Details and patient eligibility

About

The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. The first urgent recruitment of blood donors had been implemented during the period from 30 April to 10 May via emergency recruitment SMS . This second repeat trial has been designed to further confirm the results from the the first recruitment by comparing which information extraction frameworks would be more sensitive to blood donors in emergency situations.
