Global migration patterns of HIV-1 subtype B estimated by statistical phylogeography under the geographical grouping strategy 1. Colors indicate different geographic regions (highlighted countries) from which HIV-1 sequences were available. Arrows indicate the direction of subtype B spread. Dots for different geographic areas are placed in the center of each area.
For the first time, an international team of scientists from the European Society for Translational Antiviral Research (ESAR) has mapped the spread of the HIV virus around the globe after it reached the United States in the early 1970s.
The major study, published in the Journal of Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases (MEEGID), finds that HIV travelled from the US to Western Europe on a number of occasions, whereas Central and Eastern Europe remained isolated for the most part of the early epidemic.
