The New Zealand and Australian stock markets have posted further losses after the announcement by US President Donald Trump that all flights from Europe to the US will be suspended for 30 days.
Trump made the announcement on Thursday saying the US needs to "keep new cases from entering our shores".
"I will never hesitate to take any of the necessary steps to protect the health, safety and wellbeing of the American people."
Trump said no nation "is more prepared or resilient" than the US.

The fall in the US came as coronavirus was declared a pandemic by the World Health Organization (WHO) on Thursday.
"WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming level of spread and severity and by the alarming levels of inaction," said Director-General Dr Tedros Adhanom Ghebreyesus.
"We have therefore made the assessment that COVID-19 can be characterised as a pandemic."
