Aim: To estimate the CFR in Andhra Pradesh during the pandemic in different phases. Methods: All the secondary data were collected either from the covid19india website or github website or Indian government websites or Andhra Pradesh State government website or media quoting the government announcements January 30, 2020 to August 8, 2020. The CFR was estimated as per the Methods for Estimating the Case Fatality Ratio for a Novel, Emerging Infectious Disease. Results: In the pre-lockdown phase, the CFR of Andhra Pradesh was 0.00%, Uttarandhra, Central Andhra & Rayalaseema was Nil, and South Andhra it was ranging from Nil-0.00%, In lockdown phase, the CFR Andhra Pradesh was ranging from 1.34 to 42.31%, Uttarandhra - Nil -5.56%, Central Andhra - Nil-100.00%, South Andhra - 0.00-66.67%, and Rayalaseema - Nil-100.00%.
