Monkeypox virus is a DNA virus that causes monkeypox. Symptoms include fever, lymphadenopathy, and vesicular lesions. This study used cell culture as a proxy for infectivity and found that infectious mpxv could be recovered from clinical samples up to 25 days after illness onset.
Monkeypox virus (mpxv) is a DNA virus in the Orthopoxvirus genus which causes Mpox (previously monkeypox). Symptoms include fever, lymphadenopathy and vesicular lesions. There is limited evidence for the duration of mpxv infectivity. This study used cell culture as a proxy for infectivity. Clinical samples from four patients with Mpox were inoculated into African green monkey kidney (Vero E6) cells and monitored for cytopathic effects (CPE). From one patient, infectious mpxv was recovered 25 days after illness onset. Infectious virus was not isolated from samples with an Orthopoxvirus polymerase chain reaction (PCR) Ct value over 31.0, nor from urine.Crown Copyright & COPY; 2023 Published by Elsevier Ltd on behalf of The Healthcare Infection Society.
