Almeida had just been recruited to St. Thomas’ Hospital in London, where she received a virus known as B814 from British scientists who were studying the common cold. The scientists, led by David Tyrrell, knew there was something different about the virus. Though volunteers infected with B814 didn’t get the sore throats typical of most head colds, they experienced unusual feelings of malaise. And the virus was neutralized by fat solvents, which meant that unlike the average cold virus, B814 had a lipid coating.Almeida had just been recruited to St. Thomas’ Hospital in London, where she received a virus known as B814 from British scientists who were studying the common cold.

Though he had been told she was “seemingly extending the range of the electron microscope to new limits,” Tyrrell wasn’t optimistic. It was generally believed that the electron microscope could detect virus only in purified, concentrated samples. These specimens were anything but.Though he had been told she was “seemingly extending the range of the electron microscope to new limits,” Tyrrell wasn’t optimistic.

Almeida, however, was confident, Tyrrell recalled in his book “Cold Wars: The Fight Against the Common Cold” (2002), written with Michael Fielder. “She claimed she would be able to find virus particles in our organ cultures with her new improved techniques,” he wrote. “It was worth a try.”Almeida, however, was confident, Tyrrell recalled in his book “Cold Wars: The Fight Against the Common Cold” (2002), written with Michael Fielder. “She claimed she would be able to find virus particles in our organ cultures with her new improved techniques,” he wrote. “It was worth a try.”
The results, he wrote, “exceeded all our hopes. She recognized all the known viruses, and her pictures revealed the structures beautifully.

The only remaining problem was figuring out what to call the new virus. Influenza-like sounded a bit feeble, Tyrrell wrote. The images of B814 revealed that the virus was surrounded by a kind of halo, like a solar corona. The coronavirus was born.The only remaining problem was figuring out what to call the new virus.

From her own unpublished research and the work of others, Almeida immediately recognized that B814 was related to the infectious bronchitis virus, which causes serious disease in chickens. But until the emergence of SARS in 2002 and now Covid-19, coronavirus was largely seen as posing little threat to people.From her own unpublished research and the work of others, Almeida immediately recognized that B814 was related to the infectious bronchitis virus, which causes serious disease in chickens.

“Not much was made of it,” said Kenneth McIntosh, a professor of pediatrics at Harvard Medical School, who, as an investigator at the National Institutes of Health, discovered another coronavirus around the same time Almeida did her research. “It was just the common cold. Not a big deal.”“Not much was made of it,” said Kenneth McIntosh, a professor of pediatrics at Harvard Medical School, who, as an investigator at the National Institutes of Health, discovered another coronavirus around the same time Almeida did her research. “It was just the common cold.

The move to Canada proved lucky. In the late 1950s, Almeida found greater opportunity there than in London for people without college degrees.The move to Canada proved lucky. In the late 1950s, Almeida found greater opportunity there than in London for people without college degrees.
She found work as an electron microscopy technician at the Ontario Cancer Institute (now Princess Margaret Cancer Centre), a new research center in Toronto. There she mastered a technique called negative staining, in which a heavy metal, typically phosphotungstic acid, was used to heighten the contrast in the images. She would use this method to detect the coronavirus.She found work as an electron microscopy technician at the Ontario Cancer Institute (now Princess Margaret Cancer Centre), a new research center in Toronto.

In the 1960s, detecting virus in tissue samples was painstaking work. Samples were often cluttered with cellular debris, and virus particles were few and far between. Examining a single sample could take hours.In the 1960s, detecting virus in tissue samples was painstaking work.

“It took attention to detail, not just with the eyes, but preparing the materials, everything had to be exactly right,” McIntosh said in a telephone interview. “Attention to detail, patience and persistence. June Almeida had those qualities in spades.”“It took attention to detail, not just with the eyes, but preparing the materials, everything had to be exactly right,” McIntosh said in a telephone interview. “Attention to detail, patience and persistence.

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.
One reward for her effort was the chance to see something no human had ever seen. Conveying a sense of wonder, she began a 1963 journal article about the symmetrical structure of viruses with an ode to electron microscopy — and an apology to the poet William Blake.One reward for her effort was the chance to see something no human had ever seen.

By then many textbook chapters and virology articles featured the finely detailed images she produced. She was also better known for her other accomplishments, including capturing the first image of the rubella virus and identifying the structure of the virus that causes hepatitis B.By then many textbook chapters and virology articles featured the finely detailed images she produced.

Almeida passed her methods on to other virologists, who used them to make important discoveries. Among those she trained was Albert Kapikian, who used immune electron microscopy at the National Institutes of Health to discover the norovirus, a stomach bug that accounts for about half of all food-borne illness.Almeida passed her methods on to other virologists, who used them to make important discoveries.
