Frequently Asked Questions
  • Why does this dashboard look different to other diseases? For widespread diseases like COVID-19 and flu, wastewater concentration levels and maps are calibrated using data from thousands of confirmed cases. Measles is much rarer. Because there have been no confirmed measles cases in Boston so far this year, wastewater testing is being used instead as an early warning system to detect when the virus first enters the community. As a result, the information shown on this dashboard looks different.
  • How should health care providers interpret these data? A positive wastewater test indicates that one or more people infected with measles were present in Boston on that date, but we cannot tell if they are still in Boston or how many people they potentially exposed while here. Public health officials monitor for related cases, for 6 weeks (two incubation periods) after a known exposure, so BPHC recommends that providers remain vigilant for possible measles cases for the same duration, especially among unvaccinated or under-vaccinated populations.
Measles Data

The red line on the COVID-19 wastewater concentration figure marks the date the lab testing wastewater for BPHC switched. Data before and after this switch may not be comparable.
