The United States government has imposed a two-week federal quarantine on 195 people who were evacuated on Wednesday from Wuhan, China, to a California military base, the Centers for Disease Control and Prevention said on Friday.The United States government has imposed a two-week federal quarantine on 195 people who were evacuated on Wednesday from Wuhan, China, to a California military base, the Centers for Disease Control and Prevention said on Friday.
The action means that the group will be held at March Air Reserve Base in Riverside, Calif., to ensure they are not infected with the Wuhan coronavirus, which has sickened more than 9,800 people in China and killed more than 200. The 14-day period is dated from when their plane left Wuhan.The action means that the group will be held at March Air Reserve Base in Riverside, Calif., to ensure they are not infected with the Wuhan coronavirus, which has sickened more than 9,800 people in China and killed more than 200.

“While we recognize this is an unprecedented action, we are facing an unprecedented health threat,” Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said at a news conference on Friday.“While we recognize this is an unprecedented action, we are facing an unprecedented health threat,” Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said at a news conference on Friday.
A federal quarantine order in the United States is rare; the last one was imposed in the 1960s, but it was limited.A federal quarantine order in the United States is rare; the last one was imposed in the 1960s, but it was limited.
Dr. Messonnier called the federal order on Friday “science-based,” saying it was warranted because of the worsening epidemic in China. She cited the widening, rapid spread of the disease there, the increase in person-to-person transmission and the rising death toll. In addition, evidence has been emerging that people can transmit the disease even before they show symptoms of the illness, which can cause pneumonia in severe cases.Dr. Messonnier called the federal order on Friday “science-based,” saying it was warranted because of the worsening epidemic in China.

Another concern was that the passengers evacuated had been in Wuhan, the epicenter of the outbreak. At a news conference later on Friday, Alex M. Azar II, the secretary of health and human services, announced that other citizens of the United States who were returning from Hubei Province, which includes Wuhan, would also be quarantined for up to two weeks. Mr. Azar declared a public health emergency for the United States, and said foreign nationals who had been to China during the last 14 days would not be allowed into the United States.Another concern was that the passengers evacuated had been in Wuhan, the epicenter of the outbreak.

“This is a very serious public health situation, and the C.D.C. and federal government have and will continue to take aggressive action to protect the public,” Dr. Messonnier said. “If we take strong measures now, we may be able to blunt” the impact of the virus in the United States.“This is a very serious public health situation, and the C.D.C. and federal government have and will continue to take aggressive action to protect the public,” Dr. Messonnier said. “If we take strong measures now, we may be able to blunt” the impact of the virus in the United States.
Dr. Messonnier said that the people who were quarantined did not pose a threat to the surrounding community.Dr. Messonnier said that the people who were quarantined did not pose a threat to the surrounding community.
Since the 195 evacuees arrived in Riverside, they have had their noses and throats swabbed to test for the virus, and their temperatures taken several times a day. They were initially told that they would be detained for at least 72 hours, and possibly 14 days. Two weeks is thought to be the upper limit of the incubation period; if symptoms don’t start by then, a person can be cleared as not infected.Since the 195 evacuees arrived in Riverside, they have had their noses and throats swabbed to test for the virus, and their temperatures taken several times a day.

Not all the virus tests have been completed, but even if the results are negative, that does not mean a person is not infected, Dr. Messonnier said. It is possible to test too early for the virus, so a person who tests negative could still become ill and infect others. Therefore, officials said it was safer to detain people for the entire incubation period.Not all the virus tests have been completed, but even if the results are negative, that does not mean a person is not infected, Dr. Messonnier said.

Dr. Martin Cetron, director of the C.D.C.’s global migration and quarantine division, said the evacuees would benefit from the quarantine, which would prevent them from infecting their families and would provide close monitoring so that they could receive medical treatment quickly if symptoms developed.Dr. Martin Cetron, director of the C.D.C.’s global migration and quarantine division, said the evacuees would benefit from the quarantine, which would prevent them from infecting their families and would provide close monitoring so that they could receive medical treatment quickly if symptoms developed.
Citing quarantines in Toronto during the SARS outbreak there in 2003, he said that most people being quarantined accept it as “part of their civic responsibility to protect their community,” once they understand the reasons. He also said that many people flown home from Wuhan were diplomats who understood this as part of their duty.Citing quarantines in Toronto during the SARS outbreak there in 2003, he said that most people being quarantined accept it as “part of their civic responsibility to protect their community,” once they understand the reasons.

Until Friday, the evacuees’ detention at the air base had been unofficial. The group had stayed voluntarily for testing, except for one member, who tried to leave on Wednesday and was quarantined by Riverside County.Until Friday, the evacuees’ detention at the air base had been unofficial.

Federal law authorizes the C.D.C. to impose quarantines, but the power is rarely used. The last large-scale quarantine was imposed during the Spanish flu pandemic of 1918-19. The limited one in the 1960s that Dr. Cetron mentioned involved a possible case of smallpox.Federal law authorizes the C.D.C. to impose quarantines, but the power is rarely used.

Last week, China took the extreme measure of halting public transit and imposing a quarantine on Wuhan, a city of 11 million people. But people were already traveling extensively in and out of the country for celebrations of the Lunar New Year, prompting concerns that the virus would spread widely around the globe.Last week, China took the extreme measure of halting public transit and imposing a quarantine on Wuhan, a city of 11 million people.

So far, six people in the United States are known to be infected. Five had been to Wuhan and the sixth is the husband of one of those patients. He had not traveled to Wuhan, but contracted the illness from his wife after she returned home to Chicago. The other cases have been in Washington State, California and Arizona.So far, six people in the United States are known to be infected.

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.

Before he became ill, he had met with a Chinese business partner from his company near Munich, on Jan. 20 and 21. She was a resident of Shanghai who had been in Germany from Jan. 19 to 22. Though she was healthy during the visit, she got sick during her flight back to China, where she tested positive for the new coronavirus on Jan. 26. She informed her company, which traced her contacts to alert anyone she might have exposed.Before he became ill, he had met with a Chinese business partner from his company near Munich, on Jan. 20 and 21.
