As many parts of the world gradually controlled Covid-19, the number of infections in the US soared again with many new hot spots.

Over the past 14 days, more than 20 states in the US have seen an increase in new cases of nCoV, the most serious of which is Texas, Florida, Arizona and California.

However, a high positive rate suggests that the promotion of testing is not the only reason for the numbers to skyrocket, because if the virus is contained, the number of positive cases will also decrease.

In Texas, after nearly three months of maintaining the number of new nCoV infections of about 1,000 - 2,000 a day, the numbers have skyrocketed over the past two weeks, with about 6,000 new infections a day, making Texas a new epidemic center.

Peter Hotez, director of the Vaccine Development Center at Children's Hospital of Texas, said that if this situation continues, Houston, the most populous city in the state, "will soon become the worst epidemic in the US".

Many people consider the main reason for the rise of Covid-19 in Texas is that the state is a pioneer in lifting the restrictive measures to prevent pandemic.

New developments forced Abbott last week to close all bars, while requiring restaurants to reduce productivity from 75 to 50%.

The crowded restaurants and bars seem to be the cause of a trend of pandemic across the United States.

Florida was also one of the states to begin the early blockade process, with home orders expiring shortly after Texas, on 4 May.

Beaches and recreation areas began to resume operations in late May, just in time for the anniversary of the Battle of the Dead, a federal holiday.

The number of hospitalizations also increased, but the number of deaths so far is not so serious.

"The three things people need to avoid are enclosed spaces with poor ventilation, crowded places and close contact," DeSantis stressed, urging young people to be more careful, avoid graduation parties and obey.

The Governor of Florida has stopped issuing mandatory measures to contain Covid-19.

The state of Arizona is the next "Covid-19" hot spot in the United States today and is rated as the place to record the most worrying increase.

Like Texas and Florida, reopening too early is thought to be the cause of the serious situation in Arizona.

As of June 30, the number of nCoV infections in Arizona increased 85% within 14 days, according to data from the Covid Exit Strategy expert group.

Native Americans account for just over 5% of the state's population, but account for 18% of deaths.

In addition to the number of cases, the rate of virus spread in Arizona has raised concerns among experts.

Arizona hospitals warn that intensive care units (ICUs) may soon be overloaded, as the number of patient beds already depleted, with 88% of ICU beds and 84% of regular patient beds being full, according to

After a series of criticism from health officials and Democrats, the Governor of the Republic of Ducey ordered the closure of bars, nightclubs, gyms, cinemas and water parks for at least 30 days, to "reduce the load."

Of the four states most affected by the Covid-19 recurrence, California was quite different.

However, two months after Gavin Newsom Governor announced that the Covid-19 curve on the graph "is believed to have been flattened, the number of new cases has risen sharply, to the highest level recorded in a single day."

Part of the reason is that increased social gatherings and family gatherings, especially among 18-49 year-old residents, account for the majority of nCoV-positive cases.

On June 28, seven counties in California, including Los Angeles, ordered the closure of bars.

Like many other locations across the country, California's major cities were the site of a massive protest movement against racist and police violence, after George Floyd, a black man.
