Human norovirus (HuNoV) causes widespread foodborne illness and is hard to study. New food processing, vaccines, and antiviral strategies are urgently needed to control this contagious pathogen.
Area of Science:
- Food Virology
- Infectious Diseases
- Public Health
Background:
- Human norovirus (HuNoV) is a major cause of global foodborne disease outbreaks.
- HuNoV is highly stable, contagious, and requires few particles to cause illness.
- Studying HuNoV is challenging due to the absence of efficient in vitro culture systems and animal models.
Purpose of the Study:
- To highlight the urgent need for effective control measures against Human norovirus.
- To emphasize the necessity for developing novel food-processing technologies for HuNoV inactivation.
- To advocate for advancements in vaccine development and antiviral strategies targeting HuNoV.
Main Methods:
- Review of current knowledge on HuNoV biology, transmission, and control challenges.
- Analysis of surrogate models (e.g., VLP, MNV, FCV) used in HuNoV research.
- Evaluation of existing and potential intervention strategies, including food processing, vaccines, and antivirals.
Main Results:
- Limited understanding of HuNoV biology due to research model limitations.
- Identification of high-risk foods (seafood, fresh produce, ready-to-eat) for HuNoV contamination.
- Current lack of effective control measures for HuNoV outbreaks.
Conclusions:
- Urgent need for innovative food-processing technologies to inactivate HuNoV in contaminated foods.
- Consideration of diverse vaccine candidates, including live vectored vaccines, alongside VLP-based vaccines.
- Exploration of virus-receptor interaction blockage as a potential antiviral target.
- Call for integrated, multidisciplinary research and enhanced food virology education programs.
