During India's devastating second wave in April-May 2021, the Ministry of Health and Family Welfare reported:

• Peak daily cases: 414,188 (May 6, 2021)
• Daily deaths: 4,529 (May 18, 2021)

长期影响与后疫情术语

Emerging post-pandemic English expressions include:

1. Long COVID (长期新冠): Persistent symptoms lasting weeks or months after infection
