Who gets to be first in line for a COVID-19 vaccine? U.S. health authorities hope by late next month to have some draft guidance on how to ration initial doses, but it's a vexing decision."Not everybody's going to like the answer," Dr. Francis Collins, director of the National Institutes of Health, recently told one of the advisory groups the government asked to help decide. "There will be many people who feel that they should have been at the top of the list."Traditionally, first in line for a scarce vaccine are health workers and the people most vulnerable to the targeted infection.But Collins tossed new ideas into the mix: Consider geography and give priority to people where an outbreak is hitting hardest.And don't forget volunteers in the final stage of vaccine…

Mexico now has the third most COVID-19 deaths in the world, behind Brazil and the United States, where a hurricane bearing down on the East Coast on Saturday is threatening to complicate efforts to contain the virus.Hurricane Isaias' imminent arrival forced the closure of some outdoor testing sites even though Florida has become a major hot spot, and other states in the path of the storm prepared emergency shelters that comply with social-distancing measures."We had to put safety first," Miami-Dade County Mayor Carlos Gimenez said Friday.But Florida Gov. Ron DeSantis said no immediate evacuation orders have been given and that hospitals in general are not being evacuated of coronavirus or other patients.Meanwhile, Mexican health officials on Friday reported 688 new deaths, pushing the country's confirmed total to over 46,600. That…

Connie Culp, the recipient of the first partial face transplant in the U.S., has died at 57, almost a dozen years after the groundbreaking operation.The Cleveland Clinic, where her surgery had been performed in 2008, said Saturday that Culp died Wednesday at the Ohio clinic of complications from an infection unrelated to her transplant.Dr. Frank Papay, chair of Cleveland Clinic's dermatology and plastic surgery institute and part of Culp's surgical team, called her "an incredibly brave, vibrant woman and an inspiration to many.""Her strength was evident in the fact that she had been the longest-living face transplant patient to date," Papay said in a statement. "She was a great pioneer and her decision to undergo a sometimes-daunting procedure is an enduring gift for all of humanity."Culp's husband shot her in…

A pair of NASA astronauts face the final and most important part of their SpaceX test flight: returning to Earth with a rare splashdown.Doug Hurley and Bob Behnken took part in a farewell ceremony Saturday at the International Space Station, several hours ahead of their planned departure on a SpaceX Dragon capsule.  Despite approaching Hurricane Isaias, NASA said the weather looks favorable for a Sunday afternoon splashdown in the Gulf of Mexico near Panama City, Florida. It will be the first splashdown for astronauts in 45 years. The last time was following the joint U.S.-Soviet mission in 1975 known as Apollo-Soyuz.The astronauts' homecoming will cap a two-month mission that ended a prolonged launch drought in the U.S., which has relied on Russian rockets to ferry astronauts to the space station…

There are more than 17.6 million worldwide COVID-19 cases, according to Johns Hopkins statistics.  The U.S. continues to lead in the number of infections with more than 4.5 million, followed by Brazil with 2.6 million cases, and India with almost 1.7 million.Mexico has replaced Britain as the country with the third largest number of deaths from COVID-19. Johns Hopkins says Mexico now has reported 46,688 deaths.The U.S. leads the world in the number of deaths from the virus with more than 153,000, followed by Brazil with more than 92,000.Where Has the New Coronavirus Spread?New virus, denoted 2019-nCoV by the WHO, has caused alarm because of its similarity to SARS in 2002-2003Russia is gearing up to launch a mass vaccination campaign against the coronavirus in September or October.  News media reports…

Amid the chaos of the pandemic's early days, doctors who faced the first coronavirus onslaught reached across oceans and language barriers in an unprecedented effort to advise colleagues trying to save lives in the dark.With no playbook to follow and no time to wait for research, YouTube videos describing autopsy findings and X-rays swapped on Twitter and WhatsApp spontaneously filled the gap.When Stephen Donelson arrived at the University of Texas Southwestern Medical Center in mid-March, Dr. Kristina Goff was among those who turned to what she called "the stories out of other places that were hit before."Donelson's family hadn't left the house in two weeks after COVID-19 started spreading in Texas, hoping to shield the organ transplant recipient. Yet one night, his wife found him barely breathing, his skin turning…

The United States has passed the marker of 150,000 deaths from COVID-19, as some spots around the country continue to see rising case numbers. The political, economic and public health crises are a source of ongoing concern for lawmakers. But the nation’s top health experts did have some encouraging news Friday, telling a congressional panel that development of a vaccine for the virus is proceeding rapidly. VOA's Congressional Correspondent Katherine Gypson has more from Washington. Produced by: Katherine Gypson ...

The World Health Organization on Thursday warned Africa against easing coronavirus restrictions as the number of infections on the continent has doubled in the past month.WHO Regional Director for Africa Matshidiso Moeti said at a virtual news conference, “We are concerned that ... we will see an increase in cases as we have seen in [other] countries” where restrictions have been eased too soon.”She said more than 20 African countries have recorded more new cases than in the previous weeks, with South Africa accounting for the most but increases also reported in Kenya, Madagascar, Nigeria, Zambia and Zimbabwe.Moeti said Uganda, Seychelles and Mauritius are doing well in controlling the virus.The WHO said there have been nearly 890,000 reported coronavirus cases in Africa and 18,000 deaths.World Health Organization (WHO) Director-General Tedros…

Living microbes, possibly millions of years old, have been discovered more than five kilometers beneath the  Pacific Ocean’s surface, in an area believed to have been devoid of life.In a study published Tuesday, Japanese and American scientists described what they found in sediment samples taken from a flat, wide area 3.7 kilometers to 5.7 kilometers below the ocean’s surface, known as an abyssal plain.  Because of their depth and the limited organic material in the sediment found there, these areas were long believed unable to support life.Microbes revived from 101.5 million-year-old sediment cores gathered from beneath the Pacific Ocean floor are seen in an undated magnified image released by the Japan Agency for Marine-Earth Science and Technology in Kochi, Japan July 28, 2020.But the researchers, whose work was published in…

The outbreak of the novel coronavirus has the world in its grip. Not since the Spanish flue outbreak of 1918 has a disease spread across the world so far and so fast. But how did we get here, and what have we learned? This is the story behind the virus called SARS-CoV-2 that has left a trail of infection touching everyone, everywhere. ...

One of the most frustrating symptoms of COVID-19 coronavirus is the loss of the sense of smell and scientists now say they think they understand why it happens. The experts writing in the journal Science Advances said the coronavirus infiltrates the cells that provide major structural support to sensory neurons -- the neurons that detect odors and send those messages to the brain. Since the sense of smell is linked to the sense of taste, the coronavirus also affects the ability to taste food. Harvard Medical School researchers said 90% of recovering COVID-19 patients who lost their sense of smell and taste regained it.   “Once the infection clears, olfactory neurons don’t appear to need to be replaced or rebuilt from scratch,” neurobiology professor Dr. Sandeep Robert Datta writes in the Science Advances study. “But we need more data and a better understanding of the underlying mechanisms to confirm this conclusion.”  In separate studies, scientists are still trying to conclude whether it is possible to get COVID-19 twice. They say the particular coronavirus that causes COVID-19 is new and much is…
