Coronavirus Test Kits Sent to States Are Flawed, C.D.C. Says Coronavirus Test Kits Sent to States Are Flawed, C.D.C. Says
(3 days later)
Some of the coronavirus testing kits sent to state laboratories around the country have flaws and do not work properly, the Centers for Disease Control and Prevention said on Wednesday.Some of the coronavirus testing kits sent to state laboratories around the country have flaws and do not work properly, the Centers for Disease Control and Prevention said on Wednesday.
The kits were meant to enable states to conduct their own testing and have results faster than they would by shipping samples to the C.D.C. in Atlanta. But the failure of the kits meant that states that encountered problems with the test should not use it, and would still have to depend on the C.D.C.’s central lab, which could cause several days’ delay in getting results.The kits were meant to enable states to conduct their own testing and have results faster than they would by shipping samples to the C.D.C. in Atlanta.

“Obviously, a state wouldn’t want to be doing this test and using it to make clinical decisions if it isn’t working as well, as perfectly, at the state as it is at C.D.C.,” Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said at a news conference on Wednesday.“Obviously, a state wouldn’t want to be doing this test and using it to make clinical decisions if it isn’t working as well, as perfectly, at the state as it is at C.D.C.,” Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said at a news conference on Wednesday.
The C.D.C. recommends testing for people who have symptoms like fever, cough or shortness of breath, and who, within the past 14 days, have traveled to China or have been in close contact with someone who is infected with the coronavirus. Doctors with patients in that category are supposed to consult their state health department about whether the individuals should be tested for the virus.The C.D.C. recommends testing for people who have symptoms like fever, cough or shortness of breath, and who, within the past 14 days, have traveled to China or have been in close contact with someone who is infected with the coronavirus.

The C.D.C. announced late Wednesday that another evacuee quarantined at a military base in California had tested positive for coronavirus. The latest individual who was diagnosed among the evacuees from Wuhan, the epicenter of the outbreak, brings the total of confirmed cases to 14 in the United States. A previous case was diagnosed at the Miramar base in San Diego on Sunday.The C.D.C. announced late Wednesday that another evacuee quarantined at a military base in California had tested positive for coronavirus.

The first and second patients arrived on different planes and were housed in separate facilities at Miramar, according to the C.D.C. Dr. Chris Braden, an expert on the site, said in a statement that “At this time there is no indication of person-to-person spread of this virus at the quarantine facility, but C.D.C. will carry out a thorough contact investigation as part of its current response strategy to detect and contain any cases of infection with this virus.”The first and second patients arrived on different planes and were housed in separate facilities at Miramar, according to the C.D.C.

The C.D.C. announced last week that it had begun shipping about 200 kits to laboratories in the United States and roughly 200 more to labs in more than 30 other countries. Each kit can test about 700 to 800 specimens from patients, the agency said.The C.D.C. announced last week that it had begun shipping about 200 kits to laboratories in the United States and roughly 200 more to labs in more than 30 other countries.

“The test is the only way you can definitely know you have the infection,” Dr. Marrazzo said. “You absolutely need it for case counting. It allows you to know who’s infected. You can treat those people, if a treatment is available, and you can isolate them.”“The test is the only way you can definitely know you have the infection,” Dr. Marrazzo said. “You absolutely need it for case counting.

Doctors in China said there was an urgent need for a simpler, quicker diagnostic test, officials from the World Health Organization said during a news briefing on Wednesday.Doctors in China said there was an urgent need for a simpler, quicker diagnostic test, officials from the World Health Organization said during a news briefing on Wednesday.
On trial runs in some states, the C.D.C. kits produced results that were “inconclusive,” Dr. Messonnier said. The tests did not involve samples from potential patients, but were part of the routine quality-control procedures that labs followed before using a test to make real diagnoses.On trial runs in some states, the C.D.C. kits produced results that were “inconclusive,” Dr. Messonnier said.

The problem appeared to come from one ingredient involved in the test, Dr. Messonnier said, adding that the C.D.C. would make a new supply of that ingredient to send to all of the laboratories. Officials did not say when the ingredient would be shipped, but said the process was being expedited and the material would be made available as soon as possible.The problem appeared to come from one ingredient involved in the test, Dr. Messonnier said, adding that the C.D.C. would make a new supply of that ingredient to send to all of the laboratories.

States that did not have trouble with the kits could keep using them, Kristen Nordlund, a spokeswoman for the C.D.C., said, adding that those states would still receive the newly made ingredient from the agency.States that did not have trouble with the kits could keep using them, Kristen Nordlund, a spokeswoman for the C.D.C., said, adding that those states would still receive the newly made ingredient from the agency.

