COVID-19 is an acute respiratory illness caused by Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2). The first case was reported in Africa on February 14, 2020 and has surged to 11 million as of July 2022, with 43% and 30% of cases in Southern and Northern Africa. Current epidemiological data demonstrate heterogeneity in transmission and patient outcomes in Africa. However, the burden of infectious diseases such as malaria creates a significant burden on public health resources that are dedicated to COVID-19 surveillance, testing, and vaccination access. Several control measures, such as the SHEF2 model, encompassed Africa's most effective preventive measure. With the help of international collaborations and partnerships, Africa's pandemic preparedness employs effective risk-management strategies to monitor patients at home and build the financial capacity and human resources needed to combat COVID-19 transmission. However, the lack of safe sanitation and inaccessible drinking water, coupled with the financial consequences of lockdowns, makes it challenging to prevent the transmission and contraction of COVID-19. The overwhelming burden on contact tracers due to an already strained healthcare system will hurt epidemiological tracing and swift counter-measures. With the rise in variants, African countries must adopt genomic surveillance and prioritize funding for biodiversity informatics.
新型冠状病毒肺炎(COVID-19)是由严重急性呼吸系统综合征冠状病毒 2(SARS-CoV-2)引起的急性呼吸道疾病。首例病例于 2020 年 2 月 14 日在非洲报告,截至 2022 年 7 月已增至 1100 万例,其中 43%和 30%的病例分别发生在非洲南部和北部。目前的流行病学数据表明,非洲的传播和患者结局存在异质性。然而,疟疾等传染病的负担给专门用于 COVID-19 监测、检测和疫苗接种的公共卫生资源带来了巨大负担。SHEF2 模型等几种控制措施包含了非洲最有效的预防措施。在国际合作和伙伴关系的帮助下,非洲的大流行防范采用了有效的风险管理策略,以监测在家中的患者,并建立抗击 COVID-19 传播所需的财务能力和人力资源。然而,缺乏安全的卫生设施和无法获得饮用水,加上封锁的经济后果,使得预防 COVID-19 的传播和感染变得困难。已经紧张的医疗保健系统给接触追踪者带来的巨大负担,将影响流行病学追踪和迅速采取对策。随着变异株的出现,非洲国家必须采用基因组监测,并优先为生物多样性信息学提供资金。
