Washington, Feb 18: The upcoming visit of President Donald Trump to India later this month has the potential to usher in a new era of bilateral ties between the two countries, a top American business advocacy group has said.

President Trump will pay a state visit to India on February 24 and 25 at the invitation of Prime Minister Narendra Modi. He would be accompanied by First Lady Melania Trump.

This would be the president's first bilateral visit in the third decade of the 21st century and also the first after his acquittal by the Senate in the impeachment trial.

"I believe President Trump's upcoming visit to India has the potential to usher in a new era of our bilateral ties," Mukesh Aghi, President of the US India Strategic and Partnership Forum (USISPF) said in a statement on Monday.

On the sidelines of the visit, the USISPF, in collaboration with the Federation of Indian Chambers of Commerce and Industry (FICCI) and the ORF, has announced to organise a program entitled "US-India Forum: Partners for Growth".

The full-day discussion will focus on the key pillars defining India and the US' strategic, economic, and cultural partnership over the next decade.

"We have an opportunity before us to make real progress on multiple aspects of the relationship— whether it is upholding peace and security in the Indo-Pacific region; building upon an already strong energy partnership; developing co-production and co-development opportunities in the defense space; or strengthening bilateral trade," Aghi said.

"We look forward to an extremely successful visit and some concrete outcomes from the visit," he said.

The day-long programme on February 25 in New Delhi, will bring together over 500 senior business executives, members of the US-India think tank community and leading figures of the Indian diaspora to set the agenda for this strategic partnership.

Discussions during the day will touch upon areas, including the Indo-Pacific Strategy and Maritime Security; the US-India Defence Partnership, the US-India Energy Partnership, Elevating US-India Trade and Investment and Role of the Indian Diaspora in US-India Relations.

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.
