South Korea's response to Covid-19 has been widely praised. The reason for their success is contact tracing. They have been able to quickly identify people exposed to the virus and the citizens comply with a 2 week quarantine to stop the spread.
I am in favor of adopting Japan's strategy, which has proven most effective in the fight against super-spreaders. The Japanese didn't impose a strict lockdown during the first wave, but they were roughly as successful as we were. That is exactly what we need for the second wave. The virologist Christian Drosten (one of Germany’s leading figures in the COVID-19 crisis) also sees this strategy as the correct course of action.
Contact tracing is the public health practice of informing people when they've been exposed to a contagious disease. As it has become more widely employed across the U.S., it has also become mired in modern political polarization and conspiracy theories.
Most discussion on contact tracing apps is centered around the issue of privacy, so one of my roles has been to shed light on the underlying security issues that may make it easier for attackers to tamper with contact tracing apps and potentially breach privacy on a massive scale.
A story about testing, contract tracing and controlling the spread of the virus. Cultural taboos and privacy issues can be a detriment to stopping the spread of the virus as we learn from this story
Where people travel and how long they stay away from home can be measured with smartphone location data. But the increasingly popular movement maps derived from this data don’t reveal how well people maintained social distancing once they reached their destinations
A five-hour online course created by Johns Hopkins Bloomberg School of Public Health could become the backbone of the country's contact tracer training program. The class, which rolled out Monday, offers online instruction to anyone who wants to learn the basics of contact tracing: the process of identifying and isolating people who have been infected with COVID-19 and their close contacts.
The main job is to contact people who have been exposed to the coronavirus by a person who has tested positive. Some people are a little suspicious. Some people hang up after I ask for their date of birth and address. I understand that, the mistrust of the government, having grown up under communism.
The coronavirus SARS-CoV-2 is often spread through sneezes and coughs, but it also leaves the human body through our waste. Scientists around the world are now testing sewage for the virus, using it as a collective sample to measure infection levels among thousands of people.
Researchers are using mobility data prior to the lockdown, and comparing it to the current mobility numbers to determine how to emerge from the lockdown without triggering major resurgence in the outbreak. The researchers admit that their conclusions are highly uncertain and more data is needed.
