Risk of inflight spread of COVID-19 ‘very low’, says WHO

October 22, 2020405 Views

The risk of COVID-19 spreading on flights appears “very low” but cannot be ruled out, despite studies showing only a small number of cases, the World Health Organization (WHO) said. “In-flight transmission is possible but the risk appears to be very low, given the volume of travellers and the small number of case reports. The fact that transmission is not widely documented in the published literature does not, however, mean it does not happen,” the WHO said in a statement to Reuters. The characterisation of the risk echoes the findings of a U.S. Defense Department study that last week described the probability of catching the disease on airliners as “very low”. Some airlines have however used more robust language to describe the risk of onboard transmission. Southwest Airl...

A majority of destinations around the world (53%) have now started easing travel restrictions introduced in response to the COVID-19 pandemic. Though many remain cautious in view of the development of the pandemic, the seventh edition of the UNWTO “COVID-19 Related Travel Restrictions: A Global Review for Tourism” confirms the ongoing trend towards the gradual restart of tourism. Analysing restrictions up to 1 September, the research carried out by the United Nations specialized agency for tourism found that a total of 115 destinations (53% of all destinations worldwide) have eased travel restrictions, an increase of 28 since 19 July. Of these, two have lifted all restrictions, while the remaining 113 continue to have certain restrictive measures in place. UNWTO Secretary-Genera...

Snow trouts losing their habitat in Himalayan rivers

Snow trout, the iconic cold water fish species found in Himalayan rivers, would lose their habitat by 16 per cent in the next 30 years and by over 26 per cent by 2070, a new climate change study by the government’s Wildlife Institute of India has found. The study -- ‘Is There Always Space at The Top’-- was published in the ‘Ecological Indicators’, a journal of high international repute based at the Netherlands, on September 6. The study indicates that most of the lower altitude streams across the Himalayas would be rendered unsuitable for the existence of snow trout with the rise in temperatures. An ensemble of 72 statistical models across the Himalayas, the study -- authored by Wildlife Institute of India (WII) scientists Aashna Sharma, Vineet Kumar Dubey, Jeyaraj Antony Joh...

Kempty falls, George Everest in high landslide susceptible zones of Mussoorie

Like most hill townships, Mussoorie, the popular hill station in Uttarakhand, has witnessed several landslides, probably resulting from an increased spate of developmental activities. The increased disaster hazard has led scientists to map the landslide susceptibility of Mussoorie and surrounding areas, showing that 15 percent of the region is highly susceptible to landslides. Landslide is a normal geomorphic process that becomes hazardous when interfering with any development activity. It has been noted that more than 400 causalities occur in the Himalayan region every year due to this phenomenon. The frequency and magnitude of the landslides increase every year, particularly in the hilly townships. This demands the large scale landslide susceptibility, hazard, risk, and vulnerabi...

Himalayan Hot Springs contributing to global warming!

Carbon outflux from Earth’s interior to the exosphere through volcanic eruptions, fault zones, and geothermal systems contribute to the global carbon cycle that effects short and long term climate of the Earth. Himalaya hosts about 600 geothermal springs, commonly known as hot springs, having varied temperature and chemical conditions. Their role in regional and global climate, as well as the process of tectonic driven gas emission, needs to be considered while estimating emissions to the carbon cycle and thereby to global warming. Hot spring near Yamunotri Indian Himalayan geothermal field hosts about 340 geothermal springs in natural as well as artesian condition that eject hot waters and volatiles with varied temperature and chemical composition. These sites provide an opportunit...

As many as 77 new species of butterflies have been found in the ecologically sensitive forest of Matheran hill station near Mumbai during a study conducted there over the last eight years, according to the Bombay Natural History Society. With this, the total number of butterfly species in the Matheran forest has now gone up to 140, city-based Bombay Natural History Society (BNHS) scientist Mandar Sawant said. Matheran is spread over an area of 214.73 sq km and is located about 80 km from the Maharashtra capital. "The eight-year-long rigorous study undertaken by BNHS from 2011 to 2019 has resulted in the discovery of 77 new species of butterflies in Matheran," the non-governmental research organisation said in a statement. "After a span of 125 years, for the first time such a ...
