Coronavirus: India temporarily suspends e-visa facility for people in China

New Delhi, Apr 15: As the world grapples with coronavirus, researchers have found the presence of a different kind of coronavirus -- bat coronavirus (BtCoV) --in two bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu, according to a study by the Indian Council of Medical Research (ICMR).

There is no evidence or research to claim that these bat coronaviruses can cause disease in humans, said Dr Pragya D Yadav, Scientist at the National Institute of Virology (NIV), Pune and also the first author of study.

The study has been published in the Indian Journal of Medical Research,

Twenty-five bats of Rousettus and Pteropus species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu were found positive for BtCoV in Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.

"These bat coronaviruses have no relation with SARS-CoV2 responsible for the COVID-19 pandemic," Yadav said, adding that Pteropus bat species were earlier found positive for Nipah virus in 2018 and 2019 in Kerala.

"Bats are considered to be the natural reservoir for many viruses, of which some are potential human pathogens. In India, an association of Pteropus medius bats with the Nipah virus was reported in the past. It is suspected that the recently emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also has its association with bats," the objective of the study titled 'Detection of coronaviruses in Pteropus and Rousettus species of bats from different states of India' stated.

"In the present scenario of changing demography and ecological manipulations, it is challenging to have checks on the encounters of bats with other animals and humans," the study stated, highlighting that the need for active and continuous surveillance remains crucial for outbreak alerts for bat-associated viral agents with epidemic potential, which would be helpful in timely interventions.

"Although CoVs in the subfamily coronavirinae do not usually produce clinical symptoms in their natural hosts (bats), accidental transmission of these viruses to humans and other animals may result in respiratory, enteric, hepatic or neurologic diseases of variable severity. It is still not understood as to why only certain CoVs can infect people," the study said.

The scientists stressed on the need of proactive surveillance of zoonotic infections in bats.

The detection and identification of such viruses from bats also recommends cross-sectional antibody surveys (human and domestic animals) in localities where the viruses have been detected.

Similarly, if the epidemiological situation demands, evidence-based surveillance should also be conducted, the study said while emphasing on the need of developing strong mechanisms for working jointly with various stakeholders such as wildlife, poultry, animal husbandry and human health departments.

"In conclusion, our study showed detection of bat CoVs in two species of Indian bats. Continuous active surveillance is required to identify the emerging novel viruses with epidemic potential," Dr Yadav said.

Elaborating on the study, Dr Yadav said throat and rectal swab samples of two bat species -- Rousettus and Pteropus -- from seven states were screened for the bat coronvirus during which the representative samples collected from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu tested positive while those from Karnataka, Chandigarh, Punjab, Telengana, Gujarat and Odisha came out negative.

The reverse-transcription polymerase chain reaction (RT-PCR) tests and sequencing were used for the confirmation of the findings.

"This is an ongoing study to understand the prevalence of the Nipah virus in bats," she said.

United Nations, Jun 30: India accounts for 45.8 million of the world's 142.6 million "missing females" over the past 50 years, a report by the United Nations said on Tuesday, noting that the country along with China form the majority of such women globally.

The State of World Population 2020 report released on Tuesday by the United Nations Population Fund (UNFPA), the world organisation's sexual and reproductive health agency, said that the number of missing women has more than doubled over the past 50 years - from 61 million in 1970 to a cumulative 142.6 million in 2020.

Of this global figure, India accounted for 45.8 million missing females as of 2020 and China accounted for 72.3 million.

Missing females are women missing from the population at given dates due to the cumulative effect of postnatal and prenatal sex selection in the past, the agency said.

Between 2013 and 2017, about 460,000 girls in India were missing' at birth each year. According to one analysis, gender-biased sex selection accounts for about two-thirds of the total missing girls, and post-birth female mortality accounts for about one-third, the report said.

Citing data by experts, it said that China and India together account for about 90-95 per cent of the estimated 1.2 million to 1.5 million missing female births annually worldwide due to gender-biased (prenatal) sex selection.

The two countries also account for the largest number of births each year, it said.

The report cites data by Alkema, Leontine and others, 2014 National, Regional, and Global Sex Ratios of Infant, Child, and under-5 Mortality and Identification of Countries with Outlying Ratios: A Systematic Assessment' from The Lancet Global Health.

According to their analysis, India has the highest rate of excess female deaths, 13.5 per 1,000 female births, which suggests that an estimated one in nine deaths of females below the age of 5 may be attributed to postnatal sex selection.

The report notes that governments have also taken action to address the root causes of sex selection. India and Vietnam have included campaigns that target gender stereotypes to change attitudes and open the door to new norms and behaviours.

They spotlight the importance of daughters and highlight how girls and women have changed society for the better. Campaigns that celebrate women's progress and achievements may resonate more where daughter-only families can be shown to be prospering, it said.

The report said that successful education-related interventions include the provision of cash transfers conditional on school attendance; or support to cover the costs of school fees, books, uniforms and supplies, taking note of successful cash-transfer initiatives such as Apni Beti Apna Dhan' in India.

