Sunlight appears to have "powerful" effect on killing virus, DHS says
Acting US Under Secretary of Science and Technology at DHS Bill Bryan said Thursday that emerging research has shown that solar light appears to have a "powerful" effect on killing the coronavirus.
The virus "dies the quickest in the presence of direct sunlight," Bryan told reporters at the Coronavirus Task Force briefing.
According to a slide shown at the daily White House Coronavirus Task Force briefing, the virus has a half life of 18 hours on a surface when it's 70-75 degrees, with 20% humidity and no sunlight. But when the humidity rises to 80% and sunlight increases, the virus' half life drops to two minutes.
Bryan talked about the existence on playground equipment as an example: In the sunlight, the virus would die very quickly, he said, although parts of the equipment in the shade would not be affected in the same way.
These studies may help guide governors in their decisions about what to open and when, Bryan added.
Bryan also said that bleach kills the virus in about five minutes, while isopropyl alcohol takes just 30 seconds.

Speaking at a briefing in Denmark, WHO Europe director Dr. Hans Kluge said a "deeply concerning picture" was emerging of the impact of COVID-19 on long-term homes for the elderly, where care had "often been notoriously neglected".
He went on to say that health workers in such facilities were often overworked and underpaid and called for them to be given more protective gear and support, describing them as the "unsung heroes" of the pandemic.

Medical Studies and Surveys
A survey of more than 200 patients in Italy found that 67% reported an altered sense of taste or smell either right before or right after they tested positive for Covid-19.
In a recent study of New Yorks largest health system, published in the Journal of the American Medical Association, it found that, overall, about 20% of Covid-19 patients treated at Northwell Health died, and 88% of those placed on ventilators died. A ventilator is a device that forces air into the lungs of patients who cannot breathe on their own because of severe pneumonia or acute respiratory distress syndrome.
Luckily, just 12% of the patients in the study needed ventilators, Dr. Safiya Richardson at the Feinstein Institutes for Medical Research, Northwell Health, and colleagues found.
The team looked at the electronic health records of 5,700 patients with coronavirus disease hospitalized at Northwell Health. Final outcomes were known for 2,634 of them.
The records support what doctors have been saying about the coronavirus: most people who become severely ill have some sort of so-called underlying condition. More than half, or 57%, had high blood pressure, 41% were obese and 34% had diabetes.
New York antibody study estimates 13.9% of residents have had the coronavirus
An estimated 13.9% of the New Yorkers have likely had Covid-19, according to preliminary results of coronavirus antibody testing released by Gov. Andrew Cuomo, suggesting that some 2.7 million people across the state may have been infected.
The state randomly tested 3,000 people at grocery stores and shopping locations across 19 counties in 40 localities, Cuomo said.
What we found so far is that the state-wide number is 13.9% tested positive for having the antibodies. What does that mean? It means these were people who were infected and who developed the antibodies to fight the infection, he said.
Cuomo said that the survey was preliminary and limited by other factors. He said the testing targeted people who were out in society shopping, meaning that they may be more likely to be infected than people isolating at home.
