Syria-bound Russian military jet crashes with 92 onboard

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.

Jun 2: Pakistan's COVID-19 cases reached 76,398 on Tuesday after 3,938 new infections were reported across the country, while the death toll due to the coronavirus has gone up to 1,621, according to the health ministry.

The Ministry of National Health Services said that 78 COVID-19 deaths were recorded in the last 24 hours, taking the total number of fatalities in Pakistan to 1,621.

A total of 27, 110 people have recovered, it said.

Sindh has 29,647 patients, Punjab 27,850, Khyber-Pakhtunkhwa 10,485, Balochistan 4,514, Islamabad 2,893, Gilgit-Baltistan 738 and Pakistan-occupied Kashmir 271, it added.

The authorities have conducted 577,974 tests, including 16,548 in the last 24 hours.

The jump in the number of cases comes a day after Prime Minister Imran Khan said that people should learn to live with COVID-19 until a vaccine is developed.

Khan addressed the media after chairing the meeting of National Coordination Committee, the highest body to tackle the pandemic.

"Coronavirus will not go away until the vaccine is discovered. We need to learn to live with it and we can live with it if we follow precautions," he said.

He said the one million volunteers of the government's coronavirus force will raise awareness of the need to follow guidelines.

The government also said that all sectors will be opened slowly after deciding the negative list of businesses which will not be allowed.

Washington, Mar 28: A US-based lab has unveiled a portable test that can tell if someone has COVID-19 in as little as five minutes, it said in a statement Friday.

Abbot Laboratories said the US Food and Drug Administration (FDA) had given it emergency authorization to begin making the test available to healthcare providers as early as next week.

The test, which is the size of a small toaster and uses molecular technology, also shows negative results within 13 minutes, the company said in a press statement.

"The COVID-19 pandemic will be fought on multiple fronts, and a portable molecular test that offers results in minutes adds to the broad range of diagnostic solutions needed to combat this virus," said Abbot president and chief operating officer Robert Ford.

The test's small size means it can be deployed outside the "traditional four walls of a hospital in outbreak hotspots," Ford said, and Abbott is working with the FDA to send it to virus epicenters.

The test has not been cleared or approved by the FDA, and has only been authorized for emergency use by approved labs and healthcare providers, the company said.
