Amid coronavirus outbreak, Indian bans export of protective masks, clothing

India's COVID-19 tally raced past the seven lakh-mark with 22,252 fresh infections on Tuesday, five days after crossing the six lakh post, while the death toll climbed to 20,160 as 467 more people succumbed to the disease, according to the Union health ministry.

With this, the country has recorded over 20,000 cases of the infection for the fifth consecutive day.

India's coronavirus infection caseload stands at 7,19,665, the ministry's data updated at 8 am showed.

With a steady rise, the number of recoveries stands at 4,39,947, while there are 2,59,557 active cases of coronavirus infection in the country.

"Thus, around 61.13 % of patients have recovered so far," an official said.

The total number of confirmed cases also includes foreigners.

Of the 467 deaths reported in the last 24 hours, 204 are from Maharashtra, 61 from Tamil Nadu, 48 from Delhi, 29 from Karnataka, 24 from Uttar Pradesh, 22 from West Bengal, 17 from Gujarat.

Telangana and Haryana reported 11 deaths each; Madhya Pradesh nine; Andhra Pradesh seven; Jammu and Kashmir six; Rajasthan and Punjab five each; Bihar, Kerala and Odisha two each; and Arunachal Pradesh and Jharkhand one each.

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

Jan 17: India's "high power" communication satellite GSAT-30 was successfully launched in the early hours of January 17, the Indian Space Research Organisation (ISRO) said.

The satellite, aimed at providing high-quality television, telecommunications and broadcasting services, was launched onboard Ariane 5 rocket from French Guiana.

Blasting off from the Ariane Launch Complex in Kourou, a French territory located in northeastern coast of South America at 2.35 am IST, European space consortium Arianespace's Ariane 5 vehicle injected GSAT-30 into the orbit in a flawless flight lasting about 38 minutes.

Arianespace CEO Stéphane Israël tweeted about the successful launch of GSAT-30.

ISRO's U R Rao Satellite Centre Director P Kunhikrishnan, who was present in Kourou, congratulated the ISRO community and Arianespace team on the successful launch.

Calling it an "excellent start" to 2020 for ISRO with the launch, he said, "The mission team at the master control facility have already acquired the satellite and they will immediately complete the post launch operations...."

The 3,357-kg satellite, which was deployed from the lower passenger position of Ariane-5 launch vehicle (VA 251) into to geostationary transfer orbit (GTO), is configured on ISRO's enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands.

The satellite derives its heritage from ISRO's earlier INSAT/GSAT satellite series, and is equipped with 12 C and 12 Ku band transponders.

GSAT-30 is to serve as replacement to the "aging" INSAT-4A spacecraft services with enhanced coverage, ISRO has said, adding the satellite provides Indian mainland and islands coverage in Ku-band and extended coverage in C-band covering Gulf countries, a large number of Asian countries and Australia.

With a mission life of 15 years, GSAT-30 is an operational communication satellite for DTH, television uplink and VSAT services.

The Bengaluru-headquartered ISRO has said the communication payload of GSAT-30 is specifically designed and optimised to maximise the number of transponders on the spacecraft bus.

According to the space agency, the spacecraft would be extensively used for supporting VSAT (Very Small Aperture Terminal) network, television uplinking and teleport services, digital satellite news gathering (DSNG), DTH television services, cellular backhaul connectivity and many such applications.

One Ku-band beacon downlink signal is transmitted for ground-tracking purpose, it added.

For its initial flight of 2020, Arianespace on its website said, it would orbit EUTELSAT KONNECT, a telecommunication satellite for the operator Eutelsat, along with GSAT-30, using an Ariane 5 launch vehicle from the Guiana Space Centre.

EUTELSAT KONNECT – which was produced by Thales Alenia Space for Eutelsat – was riding in the upper position of Ariane 5's payload arrangement, and was released first in the flight sequence at 27 minutes following liftoff.

Since the launch of India's APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 24 satellites, including GSAT-30, for the Indian space agency.
