Narendra Modi, BJP MPs to observe fast to protest budget session washout

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.

New Delhi, Jun 24: A litre of diesel on Wednesday was more expensive than a litre of petrol after the price of the former was hiked by 48 paise on the 18th successive day of fuel price revisions. While petrol price remained unchanged for the first time since June 7, diesel prices maintained upward trajectory to touch new highs.

It is for the first time in Delhi that diesel has become more expensive than petrol. A litre of the fuel now costs ₹79.88 as against ₹79.76 for a litre of petrol, as per a report in news agency ANI.

While surging fuel prices may generate much-needed revenue for governments, it would also have a detrimental impact on household budgets. The spike in diesel prices also has a wider impact on the transport and agricultural sectors which are largely dependent on the fuel.

The widest gap between the prices of the two fuels was on June 18 of 2012 when a litre of petrol was at ₹71.16 in Delhi while diesel was at ₹40.91. On June 28, the gap between the two fuels was 31.17 per litre in Mumbai. Around that time, there was a spurt in sales of diesel passenger vehicles while demand for such vehicles has come down significantly in current times. This has also led many manufacturers to ditch diesel engines completely.

The current trend of fuel price hikes are unlikely to do demand for petrol vehicles much good either.

Daily price revisions of the two fuel had been temporarily halted for 83 days till it was resumed on June 7.

India's demand for fuel doubled in May and has been steadily rising in June with the easing of restrictions. Indian refineries have already scaled up crude processing with Indian Oil Corp, the country's top refiner, looking to operate its plants at about 90% capacity in June.

The rising fuel prices, however, have resulted in political uproar with Congress leading the charge against the central government and accusing it of penalising consumers by imposing high taxes. A demand for including fuel prices under Goods and Services Tax (GST) has also been renewed by many but it is highly unlikely that it would happen. With oil companies looking to cut back on their previous loses and governments - central as well as states - aiming to generate revenue after tumultous weeks of lockdown, fuel price hikes are likely to stay till at least the end of June.

Beijing, Jan 21: The Chinese official investigating a pneumonia outbreak stemming from a new coronavirus said the disease can spread from person to person but can be halted with increased vigilance, as authorities on Tuesday confirmed a fourth death.

Zhong Nanshan said there was no danger of a repeat of the Severe Acute Respiratory Syndrome (SARS) epidemic that killed nearly 800 people globally during a 2002-2003 outbreak, which started in China, as long as precautions were taken.

"It took only two weeks to identify the novel coronavirus," state news agency Xinhua quoted Zhong as saying late on Monday.

The outbreak was still in its early stages and China had good surveillance and quarantine systems to help control it, he added.

The outbreak has spread from the central city of Wuhan to cities including Beijing and Shanghai, with more than 200 cases reported so far. Four cases have been reported outside China - in South Korea, Thailand and Japan.

Australia on Tuesday said it would screen passengers on flights from Wuhan amid rising concerns that the virus will spread globally as Chinese travellers take flights abroad for the Lunar New Year holiday starting this week.

Authorities around the globe, including in the United States and many Asian countries, have stepped up screening of travellers from Wuhan.

Chinese authorities confirmed a total of 217 cases of the virus in China as of 6 p.m. (1000 GMT) on Monday, state television reported, 198 of which were in Wuhan.

A fourth person died on Jan. 19, the Wuhan Municipal Health Commission said. The 89-year-old man, who had underlying health diseases including coronary heart disease, developed symptoms on Jan. 13 and was admitted to hospital five days later, it added.

Zhong, who is renowned in China for his work fighting SARS in 2003, confirmed that the virus can pass from person-to-person.

Fifteen medical workers in Wuhan had been diagnosed with pneumonia, with one other suspected case, the Wuhan Municipal Health Commission said. Of the infected staff, one was in critical condition.

In Shanghai, officials on Tuesday confirmed a second case involving a 35-year-man who had visited Wuhan in early January, and said they were monitoring four other suspected cases.

The virus causes a type of pneumonia and belongs to the same family of coronaviruses as SARS. Symptoms include fever and difficulty in breathing, which are similar to many other respiratory diseases and pose complications for screening efforts.

The World Health Organisation (WHO) said on Monday an animal source appeared most likely to be the primary origin of the outbreak and that some "limited human-to-human transmission" occurred between close contacts.

The Geneva-based U.N. agency convened an emergency committee for Wednesday to assess whether the outbreak constitutes an international health emergency and what measures should be taken to manage it.

So far, the WHO has not recommended trade or travel restrictions, but a panel of independent experts could do so or make other recommendations to limit spread.
