Chinese officials have said the virus emerged from wildlife sold for food at a local wet market.
Many Wuhan residents expressed to AFP journalists a continued fear about resuming normal activities.
A 59-year-old shopkeeper who gave only her surname, Zhou, has reopened her little store, but says people are too scared to come out and shop.
Dancing outside the shop to get the blood flowing, Zhou said she also fears moving around the city, rarely going out and only for essentials while wearing protective clothing, mask and gloves.
“It’s really hard now. I know some people who have been infected. It’s really scary,” she said.
Traffic has picked up after a ban on leaving the city was lifted on Wednesday, but vast numbers of businesses remain closed and plastic barriers in streets hamper movement.
“The ban is not lifted, not in residential compounds. There’s not much change,” Zhou said.
