印度自2021年3月以来遭受了第二波COVID-19大流行。这波疫情比2020年第一波大流行更为严重，这表明可能存在一些新的传播特征。 COVID-19 通过飞沫、气溶胶和接触受感染的表面传播。空气污染物也被认为与 COVID-19 传播有关。然而，人们对室内传播在 COVID-19 大流行中的作用以及这些因素对室内环境的影响仍知之甚少。我们的研究重点是揭示室内传播在印度第二波 COVID-19 大流行中的作用。我们的结果表明，家庭环境中的人员流动对该国的 COVID-19 日增长率的相对影响最大。在印度大多数邦级地区，COVID-19 日增长率与居民百分比显着正相关。当居住百分比在 100% 至 120% 范围内时，发现显着的正非线性关系。此外，流行病动力学模型表明，家庭环境中室内传播的比例较高，能够加剧印度第二波 COVID-19 大流行的严重程度。我们的研究结果表明，应更加关注家庭环境中的室内传播。通风和集中隔离等减少室内传播的公共卫生策略将有利于 COVID-19 的预防和控制。
India has suffered from the second wave of COVID-19 pandemic since March 2021. This wave of the outbreak has been more serious than the first wave pandemic in 2020, which suggests that some new transmission characteristics may exist. COVID-19 is transmitted through droplets, aerosols, and contact with infected surfaces. Air pollutants are also considered to be associated with COVID-19 transmission. However, the roles of indoor transmission in the COVID-19 pandemic and the effects of these factors in indoor environments are still poorly understood. Our study focused on reveal the role of indoor transmission in the second wave of COVID-19 pandemic in India. Our results indicated that human mobility in the home environment had the highest relative influence on COVID-19 daily growth rate in the country. The COVID-19 daily growth rate was significantly positively correlated with the residential percent rate in most state-level areas in India. A significant positive nonlinear relationship was found when the residential percent ratio ranged from 100 to 120%. Further, epidemic dynamics modelling indicated that a higher proportion of indoor transmission in the home environment was able to intensify the severity of the second wave of COVID-19 pandemic in India. Our findings suggested that more attention should be paid to the indoor transmission in home environment. The public health strategies to reduce indoor transmission such as ventilation and centralized isolation will be beneficial to the prevention and control of COVID-19.
