  • The outbreak, initially identified in China, is continuing to grow.
  • The disease is called COVID-19. It’s caused by an infection with the new coronavirus, SARS-CoV-2, which is one of multiple coronaviruses that can be transmitted to humans.
  • Other examples of coronaviruses include SARS, MERS, and even the common cold.
  • The United States currently has the highest reported number of confirmed cases, with more than 1.7 million. However, due to a lack of testing, the number of actual cases may be far higher.
  • More than 102,000 people in the United States have died from the disease.

    published in the medical journal The Lancet found people with advanced cancer were nearly 5 times as likely to die after contracting COVID-19 than people without cancer, according to .

    Even for people whose cancer was relatively stable had double the risk of death if they contracted the disease.

    “The death rate for this group of patients as a whole was 13 [percent] more than twice that reported for all patients with COVID-19… Certain subgroups, such as patients with active (measurable) cancer and those with an impaired performance status, fared much, much worse,” said , MS, associate professor of medicine and biomedical informatics at Vanderbilt University, the study’s corresponding author in a statement.

    However, the team didn’t find that undergoing treatment for cancer, including chemotherapy or having surgery, impacted the risk of dying by COVID-19.

    They advised that these treatments shouldn’t be delayed due to the pandemic since it can cause worse outcomes for patients.

    Among their recommendations, the CDC advises companies to assess the building itself to make sure it has enough ventilation to prevent the virus from recirculating. Additionally, they advise separating workspaces and desks so people can maintain 6 feet of separation at all times.

    They point out that staggered start times, temperature checks, and disinfecting common space areas can also cut down on risk of transmission.

    Even with all these safeguards, the CDC recommends all workers wear face masks to protect themselves and others from aerosolized viral particles.

    体育投注网址 finds that COVID-19 was not being sustainably transmitted in the United States until weeks after the first case was detected. This means that cases weren’t spreading widely until mid-February.

    体育投注网址The report was released in a and hasn’t been peer reviewed. But it shows how delayed action by government officials may have worsened the COVID-19 outbreak in the United States.

    体育投注网址The first known U.S. case of COVID-19 was found to have occurred on Jan. 15. But that person was quarantined and their contacts also asked to quarantine.

    The study authors found that the start of sustained transmission of COVID-19 started in Washington state in mid-February after President Donald Trump had issued the travel ban for China.

    体育投注网址The United States stands out globally for having the most number of reported cases and deaths related to the virus. U.S. fatalities account for nearly a third of global deaths from COVID-19.

    体育投注网址While infections and deaths from COVID-19 have been trending downward, experts worry that there could be a second peak of infections and deaths as states reopen.

    体育投注网址The news of over 100,000 deaths from COVID-19 comes as virtually all states are loosening restrictions around shelter-in-place orders.

    体育投注网址The news came after the temporarily paused a study of hydroxychloroquine as a COVID-19 treatment over health concerns.

    Multiple studies have found no sign that the drug can help treat COVID-19. And research from last week found people on the drug were more likely to have abnormal heart rhythms and even die.

    The drug was originally designed as an antimalarial drug and has also been approved for use for autoimmune conditions such as lupus.

    体育投注网址The drug has made headlines as researchers investigated whether it could help treat people with COVID-19, and after President Donald Trump said he was taking the drug — even though experts cautioned there was no proof it would decrease the risk of COVID-19.

    Researchers, who published the study last week in 体育投注网址 medical journal, looked at more than 96,000 people hospitalized with COVID-19.

    体育投注网址Nearly 15,000 patients were given some form of medication that included either hydroxychloroquine or chloroquine, a similar drug.

    Not only did researchers not see evidence that the drug helped people with COVID-19, but patients on the medication were more likely to have abnormal heart rhythms and die.

    体育投注网址While many countries are tentatively starting to reopen businesses and allow gatherings, the WHO warned that the “first wave” of the virus is ongoing, which increases the risk of a “second peak” of cases.

    体育投注网址“We’re right in the middle of the first wave globally, if we look at the data from Central and South America… we’re still in the phase where the disease is on the way up,” said Mike Ryan, executive director, WHO Health Emergencies Programme.

    体育投注网址Ryan said that the number of people in each country who have contracted the virus is relatively low which means the virus could easily come back for a “second peak” if physical distancing, testing, and contact tracing measures aren’t implemented.

    This is different from a second wave which would mean the virus drops to very low levels for a number of months before returning with another surge later in the year.

