Low and middle income countries (LMIC) are as equally affected by the COVID-19 pandemic as more affluent ones. There is a lack of testing and vaccination data, which results in inaccurate information about the number of cases, and makes it difficult to forecast the pandemic evolution and devise interventions. CoronaSurveys is a system to continuously collect data via anonymous surveys. We will deploy this to accurately determine incidence and other factors (e.g. vaccine uptake) in LIMC's.
