Despite a massive effort, the nation faces “truly daunting” challenges to deploy millions of coronavirus tests to safely re-open the economy, the head of the National Institutes of Health told lawmakers Thursday.
NIH Director Francis Collins told the Senate Health, Education, Labor and Pensions committee that government and private industry have launched a $2.5 billion, taxpayer-funded effort to develop, manufacture and distribute technology capable of accurately testing millions of people a week by the end of the summer or the fall, before the annual flu season. 
Widespread availability of testing is seen as critical to reopening the economy because it would allow public health officials to identify and contain a rebound of the virus. It remains a high bar to clear.
“I must tell you, senators, that this is a stretch goal that goes well beyond what most experts think will be possible,” Collins said. “I have encountered some stunned expressions when describing these goals and this timetable to knowledgeable individuals. The scientific and logistical challenges are truly daunting.”
