There’s evidence to suggest that most covid-19 infections are transmitted by a select few individuals we call “superspreaders.” What is a superspreader? An unusually contagious individual who’s been infected with disease. They can infect far more than the two to three individuals researchers initially estimated the average infected patient could infect. What’s the impact of superspreaders? Researchers are beginning to come to a consensus after several new studies suggested that the vast majority of people infect very few others or none at all. Lots of outbreaks around the world have been linked to single superspreader  events. For example, a choir practice in Washington State infected about 52 people, and a megachurch in Seoul was linked to the majority of initial infections in South Korea. What makes someone a superspreader? It might have something to do with increased viral loads and shedding more virus than is normal, but we still don’t know what would trigger this, let alone how to identify it through practical means. What do we do about superspreaders? We can’t medically diagnose superspreaders, but we can limit their impact. Contact tracing is critical. Read the full story. —Neel Patel Norway halts coronavirus app over privacy concerns The news: Norway is halting its coronavirus contact tracing app, Smittestopp, after the Norwegian Data Protection Authority said that the country’s low rate of infections meant that the app’s privacy invasions were no longer justified. The app will cease collecting new data, all data collected so far is being deleted, and work on it is effectively paused indefinitely. Contentious: Officials at the Norwegian Institute of Public Health (NIPH) disagreed with the decision. “The pandemic is not over. We have no immunity in the population, no vaccine, and no effective treatment. Without the Smittestopp app, we will be less equipped to prevent new outbreaks that may occur locally or nationally,” NIPH director Camilla Stoltenberg said in a statement on Monday. The context: New contact tracing apps are seeing mixed success as the virus itself continues to ebb and flow around the world. It’s not all bad news, though. Italy was the first country in the continent to be badly hit, and Immuni, the contact tracing app backed by the government in Rome, was released recently to relatively positive reviews and quickly adopted by the Italian residents who are able to download it. However, the reaction to these apps globally has led to profound skepticism about whether they will help fight the coronavirus in most countries.
