In March and April 2020, some reports have said that wildlife markets in other countries of Asia, Africa, and in general all over the world are also similarly prone to health risks. In April 2020, a group of US lawmakers, NIAID director Anthony Fauci, UNEP biodiversity chief Elizabeth Maruma Mrema, and CBCGDF secretary general Zhou Jinfeng called for the global closure of wildlife markets due to the potential for zoonotic diseases and risk to endangered species. In April 2020, the World Health Organization announced that it is developing food safety and hygiene standards that wet markets must adhere to before opening.
