The Trump administration has significantly turned to technology to combat the spread of COVID-19. Recently three more US states – Alabama, North Dakota, and Wyoming have launched contact tracing apps to tackle the potential exposure to the infection chain.
The states are warning users about the growing risk and have urged them to download the apps, that are available in both Android and iOS handsets.
These applications track location history and enable mobile phones to exchange Bluetooth signals, in order to keep an unnamed list of close encounters. People who are infected or at high risk can anonymously notify the recent contacts to take precautions.
