Coronavirus Disease 2019 (COVID-19) – Epidemiology Analysis and Forecast – April 2020

Pages: 35 Published: April 30, 2020 Report Code: GDHCHT093

First reported in Wuhan, China, in December 2019, now more than 846,200 confirmed cases of COVID-19 are spread across 187 countries worldwide. The US is now the most heavily affected country worldwide. Forecasts expect new cases to decrease for most countries in the top markets reporting cases except for Russia, which has not yet reached peak.

People at risk for severe COVID-19 include population with underlying health problems, such as respiratory disease, cardiovascular disease, cancer, diabetes, some rare diseases, and diabetes. New analysis available this month for severely obese populations likely to be at risk for sever COVID-19.

The global CFR has increased to more than 7%. The age groups most affected by the disease remains those ages 50 years and older, and men are reported to see higher rates of deaths.

The epidemiology analysis is limited by several data restrictions. Testing availability and criteria differ significantly among countries. All countries’ reported confirmed cases underestimate the number of actual infected people. And mortality reporting is not standardized.


The epidemiology report covers the following areas: current epidemiology situation and forecast, populations at risk, case fatality rate, testing and undiagnosed cases comparison, and data limitations.

The forecast include three-scenario analysis of peak-week and return-to-normal week analysis for the top markets. The populations at risk area focuses on 9MM (US, France, Germany, Italy, Spain, UK, Japan, China, and South Korea) and provides size of the populations that have COPD, heart disease, diabetes, select rare diseases and diabetes. The case fatality rate area provides comparison in case fatality and proprotion of deaths by age in six major markets (Netherlands, China, South Korea, US, and Italy). Data limitations provide readers with in-depth understanding of the caveats surronding the COVID-19 data.

Key Highlights

The report provide forecast for peak-week and return-to-normal week that will help the reader plan in this uncertain time.
