COVID-19 in pastoral contexts in the greater Horn of Africa: Implications and recommendations.

COVID-19 is a global pandemic that continues to spread around the world, including to Africa where cases are steadily increasing. The African Centres for Disease Control and Prevention is leading the pandemic response in Africa, with direction from the World Health Organization guidelines for critical preparedness, readiness, and response actions. These are written for national governments, lacking nuance for population and local differences. In the greater Horn of Africa, conditions unique to pastoralists such as inherent mobility and limited health and service infrastructure will influence the dynamics of COVID-19. In this paper, we present a One Health approach to the pandemic, consisting of interdisciplinary and intersectoral collaboration focused on the determinants of health and health outcomes amongst pastoralists. Our contextualized public health strategy includes community One Health teams and suggestions for where to implement targeted public health measures. We also analyse the interaction of COVID-19 impacts, including those caused directly by the disease and those that result from control efforts, with ongoing shocks and vulnerabilities in the region (e.g. desert locusts, livestock disease outbreaks, floods, conflict, and development displacement). We give recommendations on how to prepare for and respond to the COVID-19 pandemic and its secondary impacts on pastoral areas. Given that the full impact of COVID-19 on pastoral areas is unknown currently, our health recommendations focus on disease prevention and understanding disease epidemiology. We emphasize targeting pastoral toponymies with public health measures to secure market access and mobility while combating the direct health impacts of COVID-19. A contextualized approach for the COVID-19 public health response in pastoral areas in the Greater Horn of Africa, including how the pandemic will interact with existing shocks and vulnerabilities, is required for an effective response, while protecting pastoral livelihoods and food, income, and nutrition security.

Experiences in participatory surveillance and community-based reporting systems for H5N1 highly pathogenic avian influenza: a case study approach.

Participatory surveillance (PS) is the application of participatory rural appraisal methods to the collection of epidemiological information to inform decision-making and action. It was applied in Africa and Asia as part of emergency programs to address the H5N1 highly pathogenic avian influenza (HPAI) pandemic. The approach resulted in markedly increased case detection in countries experiencing HPAI, and a better understanding of the epidemiological situation. Where HPAI was absent and PS was implemented, the method did not result in false positives and contributed to the overall epidemiological assessment that the country was free of disease. It was noted that clarity of surveillance objectives and resulting data needs at the outset was essential to optimize the balance of surveillance methods, size of the program and costs. The quality of training programs and adherence to international guidelines on good PS training practice were important for assuring the competence of PS practitioners. Orientation of senior decision-makers was an important step in assuring effective program management and appropriate use of results. As a problem-solving methodology, PS is best used to rapidly assess situations and inform strategy. Several countries continued PS after the end of projects and went on to apply PS to other health challenges.

Epidemiological assessment of the Rift Valley fever outbreak in Kenya and Tanzania in 2006 and 2007.

To capture lessons from the 2007 Rift Valley fever (RVF) outbreak, epidemiological studies were carried out in Kenya and Tanzania. Somali pastoralists proved to be adept at recognizing symptoms of RVF and risk factors such as heavy rainfall and mosquito swarms. Sandik, which means "bloody nose," was used by Somalis to denote disease consistent with RVF. Somalis reported that sandik was previously seen in 1997/98, the period of the last RVF epidemic. Pastoralists communicated valuable epidemiological information for surveillance and early warning systems that was observed before international warnings. The results indicate that an all or none approach to decision making contributed to the delay in response. In the future, a phased approach balancing actions against increasing risk of an outbreak would be more effective. Given the time required to mobilize large vaccine stocks, emergency vaccination did not contribute to the mitigation of explosive outbreaks of RVF.

Internationalizing veterinary education in the 21st century.

This paper presents the results of a survey conducted in the spring of 2001 to assess international activities at colleges of veterinary medicine in North America. A questionnaire was sent to all 31 colleges of veterinary medicine in the United States and Canada, of which 22 responded. Of those schools responding to the survey, 86% have International Veterinary Medicine (IVM) programs and most have faculty involved in internationally oriented research (95%), in teaching IVM (74%), in mentoring veterinary students in IVM (84%), and in international consultancies (84%). Funding sources for faculty international activities include foundations, intramural funds, curriculum development grants, endowment/development funds, and sabbaticals. Foreign animal diseases are the most commonly taught international topic. The increasing importance of international veterinary issues is leading to the internationalization of the veterinary education in North America. Most IVM programs include activities of both faculty and students. Greater collaboration between faculty and programs across schools would allow schools to benefit from each other's strengths in IVM education.
