Personal View compares transmissibility and mortality rates of SARS-CoV-2 with other coronaviruses and influenza.
Key Points
- This work aims to compare SARS-CoV-2 with other epidemic coronaviruses and pandemic influenza regarding transmissibility, hospitalisation, and mortality rates.
- Comparison of basic reproductive rates (R0) among SARS-CoV-2, SARS-CoV, MERS-CoV, and pandemic influenza viruses.
- Analysis of hospitalisation and mortality data from various countries, focusing on demographic structures and testing strategies.
- SARS-CoV-2 has an estimated basic reproductive rate of 2.5, higher than MERS-CoV's 0.9 and comparable to SARS-CoV's 2.0-3.0.
- All-age mortality rate in Lombardy, Italy, was reported at 154 per 100,000 population.
- Variability in case fatality rates across countries is likely due to differences in testing strategies and demographic factors.
