10月24日0—24时，31个省（自治区、直辖市）和新疆生产建设兵团报告新增确诊病例39例。其中境外输入病例4例，本土病例35例，含5例由无症状感染者转为确诊病例。
针对本轮疫情的源头问题，国家卫生健康委疾控局副局长吴良有表示，本次疫情的病毒为德尔塔变异株，疫情源头目前还在流调溯源中。现有流调和病毒测序结果提示，本次疫情由新的境外输入源头引起。
Epidemiological investigation and viral genome sequencing results in hand have indicated that this new round of COVID-19 infections in China was caused by viruses transmitted from abroad, according to the National Health Commission (NHC).

中国疾控中心免疫规划首席专家王华庆表示，监测结果显示，今年3月以来全国流感活跃度高于去年同期水平，尤其9月以来，我国南方一些省份流感活跃水平呈明显上升趋势。专家研判，今冬明春可能存在新冠肺炎和流感叠加的风险。
Wang Huaqing, chief immunization expert at the Chinese Center for Disease Control and Prevention, said that since March, flu incidence across China has been higher than in the same period last year.
He added that since September, incidence in some provinces in South China has risen significantly. "There is the risk of flu outbreaks this winter and spring," he said. "If the novel coronavirus also spreads, the risk of two viruses circulating simultaneously exists," he said.

疫苗加强针已经开打
本轮疫情来临后，也有不少有关疫苗加强针的问题：哪些人需要打？不断接种新冠病毒疫苗是否会成为一种常态？
吴良有表示，完成国药中生北京公司、北京科兴公司、国药中生武汉公司的灭活疫苗和天津康希诺公司的腺病毒载体疫苗全程接种满6个月的18岁及以上人群，可进行一剂次加强免疫。
Wu Liangyou said that China has recently begun administering booster shots to people aged 18 years and older who have been fully vaccinated with domestic vaccines for at least six months.

吴良有介绍，加强免疫接种目前优先在感染高风险人群和保障社会基本运行的关键岗位人员中开展。同时，各地要统筹考虑口岸、边境、重大活动等疫情防控需要和60岁及以上等感染后导致重症风险高的高危人群等因素，扩大加强免疫接种人群范围。对其他符合条件且有接种需要的人群，也提供加强免疫接种服务。
He said the focus at present is to give booster doses to people at higher risk of contracting the virus and key workers in the public sector. "Meanwhile, we have required local authorities to take their unique circumstances into account-particularly in areas situated near ports and borders and those hosting major events-and consider the needs of people prone to developing serious illnesses," he said.
