Diagnostic assays that can simultaneously determine the presence of infection with multiple pathogens are key for diagnosis and surveillance. Current multiplex diagnostic assays are complex and often have limited availability. We developed a simple, multianalyte, pathogen detection assay for screening and serosurveillance using the Luminex Magpix platform that is high throughput and can be helpful in monitoring multiple diseases. The Luminex bead-based 10-plex immunoassay for the detection of HIV-1, HIV-2, Treponema pallidum, hepatitis B virus (HBV), hepatitis C virus (HCV), herpes simplex virus 1 (HSV-1), and HSV-2 infections was accomplished by coupling beads with specific antigens to detect IgG antibodies in plasma or serum samples. Each coupled antigen was systematically optimized, and the performance was evaluated using a panel of well-characterized specimens (

Illegal animal trade (pet, wildlife, animal products, etc.) is an example of transnational organized crime (T.O.C.) that generates a large business with huge profit margins. This criminal activity causes several negative effects on human health (zoonoses), animal health and welfare, market protection, consumer fraud and may be used as tool of agro/bio-terrorism. Illegal animal trade can facilitate the spread of zoonoses that are defined as diseases and infections that are transmitted by vertebrate animals to man. Humans are affected by more than 1,700 known pathogens: 60% of existing human infectious diseases are zoonotic and at least 75% of emerging infectious diseases of humans have an animal origin and 72% of zoonoses originate from wildlife or exotic animals. The Bio-Crime Project was developed in 2017 by Friuli Venezia Giulia Region (Italy) and Land Carinthia (Austria) together with other public institutions to combat illegal animal trade and to reduce the risk of disease transmission from animals to humans. Project partners agreed that a multi-agency approach was required to tackle the illegal animal trade that was high value, easy to undertake and transnational crime. The Bio-crime model of cross-border cooperation introduces the novel approach of replicating the cooperative framework given by the triad of Veterinary Public Health, Justice and Law Enforcements/Customs across borders using the International Police and Custom Cooperation Centres (IPCCCs) as a connection link among public entities of the neighbor countries. This model has been recognized as a best practice at European level because it can be easily replicated and scaled up without any supplementary cost for Member States.

Monkeypox virus and varicellazoster virus (VZV) cause visually similar rash illnesses. Monkeypox is more virulent, with fatality rates up to 10%. In June 2007, reports were received of a rash illness outbreak in isolated villages in Likouala district, Republic of the Congo. Blood specimens were obtained from 142 individuals reporting rash illness between January and September 2007 from four villages in Likouala. Thirty-seven cases of probable VZV were identified based on low VZV IgG avidity; cases occurred in all four villages. No probable monkeypox cases with orthopoxvirus-positive IgM responses were observed; however, three possible monkeypox cases, in individuals26 years of age, with rash illness occurring56 days before sampling and positive orthopoxvirus-specific IgG responses, were identified. Remoteness and delays in reporting limited collection of acute diagnostic specimens. Improvements in rash illness surveillance and infection control, through training of health workers and timely acquisition of diagnostic specimens, are being undertaken.

Monkeypox virus is a zoonotic orthopoxvirus (OPX) of west and central sub-Saharan Africa. We conducted a cross-sectional serosurvey in Likouala region, Republic of Congo to assess exposure to OPX. Whole blood was collected using Nobuto blood filter strips (NBFS). Titers of IgM and IgG to OPX were assessed using an enzyme-linked immunosorbent assay. Demographic and clinical characteristics were compared with serostatus using the chi-square test or Fisher's exact test. Multivariate logistic regression was performed to evaluate factors for independent association with serostatus. A total of 994 specimens were analyzed; the overall seroprevalence for OPX IgM was 1.7%. Age25 years reduced the likelihood of OPX exposure, and persons living in Ngangania village had independently higher odds (odds ratio = 33.5, 95% confidence interval = 7.2-166). Blood collection for serosurveys using NBFS is feasible and practical. Adult activities such as hunting and carcass preparation may play an important role in exposure to Monkeypox virus.

This report describes the first reported outbreak of human monkeypox in the Republic of Congo. Eleven confirmed and probable monkeypox cases were observed during this outbreak, all were less than 18 years old, and most resided on the grounds of the Government Hospital in Impfondo. Molecular, virologic, and serologic, and diagnostic assays were used to detect evidence of monkeypox (or orthopox) virus infection in individuals with striking dermatologic and other clinical manifestations. The majority of cases in this outbreak experienced significant, symptomatic illnesses; there was one death, possibly involving secondary complications, and one instance of profound sequelae. Up to six sequential transmissions of monkeypox virus from person to person are hypothesized to have occurred, making this the longest uninterrupted chain of human monkeypox fully documented to date. The pattern of sustained human-to-human transmission observed during this outbreak may influence our current perception of the capacity for this zoonotic virus to adapt to humans.
