Household transmission modeling qualified variation of individual infectiousness among infected persons, which could be caused by both biological factors and host behaviors.

While recognizing study design limitations, the lack of association between household close range proximity events and SARS-CoV-2 transmission, suggests that aerosol transmission may play a larger role than droplet transmission in the household.

Targeting the mothers, and other household members, of newborns with a mixture of respiratory syncytial virus (RSV) vaccines is both efficient and effective at reducing RSV hospitalizations.

Updated estimates of the generation time of SARS-CoV-2 infections indicate that the generation time has become shorter.

Socio-economic hierarchies may be bad for health, even among people living in a relatively traditional, small-scale society in the Bolivian Amazon.

Data analysis and mathematical modelling suggest that subclinical tuberculosis contributes substantially to transmission and needs to be diagnosed and treated for effective progress towards tuberculosis elimination.

While flooding events may drive spillover transmission of Leptospira spp. through dispersal of the bacteria at low elevations, at higher elevations environmental risk is more localised and directly driven by the distribution of local rat reservoir populations.

Insecticide-treated net requirements for Africa have been underestimated, but mitigating for inefficiencies in net distributions can produce a cost effective path to universal coverage.

Differences in patterns of social contact between settings have consequences for the spread and transmission of respiratory pathogens and the effectiveness of different measures aimed at their control.

The increased risk for symptomatic malaria following an asymptomatic Plasmodium falciparum infection supports targeting asymptomatic infections as a tool to reduce clinical malaria in high-transmission settings.
