Malaria causes significant morbidity and mortality worldwide, disproportionately impacting sub-Saharan Africa. Disease phenotypes associated with infection can vary widely, from asymptomatic to life-threatening. To date, prevention efforts, particularly those related to vaccine development, have been hindered by an incomplete understanding of which factors impact host immune responses resulting in these divergent outcomes.

The COVID-19 pandemic is one of the fastest evolving pandemics in recent history. As such, the SARS-CoV-2 viral evolution needs to be continuously tracked. This study sequenced 1123 SARS-CoV-2 genomes from patient isolates (121 from arriving travellers and 1002 from communities) to track the molecular evolution and spatio-temporal dynamics of the SARS-CoV-2 variants in Ghana.

Article Synopsis
  • - Governments worldwide adopted varying strategies to combat COVID-19, with some aiming for herd immunity despite the WHO deeming it unethical, leading to increased viral diversity and potential health risks.
  • - A study utilizing the CovidSim model investigated the impact of multi-infections on COVID-19 morbidity and mortality in the U.S., simulating scenarios of contact reductions and the spread of infections.
  • - Results showed that while multi-infections could lead to fewer overall infections due to higher isolation rates, they significantly increased mortality, highlighting the effectiveness of a potential second lockdown in reducing infections and deaths.