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.
Mass protests against police brutality that have brought thousands of people onto the streets in cities across America are raising the specter of new coronavirus outbreaks, prompting political leaders, physicians and public health experts to warn that the crowds could cause a surge in cases. While many political leaders affirmed the right of protesters to express themselves, they urged the demonstrators to wear face masks and maintain social distancing, both to protect themselves and to prevent further community spread of the virus. Some infectious disease experts were reassured by the fact that the protests were held outdoors, saying the open air settings could mitigate the risk of transmission.Mass protests against police brutality that have brought thousands of people onto the streets in cities across America are raising the specter of new coronavirus outbreaks, prompting political leaders, physicians and public health experts to warn that the crowds could cause a surge in cases.

Exercise researchers and physicians have some blunt advice for those of us aiming to return to regular exercise now: Start slowly and then rev up your workouts, also slowly. American adults tended to be about 12 percent less active after the stay-at-home mandates began in March than they were in January. But there are steps you can take to ease your way back into regular exercise safely. First, “start at no more than 50 percent of the exercise you were doing before Covid,” says Dr. Monica Rho, the chief of musculoskeletal medicine at the Shirley Ryan AbilityLab in Chicago. Thread in some preparatory squats, too, she advises. “When you haven’t been exercising, you lose muscle mass.” Expect some muscle twinges after these preliminary, post-lockdown sessions, especially a day or two later. But sudden or increasing pain during exercise is a clarion call to stop and return home.Exercise researchers and physicians have some blunt advice for those of us aiming to return to regular exercise now: Start slowly and then rev up your workouts, also slowly.

States are reopening bit by bit. This means that more public spaces are available for use and more and more businesses are being allowed to open again. The federal government is largely leaving the decision up to states, and some state leaders are leaving the decision up to local authorities. Even if you aren’t being told to stay at home, it’s still a good idea to limit trips outside and your interaction with other people.States are reopening bit by bit.

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.

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.Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath.

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.

More than 40 million people — the equivalent of 1 in 4 U.S. workers — have filed for unemployment benefits since the pandemic took hold. One in five who were working in February reported losing a job or being furloughed in March or the beginning of April, data from a Federal Reserve survey released on May 14 showed, and that pain was highly concentrated among low earners. Fully 39 percent of former workers living in a household earning $40,000 or less lost work, compared with 13 percent in those making more than $100,000, a Fed official said.
Taking one’s temperature to look for signs of fever is not as easy as it sounds, as “normal” temperature numbers can vary, but generally, keep an eye out for a temperature of 100.5 degrees Fahrenheit or higher. If you don’t have a thermometer (they can be pricey these days), there are other ways to figure out if you have a fever, or are at risk of Covid-19 complications.Taking one’s temperature to look for signs of fever is not as easy as it sounds, as “normal” temperature numbers can vary, but generally, keep an eye out for a temperature of 100.5 degrees Fahrenheit or higher.

The C.D.C. has recommended that all Americans wear cloth masks if they go out in public. This is a shift in federal guidance reflecting new concerns that the coronavirus is being spread by infected people who have no symptoms. Until now, the C.D.C., like the W.H.O., has advised that ordinary people don’t need to wear masks unless they are sick and coughing. Part of the reason was to preserve medical-grade masks for health care workers who desperately need them at a time when they are in continuously short supply. Masks don’t replace hand washing and social distancing.The C.D.C. has recommended that all Americans wear cloth masks if they go out in public.

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.

If you’re sick and you think you’ve been exposed to the new coronavirus, the C.D.C. recommends that you call your healthcare provider and explain your symptoms and fears. They will decide if you need to be tested. Keep in mind that there’s a chance — because of a lack of testing kits or because you’re asymptomatic, for instance — you won’t be able to get tested.If you’re sick and you think you’ve been exposed to the new coronavirus, the C.D.C. recommends that you call your healthcare provider and explain your symptoms and fears.

The C.D.C. does not recommend testing for people who may have been exposed to the virus but have no symptoms. Even if they are infected, if they are still in the incubation period, there may not be enough virus in their bodies for the test to detect.The C.D.C. does not recommend testing for people who may have been exposed to the virus but have no symptoms.

The inability to detect very early infections is one reason for keeping planeloads of people from Wuhan in quarantine instead of just testing them and letting them go if the results are negative. A person could test negative and still be infected.The inability to detect very early infections is one reason for keeping planeloads of people from Wuhan in quarantine instead of just testing them and letting them go if the results are negative.

Because there is an unknown window of time between when a person becomes infected and when the test can find the virus, health officials have determined that a quarantine of two weeks — believed to be the incubation period of the illness — is the best way to make sure that people who may be infected do not transmit the virus to others.Because there is an unknown window of time between when a person becomes infected and when the test can find the virus, health officials have determined that a quarantine of two weeks — believed to be the incubation period of the illness — is the best way to make sure that people who may be infected do not transmit the virus to others.
Tests for other infectious diseases can also fail to detect some cases. A panel of tests used to screen for respiratory viruses when pneumonia is suspected can give negative results even if a patient is infected, Dr. Marrazzo said. So can rapid tests for flu and strep throat. Blood tests for H.I.V. can miss the diagnosis in people who were recently infected.Tests for other infectious diseases can also fail to detect some cases.
