Second, to know the truth we need a robust surveillance system providing data that can supplant opinion with fact. It requires constant evaluation of the well, the sick, the new cases, the rate of transmission, the numbers hospitalized, those on ventilators, and those who have died. All by age, sex, race, geography, occupation etc. It requires not only knowing about who has been tested and outcomes of those tests, but also which tests are used. And we must get the truth out quickly and completely.
Third, the truth requires proper responses. Contact tracing and isolation were hallmarks of the smallpox program with labor-intensive work before computers and smart phones were available for workers. In a single state in India, in May 1974, they reported 1,500 new cases a day. That required 1,500 new investigations each day, with the isolation of cases, the locating of contacts, vaccination of contacts and isolation of those with symptoms until a diagnosis could be made. It required tens of thousands of people simply to act as watch guards of the homes of cases and to vaccinate all visitors. All of this with difficult communications and yet currently we hear that contact tracing is not possible until the numbers of cases are reduced. Of course, the diseases are different. A vaccine and the lack of subclinical cases favored smallpox work. However, the approaches to control are similar. A current problem is that testing remains inadequate months after the problem was defined.