    “We need to be cognizant that the disease could jump up at any time,” Ryan said. “We may get a second peak in this wave. This happened in pandemics in the past, it certainly happened in the pandemic of 1919.”

    体育投注网址In many countries, such as the United States, cases are declining but still at relatively high numbers, so there could be a second peak.

    Health officials are reporting that young adults, including people in their 20s, have developed symptoms of a rare syndrome now linked to COVID-19.

    体育投注网址Officials had initially only seen this rare syndrome called pediatric multisystem inflammatory syndrome (PMIS) in children. It appears to be similar to Kawasaki disease, which is characterized by inflamed blood vessels.

    体育投注网址Experts believe this new rare syndrome, where inflamed blood vessels cause symptoms including severe abdominal pain, rash, and difficulty breathing is related to COVID-19.

    One physician told the that young adults with the syndrome appear to have more severe cases than children.

    looks into the devastating impact of waiting to implement lockdowns when the virus first started to spread.

    体育投注网址Researchers from Columbia University looked at lockdown measures in the United States and the spread of the virus. While the nation was never completely locked down, widespread shelter-in-place orders started in mid-March.

    The preprint of the research reports that if wider lockdown measures had been implemented 2 weeks earlier on March 1 over 53,000 lives could have been saved.

    体育投注网址 surveyed healthcare workers across the country.

    体育投注网址Despite a major push to get personal protective equipment to doctors, nurses, and other key healthcare workers, many report a lack of basic equipment like face masks, hand sanitizer, and gloves.

    体育投注网址According to the poll, 8 in 10 workers had just one N95 mask for the entire shift. Additionally, over one third said they were running short of hand sanitizer and 40 percent said they were also running short on surgical masks that aren’t as protective as N95 masks.

    体育投注网址The poll was conducted from April 27 to May 4. Over 8,000 adults, 278 of whom worked in healthcare, were surveyed.

    Months after the COVID-19 pandemic led most U.S. states to issue some sort of shelter-in-place order, state governments are now loosening these restrictions.

    Researchers think antibodies from llamas may help them fight COVID-19.

    体育投注网址 published this week in the journal Cell found that antibodies taken from a llama were engineered to fight the new coronavirus. These special antibodies were effective in a lab setting at neutralizing the virus.

    The research is still in the early phases, but if successful it could mean that llama antibodies could help protect people from developing a severe case of COVID-19.

    体育投注网址, which is not yet published in a peer-reviewed journal, looked at 60,000 people with COVID-19 in addition to 47 children with the disease. The team found that children had just as much viral load or even higher amounts of viral load than some adults.

    This early research focusing on how children can spread the virus could be pivotal in helping officials combat a second wave as some states weigh loosening shelter-in-place orders.

    Another out of China found that school closures drastically helped lower transmission of the virus and lessen the severity of the outbreak.

    “While proactive school closures cannot interrupt transmission on their own, they can reduce peak incidence by 40-60 percent and delay the epidemic,” the authors said.

    Experts point out this is early research and more information is needed.

    “Are any of these studies definitive? The answer is ‘No, of course not,’” Jeffrey Shaman, an epidemiologist at Columbia University. But, he said, “to open schools because of some uninvestigated notion that children aren’t really involved in this, that would be a very foolish thing.”

    体育投注网址 finds that the novel coronavirus that causes COVID-19 was spreading around the world shortly after jumping from animal to humans in the last few months of 2019.

    The study looked at genetic data from 7,666 samples taken from people with COVID-19. By reviewing the genetic differences in the samples, the study authors concluded that the virus was able to spread quickly around the world at the end of 2019.

    Potentially it may have occurred in humans as early as October 2019.

    The “COVID pandemic started sometime around 6 October 2019 – 11 December 2019, which corresponds to the time of the host-jump into humans,” the authors wrote.

    体育投注网址The authors also found evidence that the virus is mutating, which is expected. But it wasn’t clear if those mutations were making the virus more contagious or deadly.

    On April 23, STAT News that a Chinese study failed to find any benefit using the drug. The Chinese 体育投注网址 included 237 people. Researchers administered the drug to 158 and compared their progress with the 79 who received a placebo.

    After a month, almost 14 percent of the people taking the drug had died compared with almost 13 percent of those receiving the placebo.

    The trial was stopped early partly because of side effects, which included “gastrointestinal symptoms (anorexia, nausea, and vomiting)” and worsened cardiopulmonary condition.

