The outbreak of the new coronavirus pandemic (SARS-CoV-2) was initiated in December 2019, and within a couple of months it became a global health emergency. Given the importance to assess the evolution and transmissibility of SARS-CoV-2 and to forecast the next scenario of the pandemic, mainly in countries with limited healthcare systems, we estimated the reproductive number (R0) of SARS-CoV-2 in Jammu and Kashmir (J&K), India, and a possible scenario for this pandemic in the region.
We estimated the reproductive number (R0) of SARS-CoV-2 in its first outbreak stage in the northwestern region of Himalaya, India, and we also predicted new daily cases for the next 90 days using different R0, testing a plausible end of the SARS-CoV-2 outbreak.
Our results showed a considerable increase in the number of cases, but with a tendency to asymptote. Anantnag, Bandipora, Baramulla, Shopian, and Srinagar districts showed more than 100 cases and Kulgam and Kathua districts showed strong growth of the number of cases from the beginning of May, without a tendency to normalization. The estimated R0 for the J&K region was 1.041; but by decreasing the RO by 10, 25, and 50%, we observed a great decrease in the daily number of new cases, especially by decreasing by 50%.
In this study, we indicate positive effects of the preventive measures, such as lockdown and social distancing, taken in the J&K region, showing a stabilization of the growth curves of new cases of SARS-CoV-2, which tends to a strong decrease over time as the R0 decreases.
新型冠状病毒大流行(SARS-CoV-2)于2019年12月爆发,在短短几个月内就成为全球卫生紧急事件。鉴于评估SARS-CoV-2的演变和传播能力以及预测大流行的下一步情况非常重要,特别是在医疗系统有限的国家,我们估算了印度查谟和克什米尔地区(J&K)SARS-CoV-2的繁殖数(R0)以及该地区大流行的一种可能情况。
我们估算了印度喜马拉雅西北部地区SARS-CoV-2首次爆发阶段的繁殖数(R0),并使用不同的R0预测了未来90天的每日新增病例数,以此测试SARS-CoV-2爆发的一个合理结局。
我们的结果显示病例数有显著增加,但有趋于平稳的趋势。阿南特纳格、班迪普尔、巴拉穆拉、绍皮恩和斯利那加等地区报告了100多例病例,而库尔加姆和卡图阿地区自5月初以来病例数增长强劲,且无趋于正常化的趋势。J&K地区估算的R0为1.041;但将R0分别降低10%、25%和50%后,我们观察到每日新增病例数大幅下降,尤其是降低50%时。
在本研究中,我们指出了J&K地区采取的封锁和社交距离等预防措施的积极效果,显示出SARS-CoV-2新增病例增长曲线趋于稳定,随着R0降低,新增病例数随时间推移有大幅下降的趋势。
