Swiss pharmaceutical giant Roche announced on Wednesday that it has developed PCR tests to detect monkeypox virus, after several cases emerged in parts of the world where the disease is not common. developed by Roche and its subsidiary TIB Molbiol, “in response to cases of infection with the monkeypox virus which have recently raised concerns”, he said in a press release. “Roche has very quickly developed a new series of tests for the detection of the simian pox virus and the monitoring of its spread”, observed the director of the Diagnostics division of Roche, quoted in the press release. Virus outbreakRecent outbreaks, with more than 250 cases already reported in 16 countries as of May 22 according to the World Health Organization, are atypical because they occur in countries where monkeypox, a disease characterized by skin lesions, is not not endemic. The tests developed by Roche are not intended for the general public but are available for research purposes in most countries of the world. A first kit detects orthopoxviruses, including monkeypox viruses, a second specifically detects monkeypox viruses, while a third kit can detect orthopoxviruses while determining whether a monkeypox virus is present or not.Only effective PCRAccording to the WHO, it is appropriate to detect the disease with a PCR test because antigenic tests cannot determine whether it is monkeypox virus or other related viruses. The best samples for diagnosis come from lesions, swabs of exudates (fluid produced by the wound) or crusts from lesions. Monkeypox or monkeypox is – according to the WHO – a rare viral zoonosis (virus transmitted to humans by animals) whose symptoms are less severe than those observed in the past in people with smallpox.
