What does the 'R' number of coronavirus actually signify?

One figure in particular is being closely scrutinised as ministers decide when to end lockdownR, or the “effective reproduction number”, is a way of rating a disease’s ability to spread. It’s the average number of people on to whom one infected person will pass the virus. For an R of anything above 1, an epidemic will grow exponentially. Anything below 1 and an outbreak will fizzle out – eve ntually.At the start of the coronavirus epidemic, the estimated R for coronavirus was between 2 and 3 – higher than the value for seasonal flu, but lower than for measles. That means that each person would pass it on to between two and three people on average, before either recovering or dying, and each of those people would each pass it on to a further two to three others, causing the total numbe r of cases to snowball over time.Continue reading...

In early April, about four months after a new, highly infectious coronavirus was first identified in China, an international group of scientists reported encouraging results from a study of an experimental drug for treating the viral disease known as COVID-19. It was a small study, reported in the New England Journal of Medicine, but showed that remdesivir, an unapproved drug that was originally developed to fight Ebola, helped 68% of patients with severe breathing problems due to COVID-19 to improve; 60% of those who relied on a ventilator to breathe and took the drug were able to wean themselves off the machines after 18...

Three months. That’s as long as Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health, is willing to wait to get a vaccine candidate against the latest coronavirus that he can start testing in people. Since the virus was identified for the first time in people who fell ill with pneumonia-like symptoms in Wuhan, China, last December, the World Health Organization has declared this coronavirus outbreak, named 2019n-CoV, a public health emergency of international concern. In just over a month, more 11,000 people have tested positive for the virus in...

As a novel coronavirus known as 2019-nCoV continues to spread throughout China and to countries across the world, the big question is: How long will the outbreak last—and how bad will it get? While some doctors have made predictions and outbreaks of similar coronaviruses like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) provide clues, the short, if unsatisfying, answer is that no one is exactly sure. “There is no scientist nor sage on the planet that will tell you when the peak of this epidemic will occur,” said Dr. Michael Ryan, executive director of the World Heal...

It was initially known to be transmitted from animals to human, and was just confirmed to be transmitted from human to human. The rapid nature of its origin and speed in transmission reminds us that national security is threatened when ...
