But despite this sudden change, the coronavirus is not finished. So far this week, 4,430 people have been reported dead since Sunday. Of this number, 1,036 deaths have been reported in the past 24 hours.
Officials fear that the numbers will increase significantly due to the protests, and urge participants to get tested for the coronavirus.
"Based on how the disease spreads, there is reason to expect new clusters and potentially new outbreaks to progress," said Dr. Jerome Adams, American general surgeon this week.
The virus does not mutate, but it is still dangerous
New discoveries on the coronavirus still make their appearance months later. Scientists who have studied the virus have discovered that it does not mutate as they had feared from the start. But that doesn't mean it's less dangerous, they said this week.
So far, the evidence does not show that the situation is getting worse or worse. But the complacency of people and governments could increase its spread, said Maria Van Kerkhove, epidemiologist specializing in diseases at the World Health Organization.
"Scientists are looking to see if there are changes in the virus? And since it is a coronavirus ... there are normal changes in this virus that one would expect over time" she said. "None of these changes to date indicate that the virus itself is changing in terms of its ability to transmit or cause more serious disease."
But she said the presence of the virus over time could cause some people to lower their guard.
"They can become lax in the measures necessary to control the spread of the virus, such as social distancing," she said. "It is very difficult to maintain all these measures and we must remain strong and vigilant."
Study finds new reaction in children
At the start of the epidemic, it was reported that coronavirus did not affect children as much.
But things are moving slowly, and a new study shows that a rare inflammatory syndrome in children initially compared to Kawasaki disease is a little different.
A high proportion of sick children with multisystem inflammatory syndrome, a disturbing complication of Covid-19, had gastrointestinal symptoms and were of African descent. These characteristics differ from those of classic Kawasaki disease, according to the study.
The study was part of a group of 21 children and adolescents in Paris who suffered from multisystem inflammatory syndrome. All the patients had gastrointestinal symptoms such as abdominal pain, vomiting and diarrhea, according to the study published in the medical journal BMJ this week.
And more than half - 57% - had at least one parent born in sub-Saharan Africa or the Caribbean islands.
"Although children are more likely to become very ill if they have other chronic illnesses, including obesity, it is important to note that children without chronic illness are also at risk," said Lawrence C. Kleinman, professor in the Department of Pediatrics at Rutgers. Robert Wood Johnson School of Medicine in New Jersey. "Parents must continue to take the virus seriously."
Vaccine may be available next year
The race to find a vaccine remains a priority. About 100 million doses may be available early next year, said Dr. Francis Collins, director of the National Institutes of Health.
"Maybe we will, if all goes well," Collins told CNN. The US Biomedical Advanced Research and Development Authority, which is part of the Department of Health and Human Services, funds research on five different experimental vaccines. "I am optimistic that at least one, maybe two, maybe three will show up as if we need to," he said. "We want to cover our bets with a number of different approaches, so it is very likely that at least one and perhaps more will work."
He said his main concern is that people are afraid of being vaccinated and that the government will have to assure them that it is safe.
Pepcid could relieve symptoms of coronavirus
A common over-the-counter medication used to treat heartburn may have relieved patients with coronavirus.
Ten patients with Covid-19 took famotidine, the active ingredient in Pepcid. In all 10 cases, their symptoms improved, according to a study released Thursday. None were hospitalized and all survived.
"All of the patients noticed rapid improvement in their condition within 24 to 48 hours of starting famotidine," said the study published in the medical journal Gut. "These results suggest that famotidine may affect the course of Covid-19."
A study co-author noted that this is a small group of patients. Despite this, Dr. Joseph Conigliaro, a doctor at Northwell Health in New York, said he was encouraged by the results and plans to conduct a larger study with outpatients on famotidine.
Major tourist attractions reopen
The economy has been a major victim of the coronavirus. As the recession continues, 1.9 million more workers applied for unemployment assistance last week.
More than a quarter of the workforce - 42.6 million people - have now claimed benefits since the pandemic began to ravage the US labor market.
To help keep the economy afloat, all states in the United States have reopened in stages. For example, in Pennsylvania, more than 80% of the state is in the process of reopening, and 16 other counties will ease restrictions on Friday, said Governor Tom Wolf.
In Las Vegas, people packed casinos on reopening day Thursday. Most casinos required employees to wear masks and also encouraged guests to do so, said CNN affiliate KTNV.
Universal Orlando will reopen to the public on Friday. Universal Studios Florida, Universal's Islands of Adventure and Universal's Volcano Bay will welcome guests, but with limited participation.
"This carefully managed reopening is accompanied by new strict health, safety and hygiene procedures. ... Everyone will have to follow CDC guidelines and recommendations from health officials, as well as health and safety policies. 'Universal Orlando,' the complex said in a statement.
