Scientists from the University of Hong Kong reported Monday the case of a 33-year-old man who became reinfected with Covid-19 four and a half months after his first bout.

Dr. Kelvin Kai-Wang To, the microbiologist who led the work, said genome sequencing shows the two strains of the virus are "clearly different", making it the world's first proven case of reinfection.

The paper has been accepted by the journal Clinical Infectious Diseases but not yet published, and some independent experts urged caution until full results are available.

Based on data from South Korea, the United States and Israel analyzing the infections and spread of the coronavirus through children, researchers now believe that children can contract Covid-19 and easily spread it.

A group of 26 researchers from Sweden wrote that "Because children are contagious, can become seriously ill, and it is unclear today how a mild infection affects their future health, we should already at the start of school take measures to keep the infection down".

They recommend sport only outdoors, eating meals seperated in classes, avoiding group tasks and that masks should be worn at all times.

A sample of frozen chicken wings imported from Brazil has tested positive for the novel coronavirus in the southern Chinese city of Shenzhen, authorities said Thursday, the latest in a series of reports of contaminated imported food products.

The coronavirus was detected Wednesday on a surface sample taken from a batch of chicken wings during screening of imported frozen food in Longgang district of Shenzhen, the municipal government said in a statement. Officials did not name the brand.

New Zealand's director general of health Ashley Bloomfield has announced that the country is currently investigating the transmission of Covid-19 by freight. He stated that "we know the virus can survive within refrigerated environments for quite some time" and that one member of the family of four that recently got infected works in a cool store in Auckland.

Surface testing for the store is currently underway to determine if it could be the possible source for the infections. Over the past weeks China has already reported that they found Covid-19 on the packaging of imported frozen seafood.
