Protecting Yourself During the COVID Surge: Masks, Vaccines, and Safe Indoor Air

Protecting Yourself During the COVID Surge: Masks, Vaccines, and Safe Indoor Air

As COVID cases surge once again, health authorities in several Australian states are recommending the reintroduction of mask-wearing. While masks have been made mandatory in high-risk areas of public hospitals in Western Australia and health-care settings throughout the country, there’s been differing opinions regarding the wider community.

Unfortunately, the SARS-CoV-2 virus, which causes COVID-19, has not transformed into a harmless common cold. In addition to initial symptoms that can be severe for vulnerable individuals, the virus has the potential to cause long-term effects on various organs and the immune system. Chronic illness and disability resulting from COVID are impacting societies worldwide. Despite public messaging encouraging us to move on from the pandemic, the virus continues to mutate, becoming more contagious and evading vaccine protection. COVID remains an epidemic virus, much like influenza or measles, meaning we can expect recurring waves of infections.

To protect ourselves, it’s crucial to recognize that SARS-CoV-2 is primarily transmitted through the air we breathe. The high transmission potential of asymptomatic individuals makes universal mask-wearing a strong recommendation during periods of increased infection rates. Masks are known to be effective, contrary to flawed claims suggesting otherwise. They not only protect the wearer but also prevent the outward emission of potentially infectious particles.

Although respirators or N95 masks provide the greatest protection, any mask is better than no mask. It is especially important to wear masks when visiting healthcare facilities, aged care facilities, shops, using public transport, and being in crowded indoor settings. Mask-wearing can significantly increase the chances of having a COVID-free Christmas.

While vaccines have faced challenges due to the virus’s evolution, they remain essential. Boosters are particularly recommended to improve immunity as vaccine effectiveness decreases over time. The World Health Organization has stressed the importance of monovalent boosters matched to the prevailing strain. In addition to vaccinations, testing, and treatment play crucial roles in managing the virus. Antivirals are available for COVID, but they require a COVID test for access. Therefore, having rapid antigen tests on hand can aid in quick isolation and treatment.

Furthermore, ensuring safe indoor air is essential as the virus spreads silently through contaminated air. Opening windows and using air purifiers in crowded indoor settings, such as schools, can significantly reduce the risk of transmission.

In conclusion, a multifaceted approach that includes masks, vaccines, testing, treatment, and improved indoor air quality will help us navigate and minimize the impact of this current wave of COVID infections.


Should I wear a mask during the rising COVID cases?

Yes, it is advisable to wear a mask, especially in high-risk areas and crowded indoor settings. Mask-wearing helps protect both yourself and others from the transmission of the virus.

Do masks really work?

Yes, masks are effective in preventing the spread of COVID-19. They prevent the outward emission of infectious particles and reduce the chance of inhaling contaminated air.

What about vaccines?

Vaccines remain essential in combating COVID-19. While the virus has evolved, boosters can improve protection, and monovalent boosters matched to the current circulating strain are recommended for better efficacy.

How can I protect myself indoors?

Ensuring good indoor air quality is crucial. Opening windows and using air purifiers can significantly reduce the risk of inhaling contaminated air, especially in crowded indoor settings like schools.
