''' AIRBORNE PATHOGENS AIRWAVES '''

!WOW! : " THE HONOUR THAT BELONGS TO THE STUDENTS.'' With a goal to keep the world safe, peaceful, dignified and happy. ' Welcome, to all parents of the world. '

'' AFTER PANDEMIC - A GOAL TO KEEP INDOOR AIR SAFE.'' Scientists aim to devise systems that detect floating hazards and mitigate risks.

Linsey Marr - an environmental engineer stood next to a pair of clear plastic boxes packed with tubes, nozzles and electronics, an odd-looking prototype that one day might serve to protect children in day care from airborne pathogens.

A nozzle filled the right-hand box with a faint silvery mist. A pump pulled some of that air into the left-hand box, where a sampler trapped floating particles and droplets. Soon, a digital screen bolted to the box turned red : '' Detected! Dust mite allergen Der f 1 .''

A protein shed by dust mites, Der f 1 can trigger asthma attacks when inhaled, Dr. Marr's device had detected 843 programs of Der f 1 per cubic meter. A single grain of salt is about 10 million times as heavy.

'' Before this instrument, it would have taken us two days to figure out how much was in the air,'' Dr. Mart said. '' Now we're doing it almost in real time.''

Dust mite allergens are not the only threats that Dr. Marr's team aims to fish from the air. The technology, still evolving, can already sniff out influenza, the coronavirus and E. coli.

'' We have 10 different things that we're able to detect, and by the end of the program, there will be 25 different things,'' she said.

Dr. Marr was shouting over the din on the fifth floor of a Washington office building where 200 people milled about, getting first look at a rapidly evolving frontier in science : technology designed to keep indoor air safe in day care centers, schools, hospitals - any where people gather.

This grown-up science fair was hosted by the Advanced Research Projects Agency for Health -ARPA-H for short - which is spending $150 million to create what it calls '' an immune system for every building.''

At the start of the event, the program manager, Jessica Green, gave a brief welcome speech. '' We have the right to be breathing healthy indoor air,'' she said.

Dr. Green was echoing the words of William and Mildred Wells, a husband and-wife team who discovered the threat of airborne germs in the 1930s. They famously protected children in Philadelphia schools from a measles epidemic in the 1940 by installing ultraviolet lamps that disinfected classroom air.

'' I believe that a provision of pure air for children [ and adults ] to breathe should be looked upon as of equal importance to the provision of pure water and pure milk,'' Mildred Wills later wrote.

But she and her husband failed to sway their colleagues, and the threat of airborne germs went underappreciated for generations.

When Covid hit in 2020, the World Health Organization emphatically stated that it was not airborne -which turned out to be wrong.

Dr. Marr, who teaches at Virginia Tech, played a leading role in getting the public health authorities to recognize that the coronavirus SARS-CoV-2 was in fact airborne.

She and other researchers were frustrated by how hard it could be to identify such pathogens.

'' We'd spend a day collecting samples onto a filter, we could take it to the lab, and the next day it will take us several hours to figure out how much is in there,'' Dr. Marr said.

'' And by the time you have that number, it's too late to do anything about it.''
