SC refuses to relax ban on crackers in NCR, rejects traders' plea

New Delhi, Jun 4: CSIR Director-General Shekhar Mande said on Thursday that the World Health Organisation's (WHO) decision to halt hydroxychloroquine (HCQ) drug trial was taken in haste and the global body should have actually analysed the data before making the decision.

"I firmly believe that WHO decision was taken in haste it was a kind of knee jerk reaction they should have actually analyse the data on their own before temporarily suspend the trials that is my personal opinion," Mande said.

India's nodal government agency ICMR (Indian Council of Medical Research) overseeing the country's response to the coronavirus pandemic last month wrote to the WHO citing differences in dosage standards between Indian and international trials that could explain the efficacy issues of HCQ in treating COVID-19 patients.

In addition, Dr Sheela Godbole, National Coordinator of the WHO-India Solidarity Trial and Head of the Division of Epidemiology, ICMR-National AIDS Research Institute also wrote a letter via an email to Dr Soumya Swaminathan, Chief Scientist at World Health Organisation.

In a letter, Dr Godbole stated: "There was no reason to suspend the trial for safety concern," attributing it to the current RECOVERY data which differs significantly from the non-randomised assessment by Mehra et al, a scientific paper.

Referring to the letter, the CSIR head said, "We don't know what actually happened behind the scenes but the hypothesis is that because of the paper published in Lancet. It is a very well known journal and if Lancet has done due vigilance in publishing the paper. 

Therefore, the WHO thought the paper's findings are right that's why WHO hold based on what is published on Lancet. The WHO shouldn't have accepted it immediately this should have taken their own due vigilance to find out that study is right or not."

DG CSIR said because there is a global outcry it must have put pressure on both Lancet as well as WHO and both of them now retracted from their original position. "WHO has started a trial again and Lancet has put an expression of concern on their website both of these are very welcome development for science," he said.

"So I am pretty sure that Lancet would have published the reports only after seeing somewhere the drug failed to work," Mande said.

New Delhi, Fevb 10: Of the countries most at risk of importing coronavirus cases, India ranks 17th, researchers have found on the basis of a mathematical model for the expected global spread of the virus that originated in China's Wuhan area in December 2019.

So far, India has reported three coronavirus positive cases -- all from Kerala.

Among the airports in India, the Indira Gandhi International Airport in New Delhi is most at risk, followed by airports in Mumbai, Kolkata, Bengaluru, Chennai, Hyderabad and Kochi, according to the model.

The new model for predicting global novel coronavirus cases has been developed by researchers from Humboldt University and Robert Koch Institute in Germany.

"The spread of the virus on an international scale is dominated by air travel," said the study.

"Wuhan, the seventh largest city in China with 11 million residents, was the relevant major domestic air transportation hub with many connecting international flights before the city was effectively quarantined on January 23, 2020, and the Wuhan airport was closed. By then the virus had already spread to other Chinese provinces as well as other countries," it added.

The researchers said that it is possible to estimate how likely it is that the virus spreads to other areas by looking at air travel passenger numbers.

"The busier a flight route, the more probable it is that an infected passenger travels this route. Using these probabilistic concepts, we calculate the relative import risk to other airports. When calculating the import risk, we also take into account connecting flights and travel routes that involve multiple destinations," said the study.

The top 10 countries and regions at risk of importing coronavirus cases are: Thailand, Japan, South Korea, Hong Kong, Taiwan, USA, Vietnam, Malaysia, Singapore and Cambodia, according to the model.

While Thailand's national import risk is 2.1%, it is 0.2% for India, found the research.

The foundation of the model is the worldwide air transportation network (WAN) that connects approximately 4,000 airports with more than 25,000 direct connections.

The model accounts for both, the current distribution of confirmed cases in mainland China as well as airport closures that were implemented as a mitigation strategy.

This network theoretic model is based on the concept of effective distance and is an extension of a model introduced in the 2013 paper "The Hidden Geometry of Complex, Network-Driven Contagion Phenomena" published in the journal Science.

The current outbreak of the 2019-nCoV virus started in Wuhan city, Hubei province, China. While the first cases were reported as early as December 8, 2019, the outbreak gained global attention on December 31, 2019, when the World Health Organization was alerted to "several cases of pneumonia" by an unknown virus.

The new virus was soon identified as a novel coronavirus and named 2019-nCOV. It belongs to the family of viruses that include the common cold and viruses such as SARS and MERS. On January 20, 2020, it was confirmed that the coronavirus can be transmitted between humans, greatly increasing the risk of a global spread.

The death toll due to the novel coronavirus outbreak in China has increased to 811 on Sunday, surpassing that of the Severe Acute Respiratory Syndrome (SARS) epidemic in 2003.

Although about 20 countries have confirmed cases, China has accounted for about 99 per cent of those infected. The first foreign victims of the virus both died on Saturday in Wuhan.
