Muslim population rose in India because they got 'special rights': Yogi Adityanath

New Delhi, Apr 28: Nafisa Ali took to Instagram to share the inspiring story of her niece, Diya Naidu, who donated her plasma to help patients suffering from Covid-19 after recovering from the disease. The veteran actress shared a photo of her niece from the hospital bed and asked fans to read Diya's post to get a detailed account of her experience.

Nafisa wrote, "Diya Naidu my niece - a COVID19 hero - is back home after donating her plasma - looks like liquid gold - it’s value is priceless as it will save lives. So please read her COVID19 story and share the information that is first hand. It is the need of the hour. Help save lives. #diyanise. #diyanaidu #covid_19 #india (sic)."

Diya Naidu, who is a dancer and choreographer based in Bengaluru, revealed in her Instagram post that she has donated her plasma for other Covid-19 patients. She said that the method has been super effective wherever it's been tried.

Earlier, Nafisa Ali gave a shout-out to her niece on Instagram and penned a heartfelt note for her. She wrote, "I am so grateful to you brave child - a COVID19 warrior (living in Bangalore) has agreed to donate her plasma to help cure other COVID19 serious patients (sic)."

Explaining the process of plasma therapy to treat Covid-19 patients, she wrote, "The process of donating plasma to treat COVID-19 is not very complex and can be done in just two hours. One of the most discussed methods of treatment of the disease caused by the novel coronavirus is plasma therapy, which involves the transfusion of plasma from a convalescent coronavirus patient to a critical patient. The blood of a recovering patient is rich in antibodies produced by the body to fight the virus, which are expected to help the critical patient recover (sic)."

Plasma therapy has been suggested to treat people suffering from Covid-19. People, who have recovered from the disease, are donating plasma as it contains antibodies to fight the disease. Earlier, Kanika Kapoor, who was the first Bollywood celebrity to be diagnosed with the disease, also offered to donate her plasma. She has recovered from Covid-19 and is currently living with her family in Lucknow.

Thiruvananthapuram, Apr 22: Eleven more people tested positive for COVID-19 in Kerala with totalpositive cases in the State touching 437on Wednesday.

Two house surgeonsof the Kozhikode Medical college are among those who have tested positive for the virus.

The two had travelled outside the state,Chief Minister Pinarayi Vijayan told reporters.

Kannur reported seven cases, Kozhikode two, while one case each was reported from the districts of Kottayam and Malappuram.

Only one person tested negative.

The state has 127 active cases and 29,000 people are under observation, including 346 in hospitals.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
