Taiwan has found its first locally spread cases of the more contagious clade Ib strain of Mpox, a worrying sign for public health but still a small outbreak overall.

• Two unvaccinated men in their 30s caught the strain inside Taiwan, and health officials cannot trace where the infections came from.
• Clade Ib spreads more easily through close contact and within households than the older strain.
• Children, pregnant women, and people with weak immune systems face the highest risk of getting seriously ill.
• Taiwan's total Mpox cases this year are actually lower than the same point in the past two years.
• Almost 90% of infected people had never been vaccinated, and free shots are available to those at higher risk.

Outlook: Expect health authorities to push harder on vaccination and contact tracing as they watch for further local spread.
