On February 5th, local time, WHO held a regular press conference on COVID-19.
In response to a question from the WHO emergency programme, WHO is carrying out a number of different virus traceability efforts, including following up research on wastewater, serum and clinical samples in 2019, including through an international laboratory network, Maria van Kokhov, technical director of the WHO Health Emergency Project, said.
At the same time, contact the researchers directly to discuss their findings to determine whether further cooperation can be carried out and whether there are still residual samples. Many cooperations have been carried out.
