Taiwan’s health ministry on Thursday urged the elderly, very young and those with poor immunity to avoid travel to China due to the recent increase in respiratory illnesses there, a move some experts said was ineffective to manage public health risks.

The World Health Organization (WHO) last week requested China provide detailed information on the spike, which a WHO official said was not as high as before the COVID-19 pandemic and that no unusual or novel pathogens had been detected.

Taiwan has been wary of disease outbreaks in its giant neighbour since the Severe Acute Respiratory Syndrome (SARS) outbreak that started in China and killed nearly 800 people globally in 2002-2003.

China, whose government claims democratically governed Taiwan as its own, initially tried to cover up that outbreak.
