Getty Images Plus The Missouri Christian summer camp Kanakuk, which is now in its 94th year of operation, likes to declare every year its “Best Summer Ever.” This year, that title will be tough to claim. Camp sessions opened on May 30 with an impressive roster of new safety measures in place, including new low-contact drop-off procedures, new air filtration systems, daily temperature checks, quarantine protocols, and more. But on June 26, the camp notified parents by email that there were two positive COVID-19 cases at K-2, one of its six camp locations. Over the next few days, the number of diagnoses climbed to 82. K-2 shut down, and parents from 10 states scrambled to pick up their children early. About 6.5 million young p...

LONDON (Reuters) - British scientists analysing data from a widely-used COVID-19 symptom-tracking app have found there are six distinct types of the disease, each distinguished by a cluster of symptoms. FILE PHOTO: A computer image created by Nexu Science Communication together with Trinity College in Dublin, shows a model structurally representative of a betacoronavirus which is the type of virus linked to COVID-19, better known as the coronavirus linked to the Wuhan outbreak, shared with Reuters on February 18, 2020. NEXU Science Communication/via REUTERS A King’s College London team found that the six types also correlated with levels of severity of infection, and with the likelihood of a patient needing help with breathing - such as oxygen or ventilator treatment - if they are h...

Fresh studies give more information about what treatments do or don’t work for COVID-19, with high-quality methods that give reliable results. British researchers on Friday published their research on the only drug shown to improve survival — a cheap steroid called dexamethasone. Two other studies found that the malaria drug hydroxychloroquine does not help people with only mild symptoms. Full coverage of the coronavirus outbreak For months before studies like these, learning what helps or harms has been undermined by “desperation science” as doctors and patients tried therapies on their own or through a host of studies not strong enough to give clear answers. “For the field to move forward and for patients’ outcomes to improve, there will need to be fewer small or inconclusive studies...

As the Covid-19 crisis escalates in the U.S., the scramble for an effective vaccine is about to collide with the electoral calendar. Pfizer (ticker: PFE) says it will seek Food and Drug Administration authorization for its Covid-19 vaccine as early as October. The federal government’s Covid-19 vaccine program, meanwhile, says it wants AstraZeneca’s (AZN) vaccine authorized by then. If either of these companies, or others in the vaccine race, such as Moderna (MRNA), deliver promising data from their large Phase 3 trials before the election, the result could be one of the most difficult decisions in the history of the FDA. A vaccine authorization before Nov. 3 could be a big political win for the Trump administration, which has made ...
