Wuhan woman with no symptoms infects five relatives with coronavirus: Scientists

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.

Unnao, Feb 26: Ever heard of someone wishing a 'bright future' for the dead? In a bizarre incident in Uttar Pradesh's Unnao district, a village head issued a death certificate with the wish for an elderly man who had died last month.

The incident took place in the Sirwariya village in Asoha block where an elderly person Laxmi Shankar died after a prolonged illness on January 22.

His son went to the village head Babulal and requested him to issue a death certificate that he needed for some financial transactions.

Babulal not only issued the death certificate, but also 'wished' 'a bright future for the deceased' on the document.

The village head wrote in the death certificate -- "Main inke ujjwal bhavishya ki kaamna karta hoon (I wish him a bright future)."

The letter went viral on the social media on Monday after which the village head apologised for the error and issued a new death certificate.

The Kozhikode International Airport located at Karipur is not safe for the landing of flights in rainy season, according to an air-safety expert, who had warned the aviation ministry and the civil aviation regulator about this in 2011. 

The warning was particularly about the dangers of permitting passenger aircraft to land on runway 10 of the airport during rains and unfavourable wind conditions. 

Nine years later, on August 7, 2020, the warning became a reality when an Air India Express pilots landed in tailwind conditions and the aircraft overshot the tabletop runway to drop off the end and crash.

 “An aircraft landing on runway 10 in tailwind will experience poor braking action due to heavy rubber deposits … All such flights … are endangering the lives of all on board,’’ said Capt Mohan Ranganathan, in a letter sent on June 17, 2011 to then director general of civil aviation Bharat Bhushan and Nasim Zaidi, chairman of a civil aviation safety advisory committee, which was formed after the May 2010 Mangaluru air crash which killed 158 people.

“My warning issued after the Mangaluru crash was ignored. It is a table-top runway with a down slope. The buffer zone at the end of the runway is inadequate,” Capt Ranganathan said. Given the topography, he pointed out, the airport should have a buffer of 240m at the end of the runway, but it only has 90m (which the DGCA had approved). “Moreover, the space on either side of the runway is only 75m instead of the mandatory 100m,” he added.

Capt Ranganathan said there is no guideline for operations on a table-top runway when it is raining. “Runway 10 approach should not be permitted in view of the lack of runway end safety area (RESA) and the terrain beyond the end of the runway. RESA of 240m should be immediately introduced and runway length has to be reduced to make the operations safe,” his letter said.

If an aircraft is unable to stop within the runway, there is no RESA beyond the end. The ILS localiser antenna is housed on a concrete structure and the area beyond is a steep slope. “The Air India Express accident in Mangalore should have alerted AAI to make the runway conditions safe. We have brought up the issue of RESA during the initial Casac-sub group meetings. We had specifically mentioned that the declared distances for both runways have to be reduced in order to comply with ICAO Annex 14 requirement,” Capt Ranganathan said.

He said the condition of the runway strip was known to DGCA teams that have been conducting inspection and safety assessments. “Have they considered the danger involved? Did the DGCA or the airlines lay down any operational restrictions or special procedures?”

The letter also refers to Approach and Landing Accident Reduction (ALAR) training, which is supposed to be mandatory before every monsoon, but airlines don’t follow it, he said. “70% of accidents take place during approach and landing and that is why this training is essential,” he added.

Jakarta, Mar 15: Indonesia's transport minister is in intensive care after testing positive for the novel coronavirus, an official has said, as schools and tourist attractions were ordered to close over the health threat.

Transportation Minister Budi Karya Sumadi was receiving treatment at an army hospital in Jakarta, State Secretary Pratikno said on Saturday.

A hospital spokesman said Sumadi was encountering difficulty breathing but that his condition was improving.

Pratikno said Sumadi was involved in virus mitigation efforts, particularly the evacuation of Indonesians from epicenters of the outbreak, and that President Joko Widodo had called for tests to be carried out on other ministers.

Cases of the virus in Indonesia, the world's fourth most populous country, have jumped from zero two weeks ago to 96, with five deaths, according to government spokesperson Achmad Yurianto.

He also said the virus has spread outside Greater Jakarta to Bandung in West Java, Solo in Central Java, Manado in North Sulawesi, Pontianak in West Kalimantan, as well as holiday havens Yogyakarta and Bali.

Following the increase, the government on Saturday established a task force on COVID-19 mitigation.

Jakarta's Governor Anies Baswedan announced that schools would close for two weeks starting Monday, and ordered the closure of city-owned tourist attractions, such as Ragunan Zoo and Ancol beach.

He emphasized that Jakarta would not be locked down but urged people "to be responsible" and called for social distancing when possible.

Similarly, the administration of Solo, Central Java, Friday announced that schools and tourist attractions would close after a coronavirus patient died in the region.

The World Health Organization has said it is particularly concerned about high-risk nations with weaker health systems, which who may lack the facilities to identify cases.

A day after declaring the coronavirus outbreak to be pandemic this week, WHO chief Tedros Adhanom Ghebreyesus called Indonesia's president Widodo and both agreed to "scale up cooperation."
