SARS-CoV-2 has a slow evolutionary rate, yet during pandemic rapid transmission enabled it to acquire significant genetic diversity, resulting in the emergence of variants that can impact transmission and infectivity.
Impacts. COVID-19 portal. v. t. e. Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) [2] is a strain of coronavirus that causes COVID-19, the respiratory illness responsible for the COVID-19 pandemic. [3] .
In this study, the infectious mechanism of the coronavirus is explained with a focus on different variants and their respective mutations, which play a critical role in the increased transmissibility, infectivity, and immune escape of the virus.
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with the virus will experience mild to moderate respiratory illness and recover without requiring special treatment. However, some will become seriously ill and require medical attention.
COVID-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2, also called SARS-CoV-2. The coronavirus spreads mainly from person to person, even from someone who is infected but has no symptoms.
30 mar 2022 · We describe how SARS-CoV-2 may infect the lower respiratory tract and cause alveolar damage as a result of dysfunctional immune responses.
5 kwi 2023 · Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused millions of deaths and substantial morbidity worldwide. Intense scientific effort to understand the biology of SARS-CoV-2...
