UK scientists to test extent of airborne COVID-19 transmission

  • COVID-19 is known to be present in droplets produced from the mouth and nose from people coughing, sneezing, talking or just breathing
  • Findings could affect governments’ safety measures based on climate, air quality

LONDON: A team of UK scientists is set to discover how long COVID-19 can survive in airborne particles.
In an experiment slated to commence on Monday, researchers at the University of Bristol will test whether the virus is at its most virulent in respiratory droplets, or whether it remains active over significant periods in tiny aerosol particles.
COVID-19 is known to be present in droplets produced from the mouth and nose from people coughing, sneezing, talking or just breathing.
But these remain airborne, and therefore active, for a much shorter period of time than aerosol particles before dropping to the floor.
This is the reasoning behind multiple governments’ enforcing social-distancing measures of 2 meters, among other things. 
But were the virus able to survive in much smaller aerosol particles, it is possible that it could travel greater distances — carried by air currents and ventilation systems — and infect more people, rendering social-distancing measures less effective. 
The theory has gained traction as examples from across the world of groups of people being infected despite observing social-distancing measures, or doing so in poorly ventilated spaces.
Prof. Jonathan Reid, who is leading the Bristol team, told The Guardian newspaper: “We know that when bacteria or viruses become airborne in respiratory droplets they very quickly dry down and can lose viability, so that’s an important step to understand when assessing the role of airborne transmission in COVID-19.”
Allen Haddrell, a scientist at the University of Bristol, said: “We can effectively mimic a cold, wet British winter — or even a hot, dry summer in Saudi Arabia — to look at how these dramatic differences in environmental conditions affect how long the virus remains infectious while suspended in air.”
Results will possibly ready by the end of the week for external scrutiny by the broader scientific community.
Despite excitement surrounding the experiment, some scientists have urged caution, especially regarding the scope of practical applications that could result from it.
“I think the science is fine, and will show the principal that you can modify the environment to reduce the survivability of the virus,” said Dr. Julian Tang, a consultant virologist at Leicester Royal Infirmary.
“But the applicability might be tricky, depending on the environmental factors they identify. You’re not going to sit in a theater or cinema if the temperature is 35 degrees and the humidity is 80 percent.”


Indonesian president ‘honored’ to have UAE street named after him

Indonesian president ‘honored’ to have UAE street named after him

  • Abu Dhabi’s Al-Ma’arid Street renamed President Joko Widodo Street

JAKARTA: Indonesian President Joko Widodo on Tuesday said it was “an honor” for him and his country that a street in the UAE capital had been named after him.

Al-Ma’arid Street, one of Abu Dhabi’s key roads, was on Monday renamed President Joko Widodo Street during a ceremony that coincided with the first anniversary of the Indonesian leader’s inauguration for a second term in office.

Writing on social media, Widodo said: “It is a recognition and an honor, not only for me, but for Indonesia.” He also expressed hope that the two countries’ relations would be “stronger, mutually strengthening, and beneficial for the people of the United Arab Emirates and Indonesia.”

Indonesia’s ambassador to the UAE, Husin Bagis, told Arab News: “The initiative to rename the street after President Joko Widodo came from His Highness (Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed Al-Nahyan), who also presided over the street renaming ceremony on the spot.”

The envoy said that the street was near to the future location of the Indonesian Embassy compound, which was currently under construction.

According to UAE news agency WAM, the crown prince has also directed officials to build a mosque named after Widodo, in Abu Dhabi’s Diplomatic Area, in recognition of the Indonesian president’s close friendship with the UAE and his efforts to strengthen the relationship.

Indonesia-UAE relations have grown closer since Widodo’s visit to Abu Dhabi in January, during which he secured investment projects worth $22.9 billion in what has officially been described as the biggest trade deal in the country’s history. The visit was to reciprocate the crown prince’s trip to Indonesia in July 2019.

Recent cooperation agreements between the two countries have included plans for the construction of a mosque on a plot of land in Widodo’s hometown of Solo in Central Java.

The mosque will be a replica of Abu Dhabi’s Sheikh Zayed Grand Mosque and serve as an Islamic center offering training for clerics. A groundbreaking ceremony is slated to take place in December.

Widodo is the latest Indonesian leader to be celebrated through an honorific street name in a foreign country. In Rabat, Morocco’s capital, Avenue Sukarno was named after Indonesia’s first president, while Mohammed Hatta Street in Haarlem, the Netherlands, recognizes the Southeast Asian country’s first vice president. Sukarno and Hatta are considered the fathers of Indonesia’s independence.

The name of the country’s third president, B. J. Habibie, appears on a bridge in Dili, the capital of East Timor, in honor of his decision to hold a referendum there which allowed East Timor to secede from Indonesia.
