"I think everyone has done their best to prepare, and we will all arrive well rested for sure," said Rose . & # 39; But no one knows exactly where their tournament game is. While my game wasn't great the first few holes, I made a few putts, hit one just off the green on my first hole of the day, so I looked at my caddy and said, 'Welcome back.' # 39; & # 39;

Part of the players' free time was spent studying the 37-page guide with information on strict protocols for testing, disinfection and social distance. Players, caddies and tournament personnel all underwent tests for the corona virus before entering the court and will receive daily temperature checks and tracking questionnaires before entering the clubhouse.

Some of the biggest draws, such as the No. 1-ranked Rory McIlroy and No. 4-ranked Justin Thomas make their first colonial appearances. Others, such as Brooks Koepka in third place and Dustin Johnson in fifth place, only make their second and third appearances, respectively.

Johnson, who started at number 10, shot 34 on his nine front but was then offended three of the next five holes. Rust was visible on the difficult fifth hole. About 20 yards from the green, he chopped his chip into the bunker and searched for bogey. He finished with a 1-over 71.

"I was certainly a little bit rusty, nervous, but had a good lap, and finally let it slide there," said Phil Mickelson, the two-time colonial champion, who only made his second appearance here in the past 10 years. "But it was fun to compete again and hopefully I play better every round."

Does asymptomatic transmission of Covid-19 occur?

So far, the evidence seems to prove that this is the case. A much-cited article published in April suggests that people are most contagious about two days before the onset of coronavirus symptoms, and an estimated 44 percent of new infections were due to transmission by people who did not yet have symptoms. showed. Recently, a top World Health Organization expert said that transmission of the coronavirus by people who had no symptoms was "very rare," but she later withdrew that statement.

How does the blood group affect the coronavirus?

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

How many people have lost their jobs to coronavirus in the United States?

The unemployment rate fell to 13.3 percent in May, the Department of Labor said on June 5, an unexpected improvement in the country's job market as recruitments recovered faster than economists expected. Economists had predicted that the unemployment rate would rise to as much as 20 percent after it reached 14.7 percent in April, the highest since the government began keeping official statistics after World War II. But instead, the unemployment rate fell, with employers adding 2.5 million jobs, after more than 20 million were lost in April.

Will protests cause a second viral wave of coronavirus?

Massive protests against police brutality that have brought thousands of people to the streets of cities across America raise the specter of new coronavirus outbreaks, prompting political leaders, doctors and public health experts to warn the crowd in cases could cause a wave. . Many political leaders affirmed the right of protesters to express themselves, but urged protesters to wear face masks and maintain social distance, both to protect themselves and to prevent further spread of the virus to the community. Some infectious disease experts were reassured that protests were taking place outdoors, saying that the open air could reduce the risk of transmission.

How do we start training again without hurting ourselves after months of lockdown?

Exercise researchers and doctors have some blunt advice for those of us who want to return to regular exercise now: start slowly and boost your workouts, too slowly. U.S. adults were generally about 12 percent less active after home mandates started in March than in January. But there are steps you can take to safely return to regular exercise. First, & # 39; Start with no more than 50 percent of the exercise you did for Covid & # 39; says Dr. Monica Rho, chief of musculoskeletal medicine at the Shirley Ryan AbilityLab in Chicago. Also thread in some preparatory squats, she advises. "If you haven't trained, you lose muscle mass." Expect some twitching after these preparatory, post-lockdown sessions, especially a day or two later. But sudden or increasing pain during exercise is a clarion sound to stop and return home.

My state opens again. Is it safe to go out?

States are gradually opening up again. This means that more public spaces are available for use and more and more companies are allowed to open again. The federal government largely leaves the decision to the states, and some state leaders leave the decision to the local authorities. Even if you're not told to stay at home, it's still a good idea to limit outdoor travel and interact with other people.

What is the risk of catching coronavirus from a surface?

Touching contaminated objects and then infecting us with the germs is not typical of how the virus spreads. But it can happen. A number of studies on the flu, rhinovirus, coronavirus, and other microbes have shown that respiratory diseases, including the new coronavirus, can spread by touching contaminated surfaces, especially in places such as nurseries, offices, and hospitals. But a long series of events must take place to spread the disease that way. The best way to protect yourself from coronavirus – be it superficial transmission or close human contact – is still to socialize, wash your hands, not touch your face, and wear masks.

What are the symptoms of coronavirus?

Common symptoms are 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 blocked sinuses are less common. The C.D.C. has also added chills, muscle aches, sore throats, headaches and a new loss of taste or smell as symptoms to watch out for. Most people get sick five to seven days after exposure, but symptoms can appear in two days or even 14 days.

How can I protect myself while flying?

If air travel is unavoidable, there are some steps you can take to protect yourself. Most importantly, wash your hands often and never touch your face again. If possible, choose a window seat. A study from Emory University found that during the flu season, the safest place to sit on a plane is by a window, because people who sit by the window had less contact with potentially ill people. Disinfect hard surfaces. When you get to your seat and your hands are clean, use disinfectant wipes to clean the hard surfaces on your seat, such as the head and armrest, seat belt buckle, the remote control, the screen, the back pocket of the seat and the tray table . If the chair is hard and non-porous or leather or pleather, you can also wipe it off. (Using wipes on upholstered chairs can result in a wet chair and spreading germs rather than killing them.)

Do I have to wear a mask?

The C.D.C. has recommended that all Americans wear cloth masks when going out in public. This is a shift in federal guidelines that reflects new concerns that the coronavirus is being spread by infected people who have no symptoms. So far, the C.D.C., like the W.H.O., has advised that everyday people should not wear masks unless they are sick and coughing. Part of the reason was to keep medical grade masks for health professionals who need them badly at a time when they are constantly in short supply. Masks do not replace hand washing and social distance.

What should I do if I feel sick?

If you have been exposed to, or think you have, the coronavirus and have a fever or symptoms such as coughing or breathing difficulties, call a doctor. They should advise you on whether to be tested, how to be tested, and how to seek medical treatment without potentially infecting or exposing others.

Like most players, veteran Ryan Palmer spent much of the layoff playing at his home club, which happens to be Colonial. The Colleyville, Texas resident had the honor of hitting the first tee shot at number 1.

When Palmer & # 39; s group left at 6:50 am Central Time, the sun was just beginning to rise through the sky-high oak peeking. , and players made footprints in the dew. The only sounds came from birdsong and birdsong from players. The flags did not move in the still air.
