If confirmed, the case of the fishmonger, Amirouche Hammar, would mean the deadly virus made an appearance on the continent long before officials there began tackling it. Such a discovery would bring a strange new wrinkle to the story of the virus in Europe, one that has the potential of blowing up the previously established chronology.If confirmed, the case of the fishmonger, Amirouche Hammar, would mean the deadly virus made an appearance on the continent long before officials there began tackling it.

The French government says it is looking at the report.

But if the timeline of when the virus appeared in Europe does change, the official efforts to combat the contagion will turn out to have been not just too late, but hopelessly too late.But if the timeline of when the virus appeared in Europe does change, the official efforts to combat the contagion will turn out to have been not just too late, but hopelessly too late.
By the time the first serious measures were put in place — the French government didn’t order a lockdown until March 16 — the virus may have already appeared three months earlier, according to a study of the new case that has been peer-reviewed and accepted for formal publication in the International Journal of Antimicrobial Agents.By the time the first serious measures were put in place — the French government didn’t order a lockdown until March 16 — the virus may have already appeared three months earlier, according to a study of the new case that has been peer-reviewed and accepted for formal publication in the International Journal of Antimicrobial Agents.
That, in turn, would help explain the rapidly developing catastrophe that has since unfurled in France and Europe. There have been thousands of cases, hospitalizations and deaths, in numbers that only in recent weeks have begun to abate somewhat, as a result of the French government’s rigid confinement measures.That, in turn, would help explain the rapidly developing catastrophe that has since unfurled in France and Europe.

“If confirmed, what this case does highlight is the speed at which an infection starting in a seemingly remote part of the world, can quickly seed infections elsewhere,” said Prof. Rowland Kao, the Sir Timothy O’Shea Professor of Veterinary Epidemiology and Data Science at the University of Edinburgh, in an interview for Britain’s Science Media Centre.“If confirmed, what this case does highlight is the speed at which an infection starting in a seemingly remote part of the world, can quickly seed infections elsewhere,” said Prof. Rowland Kao, the Sir Timothy O’Shea Professor of Veterinary Epidemiology and Data Science at the University of Edinburgh, in an interview for Britain’s Science Media Centre.

The journal publishing the report about the case has had a brush with controversy over the coronavirus, walking back a study it published about treatments for the virus.

But the authors of the paper, doctors at the Avicenne Hospital in the Paris suburb of Bobigny, among others, declare flatly: Their study is of a “patient infected with Covid-19 one month before the first reported cases in our country” whose “lack of recent travel suggests that the disease was already spreading among the French population at the end of December 2019.”But the authors of the paper, doctors at the Avicenne Hospital in the Paris suburb of Bobigny, among others, declare flatly: Their study is of a “patient infected with Covid-19 one month before the first reported cases in our country” whose “lack of recent travel suggests that the disease was already spreading among the French population at the end of December 2019.”
French authorities declared the first official cases of coronavirus in the country — three people who had all recently been in China — on Jan. 24.

What is not clear is how the patient, Mr. Hammar, got it. Apart from a trip to Algeria last summer, he had not traveled. His wife, however, briefly exhibited some of the symptoms — coughing, principally — of the coronavirus, Dr. Cohen said.What is not clear is how the patient, Mr. Hammar, got it.

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.
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.
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 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.
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.
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.
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.
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.
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 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.
The first case outside of China was reported in Thailand on Jan. 13. But experts have long suspected that the coronavirus may have spread internationally before the first officially reported cases.The first case outside of China was reported in Thailand on Jan. 13.

The detection of the potential new case in France follows similar instances in the United States, where officials recently discovered that deaths from the virus had occurred weeks earlier than previously known, and a model suggested that silent outbreaks had spread for weeks before detection.The detection of the potential new case in France follows similar instances in the United States, where officials recently discovered that deaths from the virus had occurred weeks earlier than previously known, and a model suggested that silent outbreaks had spread for weeks before detection.