It said that preference for a male child manifested in sex selection has led to dramatic, long-term shifts in the proportions of women and men in the populations of some countries.

This demographic imbalance will have an inevitable impact on marriage systems. In countries where marriage is nearly universal, many men may need to delay or forego marriage because they will be unable to find a spouse, the report said.

This so-called "marriage squeeze", where prospective grooms outnumber prospective brides, has already been observed in some countries and affects mostly young men from lower economic strata.

"At the same time, the marriage squeeze could result in more child marriages, the report said citing experts.

Some studies suggest that the marriage squeeze will peak in India in 2055. The proportion of men who are still single at the age of 50 is forecast to rise after 2050 in India to 10 per cent, it said.

The UN report said that every year, millions of girls globally are subjected to practices that harm them physically and emotionally, with the full knowledge and consent of their families, friends and communities.

At least 19 harmful practices, ranging from breast ironing to virginity testing, are considered human rights violations, according to the UNFPA report, which focuses on the three most prevalent ones: female genital mutilation, child marriage, and extreme bias against daughters in favour of sons.

Harmful practices against girls cause profound and lasting trauma, robbing them of their right to reach their full potential, says UNFPA Executive Director Dr. Natalia Kanem.

This year, an estimated 4.1 million girls will be subjected to female genital mutilation. Today, 33,000 girls under age 18 will be forced into marriages, usually to much older men and an extreme preference for sons over daughters in some countries has fuelled gender-biased sex selection or extreme neglect that leads to their death as children, resulting in the 140 million missing females.

The report said that ending child marriage and female genital mutilation worldwide is possible within 10 years by scaling up efforts to keep girls in school longer and teach them life skills and to engage men and boys in social change.

Investments totalling USD 3.4 billion a year through 2030 would end these two harmful practices and end the suffering of an estimated 84 million girls, it said.

A recent analysis revealed that if services and programmes remain shuttered for six months due to the COVID-19 pandemic, an additional 13 million girls may be forced into marriage and 2 million more girls may be subjected to female genital mutilation between now and 2030.

The pandemic both makes our job harder and more urgent as so many more girls are now at risk, Kanem said.

New Delhi, Jun 15: Average temperature of India experienced a rise of 0.7 degree Celsius, along with decline in rainfall, significant increase in frequency of very severe cyclonic storms and droughts in over a decade due to human activities, the Ministry of Earth Sciences in its research report said.

The contentions were made in a report issued by the ministry on the impact of climate change. It will be published by Union Minister Harsh Vardhan on June 19.

According to the report, "Since the middle of the twentieth century, India witnessed rise in temperature; decrease in monsoon; rise in extreme temperature and rainfall, droughts, and sea levels; and increase intensity of severe cyclones.

The report, prepared by researchers of the Centre for Climate Change Research, a cell under The Ministry's Indian Institute of Tropical Meteorology, Pune, further stated that there is compelling scientific evidence that human activities have influenced these changes in regional climate.

India's average temperature has risen by around 0.7 degrees Celsius during 1901-2018, it said, adding that the rise is largely on account of GHG-induced warming and partially offset by forcing due to anthropogenic aerosols.

It states that the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3-4 times by the end of the century.

In the 30-year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degree Celsius.

According to the report, by the end of the century, the temperatures of the warmest day and the coldest night are projected to rise by approximately 4.7 degrees Celsius and 5.5 degrees Celsius, respectively.

Alarmingly, sea surface temperature of the tropical Indian Ocean has also risen by one degrees Celsius on average during 1951-2015.

"The frequency of very severe cyclonic storms during the post-monsoon season has increased significantly (+1 event per decade) during the last two decades (2000-2018)," it added.

This came in the backdrop of Cyclone 'Amphan' and 'Nisarga' which made landfalls on May 20 and June 3 and killed several people, flattened villages, and destroyed farms.

"This is the first-ever climate change assessment report for India. This report will be very useful for policy makers, researchers, social scientists, economists, and students," said M. Rajeevan, secretary, the Ministry of Earth Sciences.

Besides this, the report also highlighted various other unnerving data on climate change in the country. Both the frequency and extent of droughts have increased significantly during 1951-2016.

The overall decrease of seasonal "summer monsoon rainfall" during the last 6-7 decades has led to an increased propensity for droughts over India.

"In particular, areas over central India, southwest coast, southern peninsula and north-eastern India have experienced more than 2 droughts per decade, on average, during this period. The area affected by drought has also increased by 1.3 per cent per decade over the same period."

The Hindu Kush Himalayas (HKH) also experienced a temperature rise of about 1.3 degree Celsius during 1951-2014.

Several areas of the Himalayas have experienced a declining trend in snowfall and also retreat of glaciers in recent decades. By the end of the twenty-first century, its annual mean surface temperature is projected to increase by about 5.2 degree Celsius.

The summer monsoon precipitation from June to September over India has also declined by around 6 per cent from 1951 to 2015, with notable decreases over the Indo-Gangetic Plains and the Western Ghats, the report further states.
