Researchers have found under which conditions and in which ways, masks actually reduce individual and population-average risks of being infected with Covid-19 and help mitigate the coronavirus pandemic.

The study, led by researchers from the Max Planck Institute for Chemistry in Germany’s Mainz, showed that in most environments and situations, even simple surgical masks effectively reduce the transmission of SARS-CoV-2 and the effective reproduction number for Covid-19.

“For the airborne transmission of SARS-CoV-2, we find that usually just a minor fraction of exhaled respiratory particles contain viruses. Most environments and contacts are under virus-limited conditions, wear face masks, including simple surgical masks, have a high efficacy in preventing the spread of Covid-19,” said Yafang Cheng, the head of the Minerva Research Group at Max Planck.

In environments with potentially high airborne virus concentrations such as medical settings and densely occupied indoor spaces, masks with higher filtration efficiency (N95/FFP2) should be used and combined with other protective measures such as intensive ventilation. In most situations, even simple surgical masks are effective.

“The combination of high-efficiency masks with other protective measures is particularly important for hospitals, medical centers, and other indoor environments, where high-risk patients may encounter high virus concentrations,” said Christian Witt, head of the Research Area Pneumology at the Charite Universitatsmedizin Berlin.

“Masks will remain an important protective measure against SARS-Cov-2 infection — even for vaccinated persons, especially when the protection provided by vaccination decreases over time,” Witt said.

For the study, published in the journal Science, the team used observational data and a novel quantitative model of airborne virus exposure to elucidate how the efficacy of face masks depends on characteristic regimes of airborne virus concentration.

The approach can be used to assess protection against more infectious mutants of Covid. It is also applicable to a wide range of respiratory viruses and diseases, including coronaviruses, rhinoviruses, and influenza.

The findings showed that aerosol transmission does not necessarily lead to very high reproduction numbers as observed for measles and that relatively low reproduction numbers do not rule out airborne transmission. (IANS/KB)

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday with a focus on vaccines delivery initially. "This is going to be a pilot project for the area. The drone is developed and manufactured entirely by our scientists," Union Minister for Science & Technology, Dr Jitendra Singh told mediapersons. Singh said he himself will be launching the project at Jammu.

The drone is developed by the scientists at Bengaluru's National Aerospace Laboratories (NAL), a constituent of Council of Scientific and Industrial Research (CSIR), an autonomous Society that is headed by the Prime Minister. For now, the delivery would be limited to Covid vaccines and once successful, it would be expanded to be used for regular delivery of medicines in the remote, hilly areas.

According to him Amitabh Bachchan is a great actor in the industry.

Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.

Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."

According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."

"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
