SC dismisses BJP leader’s PIL challenging minority status of Muslims, 4 other communities

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."

Mumbai, Mar 28: Doctors in Mumbai have not been spared by the novel coronavirus. As Mumbai’s count for Covid-19 cases went up to 58, an octogenarian doctor from Saifee Hospital passed away on Friday. He was a suspected case of coronavirus with co-morbid conditions like diabetes and had a pacemaker implanted, said a press release from the state health department.

As per a statement from Saifee Hospital, he underwent a CT scan at Saifee Hospital and was diagnosed positive for Covid-19. The surgeon was transferred to the special isolation facility at PD Hinduja Hospital where he subsequently died. Behranwala’s close relatives had come down from England and were under quarantine.

In a statement, Saifee Hospital, where Behranwala underwent CT scan, said, "All containment and surveillance measures have been implemented to ensure the safety of our staff patients and visitors. Saifee Hospital reiterates that the Hospital is fully operational," said Dr Vernon Desa, Director (Medical governance and clinical compliance) Saifee Hospital.

In the second case, an Andheri-based doctor, aged 53, has been tested positive along with his 43-year-old wife and 20-year-old daughter. The family doesn’t have a travel history. The doctor reportedly came in contact with the virus through a patient. MCGM has taken samples of 60 patients who came in contact with the doctor. "As of now, no patient from his contact has tested positive," Assistant Commissioner, Vishwas Mote.

Another doctor who practiced at Vakola tested positive after he came in contact with a person having travel history to Italy, later tested positive. The doctor has been admitted at Raheja hospital and samples of his close contact have been taken.
