Kiwi nurse on Covid-19 in New York

The United States has been wracked by Covid-19 this year -- with more than 19 million cases and 330 thousand deaths across the country. New York City seemed to successfully fight off a spiralling outbreak of the virus earlier in the year, only for a second wave to consume the city in time for the holidays. Kiwi nurse Simone Hannah-Clark works at New York's Mt Sinai ICU and says through her job, she's seen the best and worst of humanity in the last few months.
