A survey amongst sheep and goat producers and veterinarians was undertaken to collect epidemiological data on orf in South Africa. Previous epidemiological studies on the presence of the disease in the country have not been documented and this report is the first descriptive epidemiological study of orf in South Africa. A seven-month investigation, realised by direct and indirect interviews...

markable. Laboratory evaluations were significant for a leukocyte count of 1,500/mm (normal value, 4,500–11,000/mm) and macrocytic anemia (hematocrit, 30%; hemoglobin level, 9.8 g/dL; mean corpuscular volume, 104.6 fL). The absolute neutrophil and lymphocyte counts were 870 and 600/mm, respectively. The blood urea nitrogen level was 34 mg/dL (normal value, 7–22 mg/dL), and the creatinine level ...

AIM The objective of this study was to screen the prevalence of contagious ecthyma (CE) among the goat population of Assam owing to its high prevalence rate. MATERIALS AND METHODS In this study, a total of 231 serum samples were collected from 12 districts of Assam during September 2013 to July 2014. The serum samples were tested for the presence of antibodies against Orf virus (ORFV) by indi...

Orf virus is a parapoxvirus that causes recurring contagious ecthyma or orf disease in goat, sheep and other wild and domestic ruminants. Infected animals show signs of pustular lesions on the mouth and muzzle and develop scabs over the lesions. Although the infection is usually cleared within 1-2 months, delayed growth and associated secondary infections could still impact the herds. Orf virus...

This paper proposes a test for the existence and the degree of contagious presenteeism and negative externalities in sickness insurance schemes. First, we theoretically decompose moral hazard into shirking and contagious presenteeism behavior. Then we derive testable conditions for reduced shirking, increased presenteeism, and the level of overall moral hazard when benefits are cut. We implemen...

With rapidly increasing herd sizes, focus on contagious udder pathogens becomes important. Based on a yearly test of bulk tank milk in Danish dairy herds, the prevalence of herds infected with Streptococcus agalactiae (S. agalactiae) increased from 2 % in 2000 to 7 % in 2010, while approximately 90 % of the herds were positive for Staphylococcus aureus (S. aureus) (Katholm, et al., 2012). The r...

The Orf disease, also known as contagious ecthyma, is a zoonotic infection caused by a dermatotropic parapoxvirus that commonly infects small ruminants such as sheep and goats. It is transmitted to humans through contact with an infected animal or fomites. Human infection typically is associated with occupational animal contact. We recently treated a healthy 41-year-old woman who presented a ha...

Orf, also known as ecthyma contagiosum or contagious pustular dermatitis, is a viral zoonotic disease resulting from the direct or indirect contact of damaged skin with infected animals. The causative microorganism is the orf virus, an epitheliotropic DNA virus from the Parapoxvirus group, which generally infects sheep, goats, and various other domestic and wild ovine animals. A male patient pr...
