  • Research summary

    Infection with monkeypox virus in humans occurs through skin or mucous membrane contact with an infected animal or human’s skin lesions, body fluids and respiratory droplets. The aim of this research is to establish how long a patient with monkeypox is infectious for. There were 7 patients in the uk who had monkeypox and provided samples from various sites (the rash, blood, urine, throat swabs) during their illness for clinical monitoring. Monkeypox virus was detected on standard tests (PCR) for a long time and the patients were required to wait in a specialist unit in the hospital. Detecting the virus by PCR does not give a clear indication of whether that virus would actually infect another person, particularly late in the illness during the recovery phase.
    We aim to establish whether a PCR-positive sample is infectious at various stages, using the PCR result level (the Ct value) to provide a “cut off”. We will do this by applying the samples to cells to see whether the cells become infected.
