Sushil Devare and Katharine Qiu have a lot in common. Both are scientists. Both have helped develop technologies that hunt for viruses. Both have worked around the clock to develop first-ever diagnostic tests while racing against worldwide outbreaks – 35 years apart. Though the two share a unique experience, their two battles against HIV and COVID-19, respectively, were different. Dr. Sushil Devare, a retired Distinguished Research Fellow at Abbott, experienced some of the proudest moments of his career about 35 years ago as he and his Abbott colleagues tracked, analyzed and developed a diagnostic test for HIV. When he initiated research on novel viruses at Abbott, not much was known about HIV. The virus implicated in the development of AIDS was identified in 1983, however, there was no test to diagnose HIV infected individuals. There was an urgent need to stop transmission of HIV, especially through blood supply. There were no therapeutic treatment options. The team knew they had a job to do.
