On the Use of Human Mobility Proxies for Modeling Epidemics

On the Use of Human Mobility Proxies for Modeling Epidemics | Avian influenza virus A(H7N9) | Scoop.it

The spatial dissemination of a directly transmitted infectious disease in a population is driven by population movements from one region to another allowing mixing and importation. Public health policy and planning may thus be more accurate if reliable descriptions of population movements can be considered in the epidemic evaluations. Next to census data, generally available in developed countries, alternative solutions can be found to describe population movements where official data is missing. These include mobility models, such as the radiation model, and the analysis of mobile phone activity records providing individual geo-temporal information. Here we explore to what extent mobility proxies, such as mobile phone data or mobility models, can effectively be used in epidemic models for influenza-like-illnesses and how they compare to official census data. By focusing on three European countries, we find that phone data matches the commuting patterns reported by census well but tends to overestimate the number of commuters, leading to a faster diffusion of simulated epidemics. The order of infection of newly infected locations is however well preserved, whereas the pattern of epidemic invasion is captured with higher accuracy by the radiation model for centrally seeded epidemics and by phone proxy for peripherally seeded epidemics.

An H7N1 influenza virus vaccine induces broadly reactive antibody responses against H7N9 in humans.

Emerging H7N9 influenza virus infections in Asia have once more spurred the development of effective pre-pandemic H7 vaccines. However, many vaccines based on avian influenza viruses - including H7 - are poorly immunogenic as measured by traditional correlates of protection. Here we re-evaluated sera from an H7N1 human vaccine trial performed in 2006. We examined cross-reactive antibody responses to divergent H7 strains including H7N9, dissected the antibody response into head versus stalk reactive antibodies, and tested the in vivo potency of these human sera in a passive transfer H7N9 challenge experiment in mice. Although only a low percentage of vaccinees induced neutralizing antibody responses against the homologous vaccine strain and also H7N9, we detected strong cross-reactivity to divergent H7 HAs in a large proportion of the cohort using a quantitative ELISA method. Furthermore, H7N1 vaccination induced antibodies to both the head and the stalk domain of the HA which is in sharp contrast to seasonal inactivated vaccines. Finally, we were able to show that both, neutralizing but also non-neutralizing antibodies improved in vivo virus clearance in a passive transfer H7N9 challenge mouse model.
