Loss of Smell, Taste May Be Reliable Predictor of COVID-19: Study
Ashley Yeager May 12, 2020 in the Scientist. “Data from a crowdsourcing smartphone app is helping to track the spread of the disease in real time and reveals the symptom as the number one indicator of infection.”
Why is coronavirus deadly for some, but harmless in others?
By Carrie Arnold in New Scientist, May 6, 2020 “To figure out what makes some people more vulnerable to severe cases of covid-19, we need to rethink what we know about infection”

Rapid Expert Consultations on the COVID-19 Pandemic: March 14, 2020-April 8, 2020
THE NATIONAL ACADEMIES PRESS, April 2020. “…the National Academies of Sciences, Engineering, and Medicine convened a standing committee of experts to help inform the federal government on critical science and policy issues related to emerging infectious diseases and other 21st century health threats. This set of Rapid Expert Consultations are the first of their kind and represent the best evidence available to the Committee at the time each publication was released.” Partial list of Topics : Rapid Severe Illness in Young Adults for the COVID-19 Pandemic, Surface Stability and Incubation for the COVID-19 Pandemic (March 15, 2020), Social Distancing, Data Elements and Systems Design for Modeling and Decision Making for the COVID-19 Pandemic…Possibility of Bioaerosol Spread Survival in Relation to Temperature and Humidity and Potential for Seasonality for the COVID-19 Pandemic.
Tracking covid-19 excess deaths across countries
In The Economist,Apr 16, 2020
Matjaž Perc et al., Frontiers in Physics, April 8, 2020. “…we here show forecasts obtained with a simple iteration method that needs only the daily values of confirmed cases as input. The method takes into account expected recoveries and deaths, and it determines maximally allowed daily growth rates that lead away from exponential increase toward stable and declining numbers. Forecasts show that daily growth rates should be kept at least below 5% if we wish to see plateaus any time soon”
A simple iterative map forecast of the COVID-19 pandemic
André E. Botha, Wynand Dednam arXiv:2003.10532 [physics.soc-ph] last revised 2 Apr 2020. (View About arXiv)
“We develop a simple 3-dimensional iterative map model to forecast the global spread of the coronavirus disease. Our model contains only one fitting parameter, which we determine from the data supplied by the world health organisation for the total number of cases and new cases each day. We find that our model provides a surprisingly good fit to the currently-available data. It predicts that the disease will run its full course over six to seven months, starting from the date on which the world health organisation provided the first ‘Situation report’ (21 January 2020 − day 1). The disease may be expected to infect approximately 24% of the global population, i.e. about 1.83 billion people, taking approximately 86 million lives. Unless drastic new interventions become possible, the global number of new cases is predicted to peak on day 129 (about the middle of May 2020), with an estimated 65 million new cases per day. Since our simple model fits the available global data so well, we suggest that the measures being taken so far to contain the pandemic may be ineffective in curbing the global spread of the virus. As such, the efficacy of these measures should be more carefully weighed against their impact on the world economy.”
Stanford researchers show how forest loss leads to spread of disease
STANFORD UNIVERSITY on EurekaAlert Apr 7, 2020 “Viruses that jump from animals to people, like the one responsible for COVID-19, will likely become more common as people continue to transform natural habitats into agricultural land, according to a new Stanford study.”
Human evolution: The astounding new story of the origin of our species

Large scale testing of general population in Iceland underway
Government of Iceland, Updated Mar 21, 2020
– Iceland has tested 9 768 individuals for COVID-19, which translates to 26 762 per million, compared with 6 343 in South Korea and 13 999 in Bahrein
– Iceland has tested a higher proportion of inhabitants than any other country after deCode genetics started offering free screening among the general, non-symptomatic, non-quarantined population
– deCode has published the results of a total of 5 571 tests. Those have yielded 48 positive results (0.86%) indicating that the prevelance of the virus is modest among the general population.
– A total of 473 cases have been identified in Iceland since the first case on February 28th. One person with COVID-19 has died. Twelve individuals with COVID-19 are hospitalized.

The COVID-19 Coronavirus May Travel in Aerosols
Amy Schleunes, Apr 3, 2020 on the-scientist.com “A report from the National Academy of Science, Engineering and Medicine to the White House Office of Science and Technology Policy released on April 1 states that based on current research, SARS-CoV-2 may be spread through aerosols. The letter cites a recent study at the University of Nebraska Medical Center that found “widespread evidence of viral RNA in isolation rooms where patients with SARS-CoV-2 were receiving care” in air and surface samples. Even air collectors that were more than six feet away from patients detected the RNA, calling into question whether current social distancing guidelines are sufficient to prevent the spread of the disease.”

‘Worse’ pandemic on horizon unless world deals with wildlife markets
Mark Gollom · CBC News · Posted: Mar 27, 2020 “The continued existence of wildlife markets, which are considered potential breeding grounds for the spread of harmful viruses, means it’s just a matter of time before the world is hit with another deadly pandemic, some scientists suggest.”
