No other government honoured Ambedkar as we did: PM Modi

New Delhi, Jul 21: The Centre has written to all states and union territories warning against the use of N-95 masks with valved respirator by people, saying these don't prevent the virus from spreading out and are "detrimental" to the measures adopted for its containment.

The Director-General of Health Services in the Ministry of Health, in a letter to the Principal Secretaries of health and medical education of states, said it has been observed that there is "inappropriate use" of N-95 masks, particularly those with valved respirator, by the public other than designated health workers.

The DGHS referred to the advisory on the use of homemade protective cover for face and mouth available on the website of the Ministry of Health.

"It is to bring to your knowledge that the use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it does not prevent the virus from escaping out of the mask. In view of the above, I request you to instruct all concerned to follow the use of face/mouth cover and prevent inappropriate use of N-95 masks," DGHS Rajiv Garg said in the letter.

The government had in April issued an advisory on the use of homemade protective cover for face and mouth, asking people to wear it, particularly when they step out of their residences.

The advisory stressed such face covers must be washed and cleaned each day, as instructed and states that any used cotton cloth can be used to make this face cover. 

The colour of the fabric does not matter but one must ensure that the fabric is washed well in boiling water for five minutes and dried well before making the face cover. Adding salt to this water is recommended, it said.

It also listed the procedures of making such homemade masks, asking to ensure it fits the face well and there are no gaps on the sides.

It urges people to wash hands thoroughly before wearing the face cover,  switching to another fresh one as the face cover becomes damp or humid, and never reusing it after single use without cleaning it. 

"Never share the face cover with anyone. Every member in a family should have separate face cover," the advisory stated.

Jaipur, Mar 11: A 85-year-old man in Jaipur, who had returned from Dubai on February 28, has tested positive for coronavirus, a state government official said on Wednesday.

He was found presumptive positive in the first test on Tuesday and hence, a second test was conducted with fresh samples, the reports of which arrived late Tuesday night, Additional Chief Secretary, Medical and Health, Rohit Kumar Singh, said.

“The man who travelled to Dubai has been tested positive for coronavirus. It has been confirmed now,” Singh said.

“We have also got the manifest of the Spicejet flight he took from Dubai to Jaipur and are doing due diligence on that,” the official said, adding that intense contact tracing was underway.

The man has been kept in isolation at the SMS Hospital here.

“The man came to the hospital on Monday with symptoms of the virus. After the first test, his wife and son too have been kept in isolation at the hospital. The two, however, do not have coronavirus affliction symptoms,” Singh said.

A total of 235 people who came in contact with the octogenarian and his family have already been traced and are being monitored, he said.

Other contacts are also being traced, Singh added.

An Italian couple, who tested positive for COVID-19 last week, are also admitted in the hospital but their condition is improving, he said.

Washington, Jul 1: The United States has approved four coronavirus vaccine candidates for clinical trials, Food and Drug Administration (FDA) head Stephen Hahn told reporters.

"Four vaccines have been approved for moving into clinical trials... and another six are in the pipeline for us to review," Hahn said during a press briefing on Tuesday.

The US Administration launched in May Operation Warp Speed, a joint project of Health and Defense Departments, which aims to deliver 300 million doses of a vaccine for COVID-19 by January 2021.

The country's top pandemics expert Anthony Fauci warned on Tuesday, however, that there is no certainty the United States will be able to develop a vaccine against COVID-19 that works and will be safe.

Data on vaccine effectiveness, he added, may be available in the winter or early next year.
