National surveillance data were collected to study the outbreak trends of infectious diseases/syndromes before and during the COVID-19 pandemic period, spanning from 2018 to 2022. The study found that out of 4208 outbreaks, 2972 occurred before the COVID-19 period, affecting 147,425 people, while 1236 outbreaks affected 52,324 people during the pandemic. The number of outbreaks for diseases such as acute flaccid paralysis, fever with rashes, leptospirosis, rabies, and scrub typhus increased during the pandemic. The geographic distribution of outbreaks remained similar for some reemerging diseases in both periods. The trends for dengue, Japanese encephalitis, and cholera remained consistent with peaks mostly from July to September in both periods. We observed a considerable reduction in morbidity and mortality due to outbreaks in India during the pandemic. Despite similar distributional patterns, the study indicates a strong suspicion of persistent outbreak-initiating factors, necessitating an efficient and vigilant surveillance system in the country.
国家监测数据被收集用于研究 COVID-19 大流行前后传染病/综合征的爆发趋势，时间跨度为 2018 年至 2022 年。研究发现，在 4208 次爆发中，有 2972 次发生在 COVID-19 之前，影响了 147425 人，而 1236 次爆发影响了 52324 人。在大流行期间，急性弛缓性麻痹、发热伴皮疹、钩端螺旋体病、狂犬病和丛林斑疹伤寒等疾病的爆发数量有所增加。在这两个时期，一些重新出现的疾病的爆发地理分布仍然相似。登革热、日本脑炎和霍乱的趋势与两个时期的 7 月至 9 月的高峰期一致。我们观察到印度在大流行期间由于爆发导致的发病率和死亡率大幅下降。尽管分布模式相似，但该研究强烈怀疑存在持续的爆发引发因素，因此该国需要建立一个高效和警惕的监测系统。