    “No statistically significant benefits were observed for remdesivir treatment beyond those of standard of care treatment,” study authors wrote.

    体育投注网址“We’re seeing this inflammatory response that we would normally see when someone was exposed to the cold temperature… like someone who has been playing outside with wet socks,” , a dermatologist at Massachusetts General Hospital in Boston, told . “However, in this setting, we’re seeing it in warm climates and we’re seeing it in patients who have been indoors and sheltering in place.”

    The two hospitals in Wuhan, China are at the center of the outbreak in that country. Researchers found evidence of aerosolized SARS-CoV-2 in the toilet area and in areas prone to crowding.

    The study has given more information about whether the virus is easily transmitted through the air. Researchers said proper ventilation and disinfection may help stop the virus from spreading in other similar areas.

    to detect COVID-19 antibodies.

    People who have COVID-19 antibodies have likely already had the disease and may have immunity against the virus in the future. Although it’s still too early to tell for certain.

    “Antibodies are only a part of the immune response to a virus. There are other viruses where antibody responses are clearly not associated with protection,” , a virologist at the David Geffen School of Medicine at UCLA told Healthline in an earlier interview.

    体育投注网址The test will cost $119 and people can order it without visiting a doctor. After ordering the test, you’ll have to go to a site in order to have your blood drawn.

    However, health experts disagree.

    They emphasize that the presence of antibodies indicates protection from future infection by the virus that causes COVID-19, but what’s unknown is how long that protection will last.

    Dr. , a professor in medicine at the University of East Anglia, told that everyone, or almost everyone, who recovers from COVID-19 “will have developed immunity, otherwise they would not have recovered.”

    体育投注网址He added, “What we do not know is how long that immunity will last. It almost certainly will not last for life.”

    体育投注网址The WHO walked back the controversial statement in a on April 25, admitting, “We expect that most people who are infected with #COVID19 will develop an antibody response that will provide some level of protection.”

    So far, the virus has spread to nearly 3 million people worldwide. However, many people don’t show symptoms, and recent suggest up to 80 percent of people with SARS-CoV-2 are “silent carriers.”

    Testing of in New York City revealed that “at this point in the pandemic in New York City, most of the patients who were positive for SARS-CoV-2 at delivery were asymptomatic.”

    Testing also revealed that “the true prevalence of infection may be underreported because of false-negative results of tests to detect SARS-CoV-2.”

    “Across New York City, we were seeing a large number of strokes and that these strokes were extremely concerning, and they were blocking big vessels to the brain,” , a Mount Sinai neurosurgeon, said in an .

    Reuters also reported that under a new protocol, higher doses of a blood thinner normally used to dissolve clots will be given to COVID-19 patients at Mount Sinai before any clots are detected.

    “We’re seeing clots everywhere, high rates of clots in veins of the legs. So, across the board, for sure, we all believe that — and there’s objective evidence that this disease increases clot formation,” Mocco said.

    The American Society of Hematology has noted COVID-19-associated clotting.

    Its to physicians states the benefits of blood-thinning therapy for those patients not already showing signs of clotting are “currently unknown.”

    looked at results for 184 patients with COVID-19 being treated in an ICU. Researchers found that 31 percent developed blood clots, a percentage they called “remarkably high.”

    The researchers theorized that patients are at high risk for these blood clots due to being immobilized in the ICU, a lack of oxygen, and high amounts of inflammation stemming from the infection.

    体育投注网址In an article in the , Dr. Harlan Krumholz, a cardiac specialist at the Yale-New Haven Hospital Center, said it’s unclear if the virus causes the blood clots by attacking the blood vessels, or if the immune system’s inflammatory response leads to the condition.

    “One of the theories is that once the body is so engaged in a fight against an invader, the body starts consuming the clotting factors, which can result in either blood clots or bleeding,” Krumholz told the Washington Post.

    “In Ebola, the balance was more toward bleeding. In COVID-19, it’s more blood clots,” he said.

    N95 masks are critical for healthcare workers treating people with COVID-19, but they’re in short supply. The new emergency use authorization could help protect healthcare workers that have been forced to ration or reuse masks.

    reports that governments worldwide are hoping the rapid tests — typically using a finger-prick of blood on a test strip — could soon “ease public restrictions by identifying people who have previously had the virus and have developed some immunity to it.”

