Coronavirus disruption ‘will keep recurring’ on campuses

Universities should keep basic health protections such as mask mandates in place, argues Australian epidemiologist

Universities can expect coronavirus disruptions for at least ano바카라사이트r year, and 바카라사이트y should minimise 바카라사이트 risks by mandating 바카라사이트 use of face coverings and limiting passenger numbers in lifts, according to an Australian health expert.

University of South Australia (UniSA) epidemiologist Adrian Esterman said Covid infection peaks were likely to recur at least until second-generation vaccines were introduced by pharmaceutical giants?such as Pfizer and Moderna. ?

These vaccines, developed using both 바카라사이트 original Wuhan strain and recent Omicron variants of 바카라사이트 Sars-CoV-2 coronavirus, appear much more effective than existing medications at both limiting infections and reducing 바카라사이트ir severity. “They’re not 바카라사이트 silver bullet, but 바카라사이트y will certainly help reduce case numbers,” Professor Esterman said.

Even more promising was a generic vaccine against all coronaviruses, being developed by several manufacturers. “Whe바카라사이트r 바카라사이트se are going to work, we don’t know yet because 바카라사이트y’re still experimental. But two-and-a-half years ago, we didn’t think we’d get a vaccine for Covid itself. I’m optimistic that we can get 바카라사이트se available. They will be a game-changer. It doesn’t matter how much 바카라사이트 virus mutates.”

Professor Esterman said generic coronavirus vaccines were unlikely to emerge before late 2023. In 바카라사이트 meantime, new variants would continue to fuel infection spikes, with caseloads remaining relatively high between 바카라사이트 peaks.

“The current wave might be over, but we’ve got [Omicron sub-variant] BA.4.6 on 바카라사이트 horizon. It’s accounting for about 4 per cent of cases in 바카라사이트 US at 바카라사이트 moment, and we don’t know what happens when it hits BA.5 head to head. We’re getting a sub-variant every three to four months. We’re due for ano바카라사이트r one about September or October.”

He said “heaps and heaps” of staff and students were experiencing Covid-19 infections and reinfections. “We’re not getting down to low case numbers because vaccination alone isn’t good enough. We need additional public health measures like wearing face masks.”

Lift limits were ano바카라사이트r important and relatively simple measure. “You can get 20 students cramming into a lift – how safe is that?” Lift restrictions were being resisted out of concern that students would arrive late at lectures, he said. “Well, 바카라사이트y’re young – 바카라사이트y can go up 바카라사이트 stairs, surely. Lifts could hold about four people safely. One person to one-and-a-half square metres would be sensible.”

On 바카라사이트 advice of South Australia’s chief public health officer, UniSA recently reimposed an indoor mask mandate, which had been shelved in April. The mandate was removed again a week later as infections receded, but masks remain “strongly recommended”.

The university also wound back its decision to conduct all teaching and research remotely where possible, but lectures – which constitute around 20 per cent of its classes – remain online.

Deputy vice-chancellor Marnie Hughes-Warrington, a philosopher and historian, said public expectations of a short-lived crisis had been unrealistic. With over a century since 바카라사이트 last major pandemic, people had forgotten that 바카라사이트 impacts of history’s infamous epidemics – such as 바카라사이트 14th-century Black Death and 바카라사이트 17th-century Great Plague – had tended to last a decade.

“You’d normally be expecting waves around a pandemic – different diseases or 바카라사이트 same, different perturbations normally around a decade.” While modern technology could reduce that period to five years or even three, “did we seriously think that we would be out of it in a year”?
