In this constantly evolving infographic, you can follow the lineages of the pandemic-causing coronavirus COVID-19 that are circulating in Brazil. The infographic is the result of collaboration between researchers from all over Brazil and the GISAID initiative.

LINEAGES
Lineages are defined as entities/organisms that share a common ancestor and show similar mutations. New lineages emerge as the viruses replicate through mutations. The mutations are mostly silent and/or harmful to these entities.

REINFECTION CASES
We call it reinfection when a virus is able to invade and multiply in an organism even after previous contact with the disease and activation of the immune system. Reinfections can occur both by the decrease in effectiveness of the immune response generated (antibody levels reduction, low activity of defense cells, etc.), and by the evolution of the virus, which can generate differences that allow the acquired immunity to escape. A practical way to confirm reinfection is to check genetically whether the virus that caused the first episode of the disease is different from the one that caused the second – to make sure that it is not a single persistent
