Reinfection is gradually being recognised after symptomatic or asymptomatic COVID-19 infection. We try to elucidate various explanations behind COVID-19 reinfection and suggest possible strategies to counteract this threat.
We carried out a comprehensive review of the literature using suitable keywords such as 'COVID-19', 'Pandemics', 'Reinfection', 'Vaccines' and 'India' on the search engines of PubMed, SCOPUS, Google Scholar and Research Gate in March 2021 and first half of April 2021 during the current COVID-19 pandemic. Epidemiology, risk factors and trends of reinfection were assessed.
A multitude of factors have been associated with rising incidence of COVID-19 reinfection in India and across the world. Emergence of 'Variants of Concern (VOC)', pandemic fatigue and disregard of infection prevention strategies appear to be the most obvious reasons.
COVID-19 reinfection is an emerging concern amongst the worldwide population with newer mutant strains demonstrating increasing transmissibility and responsible for continuing waves of the pandemic. COVID Appropriate Behaviour (CAB), improvised vaccines and enhanced vaccination drives are necessary to mitigate global threat.
在出现症状或无症状 COVID-19 感染后，人们逐渐认识到再感染的情况。我们试图阐明 COVID-19 再感染背后的各种解释，并提出可能的策略来应对这一威胁。
我们于 2021 年 3 月至 4 月 COVID-19 大流行期间，在 PubMed、SCOPUS、Google Scholar 和 Research Gate 等搜索引擎上，使用“COVID-19”、“大流行”、“再感染”、“疫苗”和“印度”等合适的关键字，对文献进行了全面综述。评估了再感染的流行病学、危险因素和趋势。
在印度和世界各地，许多因素与 COVID-19 再感染发病率的上升有关。出现“值得关注的变异株（VOC）”、大流行疲劳和忽视感染预防策略似乎是最明显的原因。
COVID-19 再感染是全球范围内一个新出现的问题，新型突变株具有更高的传染性，导致了大流行的持续浪潮。需要采取 COVID 适当行为（CAB）、改进疫苗接种和加强疫苗接种运动来减轻全球威胁。
