How many countries has the new strain of mpox virus currently spread in?

As of my last knowledge update in October 2023, the mpox virus, previously known as monkeypox, had been reported in multiple countries outside of its traditionally endemic regions. However, the exact number of countries experiencing outbreaks of the new strain can change rapidly based on emerging cases and public health responses. For the most accurate and current information, I recommend checking resources such as the World Health Organization (WHO) or the Centers for Disease Control and Prevention (CDC).
