What we're talking about today:Should we worry about a meat shortage?

Some good news:Don't feel pressure to exercise too much as you're stuck at home"Whatever your regular exercise routine was, I wouldn't alter it," one expert recommends.

California authorities pleaded for beachgoers to follow social distancing rules over the weekend after Gov. Gavin Newsom on Thursday temporarily shuttered Orange Countys coastline,a move he said was prompted by overcrowded beaches last weekend.

At least in some places, officials were pleased with results. In San Diego, where people can exercise on the beach but not linger, Mayor Kevin L. Faulconer praised residents for heeding safety restrictions that public health officials have credited at slowing the spread of the coronavirus.

But even as Newsom and others seek a cautious, phased reopening of the state, protesters dont want to wait.In Huntington Beach, police estimated 2,500 to 3,000 people gathered for May Day on a beachside street. They waved American flags and held signs. Most of them wore no masks and didnt practice social distancing.

In Sacramento, as police lined steps outside the Capitol, protesters waved signs that said Defend Freedom and broke into U-S-A chants.

A similar situation played out in various states on the East Coast on Saturday. New Jersey Gov. Phil Murphy said he was pleased with initial reports of social distancing from a beachfront park, state parks and some golf courses that also reopened on Saturday. Meanwhile aReopen Maryland rallydrew a large crowd addressed by Rep. Andy Harris.

More than 30 gravely ill patients who took part in an experimentaltreatment for COVID-19 at Houston Methodist Research Institute have recovered from the illness and have left the hospital, the physician overseeing the therapy said Friday.

"All of these people were very, very sick," Dr. James A. Musser, chairman of the department of pathology and genomic medicine at Houston Methodist Hospital, said in a phone interview. "Many of them were on ventilators. That was the common theme."

It cannot be said with certainty the treatment in which plasma donated by people who had fully recovered from the illness caused by the contagious and sometimes deadly coronavirus is injected into those still sick was responsible for recoveries, Musser said. But it appears to be a hopeful sign, he added.

Experts are still seeking to determine the types of patients who appeared to have benefited from the therapy and thetypes who did not.

In an effort to limit further coronavirus infections, New York is initiating an intensive projectto identify the population with antibodies and determine the source of new cases.

Newly admitted virus patients into hospitals a majority in the downstate region hover at about 900 daily on a three-day average, including 831 Friday.

In an effort to lower the rate, the state's Department of Health is collecting more detailed demographic data on incoming cases, identifying residence, age, gender, race, underlying conditions, occupation, commuting method and other data to determine patterns in the newly infected and other clues on how new cases are generated.

Gov. Andrew Cuomo says the aim is to determine if infections, for example, are spread through the homeor limited to front line workers.

In preliminary antibody testing of 15,000 people, up from 3,000 last week, one in five New York City residents tested positive for the virus antibody.

For Kentuckians and many across the horse racing industry, the first Saturday in May is a sacred holiday reserved for one thing: The Kentucky Derby.

Today would have marked the 146th running at Churchill Downs, which postponed the race until September due to the coronavirus pandemic. The event annually draws 150,000 people to the Louisville racetrack who come dressed in their best spring attire colorful hats, seersucker suits, linen pants and bow ties all to catch a glimpse of the fastest 2 minutes in sports, drink a Mint Julep and maybe spot a celebrity.

The last time the Derby wasn't held on the first Saturday in May was in 1945, when the U.S. government temporarily banned horse racing because of World War II.

And while racetracks in California, Kentucky and New York are closed,all eyes are on the Arkansas Derby at Oaklawn Park, which rescheduled its race for 3-year-olds fromApril 11 to May 2.

California has gained praisefor its speed in enactingsocial distancing orders which have helpedkeepthe most populousstate from suffering the kind of runaway outbreaks that have plagued other states. But a USA TODAY Network analysis finds the state is still woefully unprepared to reopenin accordance with public health recommendations.

Gov. Gavin Newsom recently laid out a reopening plan with benchmarks that must be met before he will recommend walking back stay-at-home orders and other social distancing measures.He called for California to test between 60,000 and 80,000 people daily.

California is doing just a third of that, as of late April, conducting only about 52 tests per 100,000 people each day, according to a USA TODAY Networkanalysis. Across the nation, Californiafalls slightly into the bottom half of all states.

California is far behind behind the national leaders Rhode Island, North Dakota and New Mexico which are respectively averaging about 260, 209 and 163 tests per 100,000 residents each day. No other states have yet to achievethe recommended testing metric, though New York and Massachusetts are close.

Newsom has saidsome business sectors, such as retail and manufacturing, may be able to open within weeks if the state's testing capability grows and case numbers slow. Butother businesses such as hair salons will take longer.Large gatherings such as concerts still remain out of reach, he said.

The FDAon Friday issued emergency authorization for use of remdesivir for the treatment of hospitalized coronavirus patients. Remdesivir"may be effective in treating COVID-19,"and "there is no adequate, approvedand available alternative,"the FDAs chief scientist Denise Hinton said in a letter.

Remdesivir is an experimental antiviral drug from the American biotech firm Gilead Sciences. It was originally tested as a treatment for Ebola and other coronaviruses including SARS and is now being tested as a possible COVID-19 treatment.

Early data from a global study released Wednesday found patients given remdesivir recovered faster and may be less likely to die. However, another study published the same day in the British medical journal The Lancet found no clinical benefits to the drug.
