 We have published a <a href="https://epjdatascience.springeropen.com/articles/10.1140/epjds/s13688-021-00302-w">new paper in EPJ Data Science</a> describing contact patterns measured in a rural village in Malawi. This study, conducted in collaboration with the University of Zurich and the College of Medicine in Lilongwe, and funded by UNICEF Malawi, represents the first detailed characterization of face-to-face contact patterns in a rural African setting.
 
 Using wearable proximity sensors, we measured contact patterns among 164 individuals over five days in a village in southern Malawi. The data reveal contact patterns that differ substantially from those observed in high-income countries, with implications for understanding respiratory disease transmission in low-resource settings. The study highlights the importance of collecting empirical contact data across diverse populations and environments to inform public health interventions.

 We have published a <a href="https://doi.org/10.7554/eLife.84753">new paper in eLife</a> on SARS-CoV-2 transmission in South African households. This study combines wearable proximity sensors with virological data to assess the association between close-range contact patterns and SARS-CoV-2 transmission within households.
 
 The study involved 340 individuals (88 index cases and 252 household members) who wore proximity sensors for two weeks after SARS-CoV-2 was identified in the household. While viral load and demographic factors were associated with transmission risk, we did not find an association between close-range proximity events and SARS-CoV-2 acquisition. These findings may suggest that airborne transmission in shared household spaces plays a larger role than droplet-mediated transmission during close-proximity contacts, or may reflect the high baseline contact rates within households.
