Pentagon official cautions India over Russian arms deal

May 20: The novel coronavirus is behaving differently in patients in northeast China who have contracted it recently compared with early cases, indicating it is changing as it spreads, a prominent doctor said.

China, which has largely brought the virus under control, has found new clusters of infections in the northeastern border provinces of Jilin and Heilongjiang in recent weeks, raising concern about a second wave.

Qiu Haibo, an expert in critical care medicine who is part of a National Health Commission expert group, said the incubation period of the virus in patients in the northeast was longer than that of patients in Wuhan, the central city, where the virus emerged late last year.

"This causes a problem, as they don't have any symptoms. So when they gather with their families they don't care about this issue and we see family cluster infections," Qiu told state broadcaster CCTV in a programme broadcast late on Tuesday.

Patients in the northeastern clusters were also carrying the virus for longer than earlier cases in Wuhan, and they were taking longer to recover, as defined by a negative nucleic acid test, he said.

Patients in the northeast also rarely exhibited fever and tended to suffer damage to the lungs rather than across multiple organs, he said.

He said the virus found in the northeastern clusters was probably imported from abroad, which could account for the differences.

He did not say where he though they might have come from but both Jilin and Heilongjiang border Russia.

China reported five new coronavirus cases on Wednesday, down from six a day earlier.

Four of the new cases were local transmissions and one was imported by a traveller coming from abroad, the commission said in a statement, compared with three imported cases reported the previous day.

China's total number of coronavirus infections stands at 82,965, while the death toll 4,634. 

Washington, Jul 1: The United States has approved four coronavirus vaccine candidates for clinical trials, Food and Drug Administration (FDA) head Stephen Hahn told reporters.

"Four vaccines have been approved for moving into clinical trials... and another six are in the pipeline for us to review," Hahn said during a press briefing on Tuesday.

The US Administration launched in May Operation Warp Speed, a joint project of Health and Defense Departments, which aims to deliver 300 million doses of a vaccine for COVID-19 by January 2021.

The country's top pandemics expert Anthony Fauci warned on Tuesday, however, that there is no certainty the United States will be able to develop a vaccine against COVID-19 that works and will be safe.

Data on vaccine effectiveness, he added, may be available in the winter or early next year.

Washington, Jul 14: Florida on Sunday reported a record 15,300 new coronavirus cases, the most by any state in a single day even as the coronavirus cases in the country have surged to 3,363,056.

The Washington Post reported that the huge number was result of both increased testing and widespread community transmission. The numbers shattered previous highs of 11,694 reported by California last week and 11,571 reported by New York on April 15.

Natalie E. Dean, an assistant professor of biostatistics at the University of Florida wrote that with Florida largely open for business, he doesn't expect this surge to slow.

Nationally, the conversation over reopening has become increasingly fraught amid the newly soaring case numbers, with much of the debate centering on whether schools should open their doors in the fall, reported the Post.

The Health workers in California and Texas too are facing an influx of COVID-19 patients where officials reported seven day averages for new cases - 8,664 and 9060 respectively.

According to the report, Florida has reported nearly 70,000 cases in last week alone, the most of any state.

Even though the COVID-19 cases are surging, Florida Gov. Ron DeSantis has stuck to an aggressive reopening plan with state officials recently ordering schools to reopen five days a week in the new academic year.

The state is also set to hold the Republican National Convention next month in Jacksonville's VyStar Veterans Memorial Arena, an indoor facility that seats about 15,000, reported Washington Post.

Seven-day averages for new cases -- considered a more reliable indicator of the virus's impact than single-day totals -- hit new highs in Alabama, Florida, Mississippi, Montana, North Carolina, Oklahoma and Puerto Rico.
