Providing aid to Wuhan, China amid COVID-19 pandemic

The COVID-19 outbreak was thought to have originated in Wuhan, Hubei Province, China, causing a severe shortage of necessary medical supplies. Utilizing the strong distribution network build by SRL International, H.U. Group Holdings (previously Miraca Holdings) and group companies were able to donate key medical items.

Sanson Project

SRL International believes that by providing quality clinical testing services overseas, we are also contributing to supporting the health of the local people. With our local partners in China, we provided health check-ups to people living in rural areas without adequate medical facilities.
