*App-based contact tracing may significantly reduce the pandemic spread in many countries*Pandemic drone designed to monitor people with infections could limit fatality in hotspotsScientists have made breakthroughs in using technology to tackle the novel coronavirus .
This could significantly reduce the overall rate of spread of the virus, paving the way for what the authors call “intelligent social distancing,” rather than national lockdown. A suppression strategy requires widespread social distancing until scientists can produce an effective vaccine. While this approach has reduced the overall level of mortality, it is also likely to have a range of negative social, economic, and ethical effects.
The challenge, however, is that current approaches to contact tracing take a relatively long time, and the longer contact tracing takes, the more time the virus will have to spread to other hosts. The model suggests that ideas and information spread and evolve between individuals with patterns similar to genes in that they self-replicate mutate and respond to selective pressure as they interact with their host.
In the future, the team hopes that their research can be used to improve the tracking of epidemics and pandemics by accounting for mutations in diseases and ultimately considering interventions like quarantines and then predicting how those interventions would affect an epidemic’s spread when the pathogen is mutating as it spreads.
The question of masks has roiled society as well, with some retailers refusing to let employees wear them for fear of sending negative signals to customers, and cases of slurs and even physical attacks in the United States and elsewhere against Asians or Asian Americans who were wearing masks, a measure some consider a necessity during a disease outbreak.
Previous studies have shown that coronavirus and other respiratory infections are mostly spread during close contact, which has been interpreted by some infectious disease specialists to mean that the disease could spread only through contact and large droplets, such as from a cough or sneeze — a message that has often been shared with the public.
The pandemic drone is being developed in collaboration with the University of South Australia and drone maker Draganfly.
