Coronavirus symptoms can stick around for weeks, even in otherwise healthy people who don't have a severe case of the virus, the US Centers for Disease Control and Prevention said in a grim new analysis.

The CDC surveyed 292 people who tested positive for the virus, and 35% said they still weren't back to their usual good health even two or three weeks after testing positive.

While older people were more likely to feel prolonged symptoms, even young adults without underlying conditions reported feeling unwell for a long period of time, the CDC said.

The new understanding into how the virus affects patients comes as more than 4.1 million cases of coronavirus cases and 145,539 deaths have been reported in the US, according to data from Johns Hopkins University.

On Friday, the United States recorded 73,715 new cases of Covid-19 and 1,130 deaths, according to information provided by Johns Hopkins University.

The US has now recorded a total of 4,112,531 coronavirus cases, of which at least 145,546 people have died. The totals include cases from all 50 states, the District of Columbia and other US territories, as well as repatriated cases. 

The three worst hit states, New York, California and Florida, have each recorded more than 400,000 cases. Texas has recorded over 380,000 cases and the next worst-hit state, New Jersey, has recorded more than 178,000 cases.

A 57-year-old man has tested positive for Covid-19 in Da Nang a city in central Vietnam according to a statement from the country's health ministry.

Prior to this infection being detected, Vietnam had recorded 100 days without a locally transmitted infection according to the state-run Vietnam News Agency (VNA).

The infected man had no international travel history, and had been living in Da Nang for the past month, the health ministry said. He presented with symptoms of fever and cough on July 20. After completing four health screenings, where he tested positive, the man was sent to Da Nang's disease control center for treatment and isolation.

Around 100 people who were close contacts of the man have been tested, the results of which have come back negative, the VNA report said.

More than 300 hospital workers have become infected with Covid-19 in the Australian state of Victoria, Premier Daniel Andrews said Saturday, as another 357 new cases of the virus were detected.

Five Victorians died as a result of the coronavirus Friday, the youngest in her 60s, Andrews said. Of the state's almost 4,000 active cases, 313 are health workers, and 536 are people in aged care settings, both staff and residents.

Andrews said the state faces significant challenges in keeping hospitals staffed and maintaining the safety of aged care residents.

The city of Melbourne and neighboring Mitchell Shire are under "Stage 3" restrictions, meaning residents can only leave their homes to buy food, go to work, exercise, or give and receive care.

Andrews said Saturday that a decision to mandate masks in public places is "essentially stage four" of the restrictions, adding "if they are worn by everybody then we may not need to go further."

Since the pandemic began, 7,744 cases of the coronavirus have been detected in Victoria, some 3,000 of which have since recovered.

Neighboring New South Wales, previously Australia’s worst hit state, recorded 15 new cases on Friday.

New Zealand Police have detained five people and charged four after they absconded from a managed isolation facility in the city of Hamilton, in the country's North Island, according to a statement from Assistant Commissioner Scott Fraser.  

Four of the five people have appeared in court on Saturday and been charged with breaching the Health Act notice, they have been granted bail and returned to isolation facilities. 

New Zealand Police said they committed a "considerable number of resources" -- including the deployment of an Eagle Helicopter -- in the effort to locate the people who escaped from the Distinction Hotel in Hamilton, which is being used to quarantine people who have recently returned from overseas and are required to complete mandatory two-week stay. 

More than 2,100 anti-Asian, pandemic-related hate incidents have been documented and submitted to Stop AAPI Hate, a reporting center founded by the Asian Pacific Policy and Planning Council since its launch in March.

Stop AAPI Hate has recorded incidents ranging from verbal harassment and physical assault to civil rights violations.

"This is not just a pandemic of health but a pandemic of hate that is attacking our AAPI communities around the country," said California Assembly member David Chiu during a Stop AAPI Hate news conference on July 1.

CNN previously reported that attacks on Asian people or people who appear to be East Asian have intensified after the coronavirus outbreak began in China.

Even the FBI has concerns. In April, in a letter to law enforcement officials, FBI Director Christopher Wray wrote that his agency remains "concerned about the potential for hate crimes by individuals and groups targeting minority populations in the United States who they believe are responsible for the spread of the virus.

South Korea’s Centers for Disease Control and Prevention (KCDC) reported 113 new virus cases on Saturday, the biggest jump in daily new cases since March 31. 

Among the 113 new cases, 86 are imported and 27 are locally transmitted, according to the KCDC. 

Local health officials had warned that 293 South Korean workers from Iraq who arrived on Friday would contribute to a surge in new numbers and so far, 36 of them have tested positive.

As of Saturday, 928 people are in quarantine in South Korea, the country's death-toll, meanwhile remains at 298. 

The new cases brings the country's tally of infections to 14,092, with 12,866 having recovered according to the KCDC.

At least one man has been hospitalized in Delaware after 12 people were inadvertently given incorrect Covid-19 test results, according to state officials. 

“In partnership with Walgreens, 2,791 samples were collected for processing through the Delaware Public Health Lab in the first week of testing. In the process of results delivery, 12 persons who tested positive for COVID-19 were inadvertently given negative results by phone due to an internal DPH system error,” a statement from the Delaware Department of Health said. 

The Health Department said that while incorrect results were given over the phone, the correct test results were reported into their surveillance system and were included in statewide testing numbers and the state’s contact tracing system. The state’s health department also said they wanted to assure the public that this was not an error that occurred on site at the Walgreens testing sites.

The first concern with a vaccine to prevent coronavirus infection will be safety, former Centers for Disease Control and Prevention director Dr. Thomas Frieden said Friday.

“This is the first time we've had an anti-vaccine movement before we've had the vaccine,” Frieden said in a podcast sponsored by the online news site Axios.

That makes it important to be honest and open with people about the risks, he said. 

One concern is a potential immune reaction to vaccination, he said. “Because some of the adverse outcomes from Covid-19 are immune-regulated, and that raises the theoretical concern that something like the Kawasaki-like illness that you're seeing in rare instances of childhood illness could be a rare adverse event of vaccination,” he said.

Frieden said if a coronavirus vaccine is approved, he’d get one. “If there’s enough vaccine enough to provide for essential workers and particularly health care workers first and it's demonstrated to be safe and effective, I'd be delighted to get vaccinated,” Frieden said.

“There are a lot of hurdles to get over before we actually have a vaccine available, proven to be effective, demonstrated to be safe and widely used,” he added. “First and foremost is safety and efficacy,” he said. “Does it work, how well, for whom, for how long and is it safe?”

So far 25 vaccines are in human trials around the world and 141 more are in preclinical trials, according to the World Health Organization.

But a vaccine will not be the only solution to the pandemic. “I think what we have to get past is the idea that there is one thing that’s going to make Covid go away,” Frieden said.
