Israel's Sudden Covid Surge Despite Mass Vaccinations

Israel, a world leader in Coronavirus vaccinations, has been reporting high daily infection rate since over three months as it scrambles to contain the spread of the new delta variant. Despite mass vaccinations, authorities are racing to give shots to children and are considering tighter travel restrictions at the country’s main airport.

Most Israelis were vaccinated with the Pfizer vaccine, which, as per the research available, is shown to be less effective than the Moderna vaccine against the virus and this could be among the key reasons for spike in infections.

While Israel was among the first countries to begin vaccination for children and rolled out a booster shot of the Pfizer-BioNTech vaccine, research suggested the vaccine’s efficacy had reduced over time. Around 100,000 Israelis are getting inoculated every day, the vast majority of them with a third shot, it reported.

Israel saw a steep rise in cases, reaching an all-time high of 11,316 daily cases on September 2. However, the number of people needing hospitalisation has been low compared to the last coronavirus wave in mid-January. Green passes, that showed a person has been vaccinated or has recovered from the virus, were made compulsory for entertainment, sports, and cultural venues, gyms, cafes and hotels.

Airborne transmission of Covid-19 random, social distancing alone not enough to control spread: Study

A new study new study has shown that the airborne transmission of Covid-19 is highly random and suggests that social distancing alone is not effective in controlling its spread, reiterating the importance of vaccination and face masks.

“One part of the way that this disease spreads is virology: how much virus you have in your body, how many viral particles you expel when you speak or cough,” said Dr Shrey Trivedi, the Indian-origin first author of the study published in the journal ‘Physics of Fluids’ this week.

“But another part of it is fluid mechanics: what happens to the droplets once they’re expelled, which is where we come in. As fluid mechanics specialists, we like the bridge from virology of the emitter to the virology of the receiver and we can help with risk assessment,” explained Trivedi from the Department of Engineering at the University of Cambridge.

Air pollution linked to increased risk of getting sick from Covid-19: Study

Published

According to a study conducted in Spain, long-term exposure to air pollution is associated with an increased risk of developing Covid-19 among people who get infected with the SARS-CoV-2 virus.

The research, published in the journal Environment Health Perspectives on Wednesday, provides further evidence on the health benefits of reducing air pollution, and highlights the influence of environmental factors on infectious diseases.

“The problem is that previous studies were based on reported cases, which had been diagnosed, but missed all the asymptomatic or undiagnosed cases,” said study first-author Manolis Kogevinas from Barcelona Institute of Global Health (ISGlobal) in Spain.
