The increasing global emergence of zoonoses warrants improved awareness of activities that predispose vulnerable communities to greater risk of disease. Zoonotic disease outbreaks regularly occur within Myanmar and at its borders partly due to insufficient knowledge of behavioral risks, hindering participatory surveillance and reporting. This study employed a behavioral surveillance strategy among high-risk populations to understand the behavioral risks for zoonotic disease transmission in an effort to identify risk factors for pathogen spillover.

As part of a public health behavior change and communication strategy related to the identification of a novel ebolavirus in bats in Sierra Leone in 2016, a consortium of experts launched an effort to create a widely accessible resource for community awareness and education on reducing disease risk. The resulting picture book, , includes technical content developed by a consortium of experts in public health, animal health, conservation, bats, and disease ecology from 30 countries. The book has now been adapted, translated, and used in more than 20 countries in Africa and Asia.

Introduction: Antimicrobial resistance (AMR) is a growing global health threat for humans and animals. Environmental contamination of antimicrobials from human and domestic animal feces has been linked to AMR in wildlife populations, including rhesus macaques. This study aimed to describe the eco-epidemiology of AMR within and species isolated from rhesus macaques.

Article Synopsis
  • Scientists study how viruses and their animal hosts have changed together over time and how they can jump from animals to humans.
  • They used special models to see which newly found viruses from wildlife might be able to infect people, focusing on high-risk areas in Africa, Asia, and Latin America.
  • The research shows that new coronaviruses might infect more types of animals compared to other viruses, helping to figure out where to look for potential outbreaks in humans.

Article Synopsis
  • - The study examines the knowledge, attitudes, and practices (KAP) regarding zoonotic disease transmission among communities involved in wildlife trade in North Sulawesi, Indonesia, to help prevent future outbreaks.
  • - Researchers employed both qualitative (interviews and focus groups) and quantitative (questionnaires) methods, sampling 477 participants for surveys and collecting biological specimens from 254 individuals in targeted areas known for wildlife consumption.
  • - Findings revealed that while participants had some awareness of zoonotic diseases like rabies and bird flu, only 1% of the quantitative study group believed that contact with wild animals could lead to illness; biological tests found only one participant with evidence of a zoonotic infection.

Background: Interactions between humans and animals are the key elements of zoonotic spillover leading to zoonotic disease emergence. Research to understand the high-risk behaviors associated with disease transmission at the human-animal interface is limited, and few consider regional and local contexts.

Objective: This study employed an integrated behavioral-biological surveillance approach for the early detection of novel and known zoonotic viruses in potentially high-risk populations, in an effort to identify risk factors for spillover and to determine potential foci for risk-mitigation measures.

Anthropogenic land-use changes increase the frequency of interactions and habitat overlap between humans and macaques which play an important role in zoonotic disease transmission. This exploratory qualitative study aimed to examine connections between land-use change and macaque-human interactions and assess the chance of zoonotic disease transmission. We conducted ethnographic interviews and focus group discussions in Old Dhaka, Madaripur, and Chandpur, Bangladesh.

Article Synopsis
  • The USAID's PREDICT project is working to improve how we prevent and control diseases that can spread between animals and people.
  • They want to understand the risky behaviors of communities that live near animals and nature, to better detect and respond to potential diseases.
  • Researchers talked to people in high-risk jobs to learn what they think about the dangers of their work, finding that many don't see their activities as risky, which could make disease spread more likely.

Human interaction with animals has been implicated as a primary risk factor for several high impact zoonoses, including many bat-origin viral diseases. However the animal-to-human spillover events that lead to emerging diseases are rarely observed or clinically examined, and the link between specific interactions and spillover risk is poorly understood. To investigate this phenomenon, we conducted biological-behavioral surveillance among rural residents in Yunnan, Guangxi, and Guangdong districts of Southern China, where we have identified a number of SARS-related coronaviruses in bats.

Background: Strategies are urgently needed to mitigate the risk of zoonotic disease emergence in southern China, where pathogens with zoonotic potential are known to circulate in wild animal populations. However, the risk factors leading to emergence are poorly understood, which presents a challenge in developing appropriate mitigation strategies for local communities.

Methods: Residents in rural communities of Yunnan, Guangxi and Guangdong provinces were recruited and enrolled in this study.

Economically and politically disruptive disease outbreaks are a hallmark of the 21st century. Although pandemics are driven by human behaviours, current surveillance systems for identifying pandemic threats are largely reliant on the monitoring of disease outcomes in clinical settings. Standardized integrated biological-behavioural surveillance could, and should, be used in community settings to complement such clinical monitoring.

Simian immunodeficiency virus (SIV) infection of natural hosts is characterized by nonpathogenic chronic viremia, maintenance of gastrointestinal epithelial barrier integrity, and low numbers of target cells. Assessment of cell-associated virus load in T cell subsets in multiple anatomic compartments of chronically SIV-infected sabeus African green monkeys (AGMs) revealed that gastrointestinal memory CD4(+) T lymphocytes are a major source of cell-associated virus and a significant contributor to SIV viremia in AGMs.

Gecko adhesion is expected to be temperature insensitive over the range of temperatures typically experienced by geckos. Previous work is limited and equivocal on whether this expectation holds. We tested the temperature dependence of adhesion in Tokay and Day geckos and found that clinging ability at 12 degrees C was nearly double the clinging ability at 32 degrees C.
