A new mathematical and statistical method allows the virus population in a diseased organism to be determined quickly and economically. Using this method, medicines and vaccines against diseases caused by viral infections could be developed and deployed in a more targeted way in the future. Through their diversity resulting from continuous mutation, viruses easily develop drug resistance. This is also why the manufacture of a vaccine against HIV has been unsuccessful up to now. To bring both under control, the strains of virus present in the host must be known. A new method developed by researchers from Switzerland and America now promises help in identifying diverse virus populations.
