A prospective survey of social mixing patterns relevant to respiratory disease transmission by large droplets (e.g., influenza) or small droplet nuclei tuberculosis) was performed in a South African township 2010. total 571 randomly selected participants recorded the numbers, times, and locations close contacts (physical/nonphysical) indoor casual met daily. The median number physical 12 (interquartile range (IQR), 7–18), 20 (IQR, 13–29), 30 12–54). Physical were most frequent...
Tuberculosis transmission is determined by contact between infectious and susceptible individuals. A recent study reported a 4% annual risk of child tuberculosis infection in southern African township. model was used to explore the interactions prevalence adult infection, adult-to-child contacts, household ventilation, which could result such high infection.Number residents per incidence were derived from census community registers. Using Wells-Riley equation probability analyses adults with...
Background The Australian Government implemented a national vaccination campaign against COVID-19 beginning February 22, 2021. roll-out was criticised for being delayed relative to many high-income countries, but high levels of coverage were belatedly achieved. large-scale Omicron outbreak in January 2022 resulted massive number cases and deaths, although mortality would have been far higher if not vigorous efforts rapidly vaccinate the entire population. impact assessed over this extended...
Modelling disease dynamics is most useful when data are limited. We present a spatial transmission model for the spread of canine rabies in currently rabies-free wild dog population Australia. The introduction sub-clinically infected from Indonesia distinct possibility, as spillover infection dogs. Ranges parameters were estimated literature and expert opinion, or set to span an order magnitude. Rabies was judged have spatially if new infectious case appeared 120 km index case. found 21%...
Despite consistently meeting international performance targets for tuberculosis case detection and treatment success, areas where is hyperendemic fail to achieve the predicted epidemiological impact. In this article, we explore anomalous relationship between defined actual reduction in transmission.In endemic, poorly ventilated social gathering places such as shebeens (informal alcohol drinking places), minibus taxis, clinic waiting rooms are all potential transmission hot spots. We modeled...
Background: The Australian Government implemented a national vaccination campaign against SARS-CoV-2 on February 22, 2021, but the roll out was initially slow and widely criticised. After January 2022, large-scale Omicron outbreak resulted in massive number of cases deaths, although mortality rates would have been far higher if not for invigorated efforts to rapidly mass vaccinate entire population. This is first assessment population impact campaign.Methods: Limited publicly accessible data...
