Petrol, diesel prices likely shoot up over Rs 5 a litre

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.

Newsroom, May 5: Following the union government's nod, preparations are afoot to bring back Indian nationals stranded abroad from May 7 onwards.

According to sources, in the first phase from May 7- 14, the government would allow more than 60 “non-scheduled, commercial” flights to operate from about 12 countries to India to bring back 15,000 citizens. At least half of those flights will be from the Gulf region, including UAE, Qatar, Saudi Arabia, Bahrain, Kuwait and Oman, while the rest would bring passengers from the U.S., the U.K., Singapore, Malaysia, Philippines and Bangladesh.

The flights would be spread over 10 States identified as having the largest numbers to return, with Kerala, Tamil Nadu and Delhi (NCR) receiving the maximum number of flights.

A meeting held at the Ministry of Civil Aviation looked specifically at flights, mainly operated by Air India, while it awaits a final plan from countries where Indians need to be airlifted from. The first flights planned at present are from Abu Dhabi, Dubai, Riyadh and Doha, flying directly to Kozhikode and Kochi.

While the full estimate of Indians needing to return home could cross ten lakhs (a million), with more than two lakhs having registered to return from the UAE alone, officials said their return would be “prioritised and staggered”.

United Nations, May 21: At least 19 million children in parts of Bangladesh and India are at "imminent risk" from flash flooding and heavy rain as Cyclone Amphan makes landfall and the state of West Bengal is expected to take a direct hit from the powerful storm, the UN's children agency has warned.

The extremely severe cyclonic storm Amphan made a landfall at Digha in West Bengal and Bangladesh on Wednesday, leaving a trail of destruction. At least three persons were killed in India and seven in Bangladesh.

The UNICEF said that at least 19 million children in parts of Bangladesh and India are at “imminent risk from flash flooding, storm surges and heavy rain as Cyclone Amphan makes landfall.”

West Bengal, “home to more than 50 million people, including over 16 million children, is expected to take a direct hit from the powerful storm,” the UN agency said in a statement on Wednesday.

The UNICEF said it is also very concerned that the COVID-19 could deepen the humanitarian consequences of Cyclone Amphan in both the countries. Evacuees who have moved to crowded temporary shelters would be especially vulnerable to the spread of respiratory diseases like COVID-19, as well as other infections.

“We continue to monitor the situation closely,” said UNICEF Regional Director for South Asia Jean Gough.

“The safety of children and their families in the areas that will be impacted is a priority and it is good to see that the authorities have planned their urgent response factoring in the on-going COVID-19 pandemic.”

Across the region, the UNICEF is “working closely with the governments of Bangladesh and India and stands ready to support humanitarian operations to reach children and families affected by Cyclone Amphan.”

Based on the storm’s current trajectory, Cox’s Bazar in Bangladesh – now sheltering over 850,000 Rohingya refugees – is likely to experience high winds and heavy rains which may cause damage to homes and shelters in the refugee camps and Bangladeshi communities. This population is already highly vulnerable and cases of COVID-19 have recently been confirmed in the camps and host communities.

The UNICEF said it is working with the Deputy Commissioner’s Office in Cox’s Bazar, the Office of the Refugee Relief and Repatriation Commissioner, and humanitarian partners to help ensure Bangladeshi and Rohingya children and families remain protected.

These efforts include raising awareness among Rohingya and Bangladeshi communities on cyclone preparedness and prepositioning emergency life-saving water, sanitation, hygiene and medical supplies to meet immediate humanitarian needs.

Meanwhile, UN Secretary-General Antonio Guterres’ spokesperson Stephane Dujarric said at the daily press briefing that UN teams on the ground continue to work with the Government of Bangladesh to prepare and support those in need in the wake of the cyclone.

“Given the current pandemic, this support includes distributing personal protective equipment, disinfectants and other materials to evacuation shelters. To reduce the person-to-person contact during the delivery of aid, e-cash distributions will be used,” he said adding that the UN along with its partners is mobilising more than 1,700 mobile health teams and preparing for emergency food deliveries.

“The Super Cyclone is taking a westerly trajectory towards India, but nearly 8 million people in Bangladesh remain at risk,” he said adding that the Bangladesh government has evacuated more than 2 million people in high-risk areas.
