Among them, 17 (51.51%) were published after 2014, when the WHO first identified CCHF as a global health threat [ 20 ].…”

“…Due to the reduced number of available estimates, rangers and hunters were collapsed into a single group that included 8 estimates (range 2 to 72) for a total of 328 samples [ 25 , 40 , 41 , 43 , 45 , 46 , 50 , 61 ]. Moreover, 12 studies provided estimates for the general population of the assessed areas [ 42 , 43 , 46 , 47 , 49 , 50 , 51 , 53 , 55 , 61 , 62 ], whose size ranged between 19 to 1677 samples.…”

“…Regarding rangers and hunters, a total of 13 positive cases out of 328 samples were identified, with a crude prevalence of 3.39%. However, more than half of the reported cases were included in the single report from Myanmar (prevalence of 10.77%) [ 61 ]. The remaining individual estimates encompassed three negative reports [ 43 , 45 , 52 ], three reports ranging between 3.13% [ 41 ], 3.45% [ 40 ], and 4.17% [ 25 ], as well as an outlier represented by the study of Arteaga et al [ 50 ], which only included two cases, one of which was IgG-positive for CCHFV (50.00%).…”

Crimean Congo Hemorrhagic Fever (CCHF) Virus can cause a serious human disease, with the case fatality ratio previously estimated to be 30–40%. Our study summarized seroprevalence data from occupational settings, focusing on the following occupational groups: animal handlers, abattoir workers, farmers, healthcare workers, veterinarians, rangers, and hunters. Systematic research was performed on three databases (PubMed, EMBASE, MedRxiv), and all studies reporting seroprevalence rates (IgG-positive status) for CCHF virus were retrieved and their results were reported, summarized, and compared. We identified a total of 33 articles, including a total of 20,195 samples, i.e., 13,197 workers from index occupational groups and 6998 individuals from the general population. Pooled seroprevalence rates ranged from 4.751% (95% confidence intervals (95% CI) 1.834 to 11.702) among animal handlers, to 3.403% (95% CI 2.44 to 3.932) for farmers, 2.737% (95% CI 0.896 to 8.054) among rangers and hunters, 1.900% (95% CI 0.738 to 4.808) for abattoir workers, and 0.644% (95% CI 0.223–1.849) for healthcare workers, with the lowest estimate found in veterinarians (0.283%, 95% CI 0.040–1.977). Seroprevalence rates for abattoir workers (odds ratio (OR) 4.198, 95% CI 1.060–16.464), animal handlers (OR 2.399, 95% CI 1.318–4.369), and farmers (OR 2.280, 95% CI 1.419 to 3.662) largely exceeded the official notification rates for CCHF in the general population. CCHF is reasonably underreported, and pooled estimates stress the importance of improving the adherence to personal protective equipment use and appropriate preventive habits.

“…Major harvesting systems and extractive industries, such as mining, logging, fishing, and aquaculture, have been associated with disease emergence (e.g. Ebola virus disease, Marburg' s virus; Crimean-Congo Haemorrhagic Fever Virus; (Chai, Darwin Murrell & Lymbery, 2005;Towner et al, 2006;Swanepoel et al, 2007;Olivero et al, 2017;Evans et al, 2021). We do not discuss these in detail under wildlife trade because of their mostly indirect associations with such drivers as landscape change and human intrusion rather than trade itself.…”

Situation analysis on the roles and risks of wildlife in the emergence of human infectious diseases

This situation analysis presents a thorough, evidence-based examination of the relationship between wildlife and zoonosis, wildlife and emerging human pathogens and associated diseases, their origins, drivers, and risk factors. There is considerable divergence of opinion around the subject both within and outside the biodiversity conservation community and given the ontological challenges and highly different perspectives, contradictory narrative is unsurprising. Context is all-important and to clarify this in the analysis, the evidence of human diseases coming from wildlife is compared to diseases emerging from domestic animals and humans themselves, to provide context and proportions of the relative risk. The report highlights key knowledge, and provides perspective on where research, policy, interventions, and capacity building are needed to reduce risks of zoonoses and emergent animal-origin human diseases globally.
