[Zoonotic vaccinia in Colombia: Cumulative evidence of the emergence of poxviruses in the world].

The recent occurrence of vaccinia virus infections in humans and animals in Colombia, together with that reported for this and other species of the genus Orthopoxvirus in some South American, African, Asian and European countries, is supporting evidence of the emergence and re-emergence of the genus. This fact has become of great interest for public health around the world due to its biological and an epidemiological features, as was in the past the variola virus, one of its representatives. The emergence and re-emergence of the genus Orthopoxvirus may be a consequence of stopping vaccination against the variola virus in the 1970s and 1980s.

Progressive Vaccinia Acquired through Zoonotic Transmission in a Patient with HIV/AIDS, Colombia.

In March 2015, a patient in Colombia with HIV/AIDS was hospitalized for disseminated ulcers after milking cows that had vesicular lesions on their udders. Vaccinia virus was detected, and the case met criteria for progressive vaccinia acquired by zoonotic transmission. Adherence to an optimized antiretroviral regimen resulted in recovery.

Detection and Molecular Characterization of Zoonotic Poxviruses Circulating in the Amazon Region of Colombia, 2014.

During 2014, cutaneous lesions were reported in dairy cattle and farmworkers in the Amazon Region of western Colombia. Samples from 6 patients were analyzed by serologic and PCR testing, and results demonstrated the presence of vaccinia virus and pseudocowpox virus. These findings highlight the need for increased poxvirus surveillance in Colombia.

Human respiratory syncytial virus and metapneumovirus in patients with acute respiratory infection in Colombia, 2000 - 2011.

Objective: To describe the epidemiology of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) in Colombia from 2000 - 2011, including seasonal trends.

Methods: Nasopharyngeal aspirates and/or throat swabs from 14 870 patients with acute respiratory infections (ARI) were studied. Two subgroups were analyzed using molecular biology techniques.

Metabolomics of cerebrospinal fluid from humans treated for rabies.

Rabies is a rapidly progressive lyssavirus encephalitis that is statistically 100% fatal. There are no clinically effective antiviral drugs for rabies. An immunologically naïve teenager survived rabies in 2004 through improvised supportive care; since then, 5 additional survivors have been associated with use of the so-called Milwaukee Protocol (MP).
