Zoonotic Disease Risk Assessment and Monitoring

Emerging diseases of zoonotic origin such as COVID-19 are a continuing public health threat in China that lead to a significant socioeconomic burden. This study reviewed the current laws and regulations, government reports and policy documents, and existing literature on zoonotic disease preparedness and prevention across the forestry, agriculture, and public health authorities in China, to articulate the current landscape of potential risks, existing mandates, and gaps. A total of 55 known zoonotic diseases (59 pathogens) are routinely monitored under a multi-sectoral system among humans and domestic and wild animals in China. These diseases have been detected in wild mammals, birds, reptiles, amphibians, and fish or other aquatic animals, the majority of which are transmitted between humans and animals via direct or indirect contact and vectors. However, this current monitoring system covers a limited scope of disease threats and animal host species, warranting expanded review for sources of disease and pathogen with zoonotic potential. In addition, the governance of wild animal protection and utilization and limited knowledge about wild animal trade value chains present challenges for zoonotic disease risk assessment and monitoring, and affect the completeness of mandates and enforcement. A coordinated and collaborative mechanism among different departments is required for the effective monitoring and management of disease emergence and transmission risks in the animal value chains. Moreover, pathogen surveillance among wild animal hosts and human populations outside of the routine monitoring system will fill the data gaps and improve our understanding of future emerging zoonotic threats to achieve disease prevention. The findings and recommendations will advance One Health collaboration across government and non-government stakeholders to optimize monitoring and surveillance, risk management, and emergency responses to known and novel zoonotic threats, and support COVID-19 recovery efforts.

Veterinary practices or activities expose professionals to occupational hazards, including infection with zoonotic diseases, during contact with animals. To assess animal care professionals' practice towards zoonotic disease management and infection control practices (ICPs) in selected areas of the Wolaita zone, a cross-sectional survey was conducted using a structured questionnaire survey. A total of 287 animal care professionals were registered by the Wolaita zone livestock and fishery office and working in nine different districts of the Wolaita zone. Of these, 135 animal care professionals working across nine different districts of the Wolaita zone were interviewed in the current study. The survey showed that about 55% (74/135) of respondents were animal health assistants, and about 84% (114/135) of the professionals were males. In terms of utilization of ICP, about 72% of professionals routinely wash their hands before eating and drinking in their workplace. However, approximately 7% of professionals sometimes eat or drink at the workplace. Additionally, almost 32% of the professionals always wash their hands between patient contacts. In the survey, approximately 49% of veterinarians said they sterilized and reused disposable needles. When dealing with an animal suspected of carrying a zoonotic infection, nearly 25% of experts isolate or quarantine diseased animals, and only about 25% of the experts remove their personal protective equipment (PPE) before interacting with other animals. Approximately 62% of responders said they used outwear (PPE) when carrying out surgery and 28% when performing a necropsy. Nearly 39% of veterinarians reported using gloves and gowns when assisting with parturition or handling conception products, and around 36% of practitioners utilized proper PPE when handling blood samples. Our findings show that the veterinary community in the Wolaita Zone's selected sites needs to be educated about ICPs regularly. A better understanding of the risk of zoonotic disease exposure, as well as alternatives for reducing this risk and liability problems, may encourage the use of infection control measures. Successful partnerships across multiple professional sectors should use a One Health approach that includes stakeholders from the human, animal, and environmental categories.
