The drug maker Gilead Sciences is expanding its clinical trials of the antiviral drug remdesivir as a possible coronavirus treatment into several countries outside China, the company announced on Wednesday.The drug maker Gilead Sciences is expanding its clinical trials of the antiviral drug remdesivir as a possible coronavirus treatment into several countries outside China, the company announced on Wednesday.
Two new clinical trials of remdesivir are to begin in March, involving “approximately 1,000 patients at medical centers primarily across Asian countries, as well as other countries globally with high numbers of diagnosed cases,” Gilead said in a statement. It did not specify the countries where the trials will take place.Two new clinical trials of remdesivir are to begin in March, involving “approximately 1,000 patients at medical centers primarily across Asian countries, as well as other countries globally with high numbers of diagnosed cases,” Gilead said in a statement.

Remdesivir is already being tested in Wuhan, China, the center of the epidemic, and the United States National Institutes of Health announced on Tuesday that the drug would also be studied in some of the patients who contracted the illness overseas and were now being treated in Nebraska.Remdesivir is already being tested in Wuhan, China, the center of the epidemic, and the United States National Institutes of Health announced on Tuesday that the drug would also be studied in some of the patients who contracted the illness overseas and were now being treated in Nebraska.

The drug is still experimental, not yet approved to treat any disease. There are no approved treatments for illnesses caused by coronaviruses, including the new one, known as Covid-19. Studies of infected mice and monkeys have suggested that remdesivir can fight coronaviruses, and it appeared to cause few side effects when it was tested in patients with Ebola, although it did not work well against that virus.The drug is still experimental, not yet approved to treat any disease.

The experimental drug also stirred interest after doctors administered it to the first coronavirus patient in the United States. The man was hospitalized in Washington State, and his symptoms seemed to improve. But the experience of one patient cannot be used to determine whether any drug works.The experimental drug also stirred interest after doctors administered it to the first coronavirus patient in the United States.

Several companies are also working to develop a vaccine for the virus, which has spread around the globe. The number of cases now exceeds 80,980, and deaths total nearly 3,000.Several companies are also working to develop a vaccine for the virus, which has spread around the globe.

One of the companies, Moderna, said Monday it had delivered its experimental vaccine to the N.I.H. for early testing in humans, a record-setting pace. The nation’s top health officials have cautioned that development of a vaccine to treat large populations might take a year or more.One of the companies, Moderna, said Monday it had delivered its experimental vaccine to the N.I.H. for early testing in humans, a record-setting pace.

Researchers are trying to determine which patients remdesivir might help most, by giving the drug to people who are severely ill and also some who are not as sick. They also hope to find out how long a course of treatment is needed.Researchers are trying to determine which patients remdesivir might help most, by giving the drug to people who are severely ill and also some who are not as sick.

“Because it’s an outbreak and we try to target people who stand to have a clear benefit, first we target people who are symptomatic, so they are hospitalized,” Dr. Diana Brainard, Gilead’s senior vice president for H.I.V. and emerging viruses, said in an interview. “There is a precedent in respiratory viral infections, that the earlier you treat, the better, and there may be a threshold beyond which it doesn’t make sense to treat.”“Because it’s an outbreak and we try to target people who stand to have a clear benefit, first we target people who are symptomatic, so they are hospitalized,” Dr. Diana Brainard, Gilead’s senior vice president for H.I.V. and emerging viruses, said in an interview. “There is a precedent in respiratory viral infections, that the earlier you treat, the better, and there may be a threshold beyond which it doesn’t make sense to treat.”
On the other hand, she said, if the drug does help severely ill patients, that could be its greatest impact.On the other hand, she said, if the drug does help severely ill patients, that could be its greatest impact.
Another goal of the new trial is to find out if a shorter course of treatment will work. If a shorter duration does work, she said, “that automatically doubles the drug supply.” Faster treatment would also get patients out of the hospital faster, lessen their exposure to hospital-based infections and make room for more patients, she added.Another goal of the new trial is to find out if a shorter course of treatment will work.

“We are looking for ways we can help the world prepare as well as possible for what appears to be a pandemic at this point,” Dr. Brainard said.“We are looking for ways we can help the world prepare as well as possible for what appears to be a pandemic at this point,” Dr. Brainard said.

Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath. Some of these symptoms overlap with those of the flu, making detection difficult, but runny noses and stuffy sinuses are less common. The C.D.C. has also added chills, muscle pain, sore throat, headache and a new loss of the sense of taste or smell as symptoms to look out for. Most people fall ill five to seven days after exposure, but symptoms may appear in as few as two days or as many as 14 days.
Scientists around the country have tried to identify everyday materials that do a good job of filtering microscopic particles. In recent tests, HEPA furnace filters scored high, as did vacuum cleaner bags, fabric similar to flannel pajamas and those of 600-count pillowcases. Other materials tested included layered coffee filters and scarves and bandannas. These scored lower, but still captured a small percentage of particles.Scientists around the country have tried to identify everyday materials that do a good job of filtering microscopic particles.

