How Deadly Is Covid-19? Researchers Are Getting Closer to an Answer Recent estimates suggest the new coronavirus is deadlier than the seasonal flu, though not as lethal as Ebola. Still, Covid-19 is killing more people than a number of deadlier diseases in part because it is more infectious. Brianna Abbott and Jason Douglas WSJ

Research suggests the new coronavirus kills about five to 10 people for every 1,000 that it infects, though rate varies based on age and access to health care

At least 605,782 people globally have died from COVID-19 and 14,576,899 have been infected by the novel coronavirus that causes it, following an outbreak that started in Wuhan, China, in early December. The World Health Organization referred to it as a pandemic on March 11, 2020.

Older Children Spread the Coronavirus Just as Much as Adults, Large Study Finds

Sat, 2020-07-18 18:15 — mike kraft

The study of nearly 65,000 people in South Korea suggests that school reopenings will trigger more outbreaks.

-0-

In the heated debate over reopening schools, one burning question has been whether and how efficiently children can spread the virus to others.

A large new study from South Korea offers an answer: Children younger than 10 transmit to others much less often than adults do, but the risk is not zero. And those between the ages of 10 and 19 can spread the virus at least as well as adults do.

The findings suggest that as schools reopen, communities will see clusters of infection take root that include children of all ages, several experts cautioned.

“I fear that there has been this sense that kids just won’t get infected or don’t get infected in the same way as adults and that, therefore, they’re almost like a bubbled population,” said Michael Osterholm, an infectious diseases expert at the University of Minnesota....

A guide to WHO’s guidance on COVID-19

There’s a lot of information out there about how governments, health professionals and the general public should respond to the COVID-19 pandemic. WHO has published guidance and advice every step of the way.

During health emergencies like the COVID-19 pandemic, one of WHO’s most vital roles is to gather data and research from around the world, evaluate it, and then advise countries on how to respond.

Rigorous wildlife disease surveillence needed

Fri, 2020-07-10 19:55 — mike kraft

Rigorous wildlife disease surveillance Evidence suggests that zoonotic (animal origin) coronaviruses have caused three recent emerging infectious disease (EID) outbreaks: severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the current coronavirus disease 2019 (COVID-19) pandemic. In the search for an intermediate host for SARS coronavirus 2 (SARS-CoV-2, which causes COVID-19), studies have identified SARS-CoV-2–like strains in bats ([ 1 ][1]) and pangolins ([ 2 ][2]), but these do not contain the same polybasic cleavage site that is present in SARS-CoV-2 ([ 3 ][3]).

China and Mekong Dams

China and the Cascading Geopolitics of Lower Mekong Dams

Much has been written on the downstream impact of China’s dams on the Lancang-Mekong River, which flows through or along the borders of five other countries after exiting China. Most of the discussion relates to the hydrological impact of impounding water in the eight dams along the mainstream Lancang Jiang in Yunnan Province. Particular concern surrounds the recently completed Xiaowan Dam and the recently approved construction of the Nuozhadu Dam, each of which is of a scale to impound quantities of water that can affect river hydrology throughout the basin. The Lancang Cascade, as it is termed, has caused considerable controversy in downstream countries, most notably during the 2008 floods and the 2010 drought. Both the floods and the droughts were blamed by many in Thailand, and some in Laos, Cambodia and Vietnam, on China’s actions. Recent articles on the downstream implications of altered river hydrology and the need for China to be less disingenuous in its public relations over the issue show the confluence of river hydrology and geopolitics in an international river basin such as the Lancang-Mekong.
