Karena Omicron telah menyebar dengan cepat, dan memiliki banyak kesempatan untuk bermutasi, Omicron juga memperoleh mutasi spesifiknya sendiri.

The Peter Doherty Institute for Infection and Immunity
The Doherty Institute is a world-class institute combining research, teaching, public health and reference laboratory services, diagnostic services and clinical care into infectious diseases and immunity. The establishment of the Doherty Institute represents a radical change in the capacity of Australia and the world to detect, investigate and respond to existing, emerging and re-emerging infectious diseases and agents, with a major focus on diseases that pose serious public and global health threats such as influenza, tuberculosis, HIV, viral hepatitis and drug resistant bacteria. The Doherty’s activities are multi-disciplinary and cross-sectoral, placing great emphasis on translational research and improving clinical outcomes. Teams of interdisciplinary scientists, clinicians and epidemiologists collaborate on a wide spectrum of activities - from basic immunology and discovery research, to the development of new vaccines and new preventative and treatment methods, to surveillance and investigation of disease outbreaks.

It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
With low COVID vaccination coverage in southern Africa, some have suggested global vaccine inequities may be responsible for the emergence of Omicron.
Protection from infection wanes over time. So boosters will offer extra protection and hopefully reduce the spread of the virus even further.
As Australia moves to the next phase of managing COVID-19, these tests will become more commonplace.
We found two small air cleaners in a single hospital room could clear 99% of potentially infectious COVID aerosols within 5.5 minutes.
The evidence suggests antigen tests are most accurate when the viral load is highest and when a person is likely to be most infectious.
Bahkan jika kita menemukan definisi tentang vaksin “terbaik”, kita tidak memiliki pilihan yang mewah, ketika persediaan vaksin terbatas.
Even if we came up with a definition of what makes the “best” vaccine, we don’t have the luxury of choice, when vaccines are in short supply.
The infection of a Victorian aged-worker who had received their first COVID vaccine dose isn’t completely surprising. We need two doses for optimal protection.
The COVID-19 variant responsible for Victoria’s latest outbreak is one of three Indian variant sub-types, which spreads more easily than the original strain. Here’s what we know so far.
The emergence of a fungal infection called mucormycosis in India is another unexpected and distressing consequence of the COVID pandemic.
Vaccination is likely to substantially reduce virus transmission by reducing the pool of people who become infected, and reducing virus levels in people who do get infected.
We have two mRNA COVID-19 vaccines so far. But what else can this technology do?
Scientists around the world are trying to come up with universal coronavirus vaccines to combat the emergence of variants. But what are these vaccines and are they even possible?
Decades of experience with influenza offers insights into how we should handle new SARS-CoV-2 variants, and the threat they pose to vaccine effectiveness.
There are many scientific and ethical challenges ahead. But these types of trials have helped in the development of vaccines against a few diseases. Could they do the same for COVID-19?
A man in the Northern Territory recently received a “weak positive” test result for COVID-19. Understanding how coronavirus tests work shows us why this can happen from time to time.
A new test, which can diagnose COVID-19 in 15 minutes, has been approved by the TGA. But it’s no silver bullet.
Saliva testing is less sensitive than a nasal swab. But in the midst of a public health crisis, in some cases a test with slightly reduced sensitivity may be better than no test at all.
