STRATEGY FOR ORTHOHANTAVIRUS USING LEAD COMPOUND OCTAVIR-1Q · 2026 · DOI

  • The lack of awareness and vigilance in Guatemala and Central America is a challenge. The presence of wild rodents and the potential for hantavirus transmission is a challenge. The need for community prevention measures is a challenge.

    Hantavirus: ¿Qué riesgos hay para Guatemala y Centroamérica? · 2026 · DOI

  • The absence of reports does not necessarily imply the absence of viral circulation. There is a need for increased vigilance and community prevention measures in Guatemala and Central America.

    Hantavirus: ¿Qué riesgos hay para Guatemala y Centroamérica? · 2026 · DOI

  • Antibiotic misuse and diagnostic uncertainty in resource-limited settings. Limited availability of advanced laboratories in outbreak-prone regions. Need for systematic parasitic and bacterial confirmation to refine specificity estimates.

    Evaluating myxovirus resistance protein A-based rapid testing combined with pathogen sequencing for arboviral and incidental viral infection surveillance in Senegal · 2026 · DOI

  • Future research should focus on improving surveillance and control measures to prevent zoonotic spillover. The study suggests that routine genomic monitoring is necessary to track the evolution of CCHFV. Further research is needed to understand the epidemiology of CCHFV in Nigeria.

    A comprehensive review of the epidemiology and research gaps of Crimean-Congo Haemorrhagic Fever in Nigeria · 2026 · DOI

  • The lack of dedicated tick surveillance is a major research gap. The weak integration of CCHFV into priority zoonotic disease frameworks is another research gap. The extremely low national research output is also a significant research gap.

    A comprehensive review of the epidemiology and research gaps of Crimean-Congo Haemorrhagic Fever in Nigeria · 2026 · DOI

  • Macrobrachium rosenbergii nodavirus (MrNV) is the associated helper virus of XSV and their co-infection has been linked to white tail disease in freshwater prawns globally, although the role of XSV is remains unclear.

    Hidden diversity and expanded host range of sarthroviruses, including terrestrial vertebrates · 2026 · DOI

  • Potential need for intensive respiratory support. Limited awareness and understanding of hantavirus infections among radiologists and emergency medicine professionals.

    Hantavirus infection in emergency radiology: Imaging manifestations, pathophysiology, and infection control considerations · 2026 · DOI

  • The paper does not provide a comprehensive review of all imaging modalities. The discussion of infection control considerations is limited to general recommendations.

    Hantavirus infection in emergency radiology: Imaging manifestations, pathophysiology, and infection control considerations · 2026 · DOI

  • The study is based on in-silico results and may require further experimental validation. The study does not report any clinical trials or in-vivo experiments. The study focuses on a single lead compound, Octavir-1Q.

    IN-SILICO VALIDATION OF A QUADRUPLE-TARGET INHIBITION STRATEGY FOR ORTHOHANTAVIRUS USING LEAD COMPOUND OCTAVIR-1Q · 2026 · DOI

  • The fragility of local healthcare capacity and propagation by conflict, community distrust and population mobility have contributed to the outbreak.

    Bundibugyo virus outbreak: when a concerning pathogen meets a humanitarian emergency · 2026 · DOI

  • The study identifies a gap in the understanding of the current distribution of CCHF in equids across Southeastern and Central Europe. The expansion of Hyalomma spp. poses a new and growing public health concern in Central and Western Europe.
