A summer wave of COVID-19 is currently on the rise, as seen by increased hospital admissions for the virus at Vanderbilt University Medical Center in Nashville. Unlike influenza, SARS-CoV-2, the virus that causes COVID-19, does not follow a distinct seasonal pattern and can spread regardless of the time of year or temperature. This summer wave is not overwhelming hospitals due to the increased immunity from vaccines and prior infections, as well as the availability of treatments for the virus.
Wastewater surveillance data across the United States shows that viral variants of SARS-CoV-2 are spreading rapidly, especially in western states and areas that had mild winter seasons. These variants are highly infectious and have multiple mutations in the spike protein, making them more resistant to antibodies from previous infections or vaccinations. The current surge of infections is expected to continue into August, posing a significant risk to public health.
To protect against contracting COVID-19, it is recommended to maintain immunity by getting vaccinated, especially for older individuals and those with underlying health conditions. Considering that vaccines are effective in preventing severe disease and hospitalization, additional booster shots may be necessary for high-risk groups, including older individuals and those who are immunocompromised. Wearing N-95 or KN-95 masks properly can also help reduce the risk of infection.
In the event of illness, it is crucial to get tested for COVID-19 and isolate oneself until symptoms improve and a fever subsides. Even if a test comes back negative, it is advised to exercise caution and consider taking a second test to confirm the results. High-risk individuals may benefit from receiving antiviral treatments such as Paxlovid to mitigate the severity of the illness and prevent long-term complications.
COVID-19 is an endemic virus that will continue to circulate and evolve, leading to new variants and infections. However, advancements in medicine and science have provided numerous tools to manage the virus, making it more manageable than other respiratory viruses. By following public health guidelines, getting vaccinated, and taking precautions when sick, individuals can help mitigate the spread of COVID-19 and protect themselves and others from its effects.
