China News Client April 10 (Yuan Xiuyue) On the 10th, a member of the National Health and Health Commission high-level expert group Zeng Guang made a guest interview with China News. Talking about the development trend of the global epidemic situation, he believes that developing countries are the next decisive battlefield. "If China is the first stage, European and American countries are the second stage, and the third stage should be a developing country, especially in Africa, South Asia, and Latin America. These countries may have relatively large problems in detection power and treatment capacity. We do n’t know how long the epidemic will last there. "