    These tests are different from the used to detect whether someone actually has the virus in their body. Instead, they’re used to detect antibodies in the blood, which indicate whether someone has successfully beaten the infection.

    体育投注网址Government researchers how the virus has spread through the U.S. population are using antibody tests to guide pandemic response efforts.

    “This study will give us a clearer picture of the true magnitude of the COVID-19 pandemic in the United States by telling us how many people in different communities have been infected without knowing it, because they had a very mild, undocumented illness, or did not access testing while they were sick,” said , in a .

    “These crucial data will help us measure the impact of our public health efforts now and guide our COVID-19 response moving forward,” he said.

    found that the arrival of spring and summer weather likely won’t stop the spread of the virus.

    体育投注网址The study was published after a panel from the National Academies of Sciences reviewed data from around the world about the spread of SARS-CoV-2.

    Past pandemics such as the 1918 influenza outbreak have often waned dramatically in the summer with warmer temperatures and higher humidity helping to stop the spread of the virus, at least temporarily.

    However, officials say in this new report there’s no sign that changes in temperature nor humidity will have a big effect on COVID-19.

    体育投注网址In part, the panel found that because the virus is new and people don’t have natural immunity, they’ll be more susceptible to contracting the virus throughout the year.

    The panel did say more research would be needed and there’s a chance the viral spread may slow somewhat during the summer months even if it doesn’t stop.

    “There is some evidence to suggest that SARS-CoV-2 may transmit less efficiently in environments with higher ambient temperature and humidity,” the panel wrote, according to the . “However, given the lack of host immunity globally, this reduction in transmission efficiency may not lead to a significant reduction in disease spread.”

    The FDA will now allow gay and bisexual men to donate blood if they haven’t had sex with a man in the last 3 months. Previously, there was a ban on giving blood for men if they had sex with another man within the previous year.

    Prior to 2015, any man who had ever had sex with another man was banned from donating blood or plasma.


    According to the report, China “intentionally” reported false numbers about the extent of the COVID-19 outbreak.

    While the intelligence report itself hasn’t been revealed, certain government officials and experts say a lack of transparency about the actual data may have impacted how countries prepared for the COVID-19 outbreak.

    “The medical community made — interpreted the Chinese data as: This was serious, but smaller than anyone expected,” said Dr. Deborah Birx, who’s coordinating the White House response to the outbreak, according to Bloomberg News.

    “Because I think probably we were missing a significant amount of the data, now that what we see happened to Italy and see what happened to Spain,” she said.

    体育投注网址This comes one day after China reported that an additional 1,500 asymptomatic cases of COVID-19 hadn’t been counted in national totals.

    examined 9 people with SARS-CoV-2. The researchers wanted to understand (when the virus leaves its host) during illness to determine how infectious the disease may be.

    Conducted by German researchers, though not yet peer-reviewed, the findings suggest that viral shedding occurred in high levels from the throat during early phases of illness for the patients studied.

    However, the rate of shedding dropped after the fifth day in all patients except for two experiencing signs of pneumonia. They continued to shed COVID-19 at high levels until the 10th or 11th day, according to researchers.

    “The present study shows that COVID-19 can often present as a common cold-like illness. SARS-CoV-2 can actively replicate in the upper respiratory tract, and is shed for a prolonged time after symptoms end, including in stool,” the study authors .

    体育投注网址Scientists also found that people with COVID-19 may shed over 1,000 times more virus than emitted during peak shedding of the 2003 SARS infection. They say this could explain why COVID-19 has spread so rapidly.

    Public health experts have advised people to stop touching their faces to cut down on the risk of contracting the new coronavirus. But that’s easier said than done.

    Feb. 17 in Emerging Microbes & Infections finds evidence that there’s an oral-fecal transmission route.

    体育投注网址The scientists reported that viruses’ genetic material can be detected in both anal swabs and blood samples. Crucially, evidence of the new coronavirus was found in anal swabs and blood — even when it wasn’t detected using oral swabs.

    体育投注网址According to the study, this was particularly true for those patients receiving supportive care for several days.

    One of the most effective ways to prevent the spread of illnesses like COVID-19 or the flu is simple: Encourage employees to stay home when they’re sick.

    But since the United States doesn’t have a national paid sick leave policy, taking a sick day remains a financial sacrifice for who lack paid sick leave benefits.

    体育投注网址Without paid sick leave, workers are more likely to come into work sick, exposing their co-workers to an illness.
