An adult patient with suspected of monkeypox infection differential diagnosed to chickenpox.

BACKGROUND

Monkeypox is a zoonosis. The disease has a similar appearance to chickenpox caused by the varicella-zoster virus (VZV). On May 9th 2019, there was one laboratory-confirmed case of monkeypox reported in Singapore. A man was also suspected of having monkeypox on June 1st 2019 in Surabaya, Indonesia, a neighboring country.

OBJECTIVE

To report on a suspected case of monkeypox with differential diagnosis to chickenpox.

CASE: A 51-year-old male was suspected of having monkeypox after a differential diagnosis of chickenpox. His chief complaint was multiple blisters on his body. From the dermatological status on his facial, trunk and extremity regions, there were multiple pleiomorphic vesicles, some with umbilication, with a centripetal distribution, and crusts.

METHODS AND

RESULTS

A PCR using VZV specific primers, followed by genome sequencing showed homologies of more than 99 % to other VZVs and less than 50% to Monkeypox sequences.

CONCLUSION

Molecular laboratory techniques have confirmed the case as chickenpox.