A commentary published this month on the website of the British Journal of Sports Medicine points out that covering your face during exercise “comes with issues of potential breathing restriction and discomfort” and requires “balancing benefits versus possible adverse events.” Masks do alter exercise, says Cedric X. Bryant, the president and chief science officer of the American Council on Exercise, a nonprofit organization that funds exercise research and certifies fitness professionals. “In my personal experience,” he says, “heart rates are higher at the same relative intensity when you wear a mask.” Some people also could experience lightheadedness during familiar workouts while masked, says Len Kravitz, a professor of exercise science at the University of New Mexico.A commentary published this month on the website of the British Journal of Sports Medicine points out that covering your face during exercise “comes with issues of potential breathing restriction and discomfort” and requires “balancing benefits versus possible adverse events.” Masks do alter exercise, says Cedric X.

The steroid, dexamethasone, is the first treatment shown to reduce mortality in severely ill patients, according to scientists in Britain. The drug appears to reduce inflammation caused by the immune system, protecting the tissues. In the study, dexamethasone reduced deaths of patients on ventilators by one-third, and deaths of patients on oxygen by one-fifth.The steroid, dexamethasone, is the first treatment shown to reduce mortality in severely ill patients, according to scientists in Britain.

The coronavirus emergency relief package gives many American workers paid leave if they need to take time off because of the virus. It gives qualified workers two weeks of paid sick leave if they are ill, quarantined or seeking diagnosis or preventive care for coronavirus, or if they are caring for sick family members. It gives 12 weeks of paid leave to people caring for children whose schools are closed or whose child care provider is unavailable because of the coronavirus. It is the first time the United States has had widespread federally mandated paid leave, and includes people who don’t typically get such benefits, like part-time and gig economy workers. But the measure excludes at least half of private-sector workers, including those at the country’s largest employers, and gives small employers significant leeway to deny leave.The coronavirus emergency relief package gives many American workers paid leave if they need to take time off because of the virus.

So far, the evidence seems to show it does. A widely cited paper published in April suggests that people are most infectious about two days before the onset of coronavirus symptoms and estimated that 44 percent of new infections were a result of transmission from people who were not yet showing symptoms. Recently, a top expert at the World Health Organization stated that transmission of the coronavirus by people who did not have symptoms was “very rare,” but she later walked back that statement.So far, the evidence seems to show it does.

Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads. But it can happen. A number of studies of flu, rhinovirus, coronavirus and other microbes have shown that respiratory illnesses, including the new coronavirus, can spread by touching contaminated surfaces, particularly in places like day care centers, offices and hospitals. But a long chain of events has to happen for the disease to spread that way. The best way to protect yourself from coronavirus — whether it’s surface transmission or close human contact — is still social distancing, washing your hands, not touching your face and wearing masks.Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads.

A study by European scientists is the first to document a strong statistical link between genetic variations and Covid-19, the illness caused by the coronavirus. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.A study by European scientists is the first to document a strong statistical link between genetic variations and Covid-19, the illness caused by the coronavirus.

The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected. Economists had forecast the unemployment rate to increase to as much as 20 percent, after it hit 14.7 percent in April, which was the highest since the government began keeping official statistics after World War II. But the unemployment rate dipped instead, with employers adding 2.5 million jobs, after more than 20 million jobs were lost in April.The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected.

If air travel is unavoidable, there are some steps you can take to protect yourself. Most important: Wash your hands often, and stop touching your face. If possible, choose a window seat. A study from Emory University found that during flu season, the safest place to sit on a plane is by a window, as people sitting in window seats had less contact with potentially sick people. Disinfect hard surfaces. When you get to your seat and your hands are clean, use disinfecting wipes to clean the hard surfaces at your seat like the head and arm rest, the seatbelt buckle, the remote, screen, seat back pocket and the tray table. If the seat is hard and nonporous or leather or pleather, you can wipe that down, too. (Using wipes on upholstered seats could lead to a wet seat and spreading of germs rather than killing them.)If air travel is unavoidable, there are some steps you can take to protect yourself.

If you’ve been exposed to the coronavirus or think you have, and have a fever or symptoms like a cough or difficulty breathing, call a doctor. They should give you advice on whether you should be tested, how to get tested, and how to seek medical treatment without potentially infecting or exposing others.If you’ve been exposed to the coronavirus or think you have, and have a fever or symptoms like a cough or difficulty breathing, call a doctor.

The other trial will involve 600 moderately ill patients. Along with standard care — oxygen if needed, fluids, medicines for pain and fever — a third will receive the drug for five days, and a third for 10 days. The last third will receive standard care alone.The other trial will involve 600 moderately ill patients.
