In this paper, we study the incidence of COVID-19 and the associated fatality with altitude using high frequency, district level data from India. To understand the implications of the nationwide lockdown after the outbreak, we use data for about four months- two from the lockdown period starting from March 25 till May 31, 2020 and about two months after unlocking was initiated (June 1-July 26, 2020). The multivariate regression result indicates slower growth in average rate of infection during the lockdown period in hilly regions, the gains of which attenuated after the unlocking was initiated. Despite these early gains, the rate of fatalities is significantly higher during the lockdown period in comparison to the plains. The findings remain robust to multiple alternative specifications and methods including one that accounts for confounding possibilities via unobservable and provides consistent estimates of bias adjusted treatment effects. The evidence supports the need for provisioning of public health services and infrastructure upgradation, especially maintenance of adequate stock of life support devices, in high altitude regions. It also underscores the necessity for strengthening and revising the existing Hill Areas Development Programme and integrating important aspects of public health as part of this policy.
在本文中,我们使用来自印度的高频、地区级数据研究了 COVID-19 的发病率以及与海拔高度的关系。为了了解疫情爆发后全国封锁的影响,我们使用了大约四个月的数据——封锁期间的两个月(从 2020 年 3 月 25 日至 5 月 31 日)和解锁开始后的两个月(2020 年 6 月 1 日至 7 月 26 日)。多元回归结果表明,在丘陵地区,封锁期间平均感染率的增长速度较慢,而解锁后这种增长速度有所减弱。尽管有这些早期的收益,但与平原地区相比,封锁期间的死亡率明显更高。这些发现通过不可观察的因素来解释混杂可能性,并提供了一致的、经过偏差调整的治疗效果估计值,对于多种替代规范和方法仍然是稳健的。该证据支持在高海拔地区提供公共卫生服务和基础设施升级的必要性,特别是维持足够数量的生命支持设备库存。它还强调了加强和修订现有的山区发展计划以及将公共卫生的重要方面纳入该政策的必要性。
