The U.S. has witnessed a rise in COVID-19 cases and hospitalizations in the recent weeks, signaling a possible surge during the summer season. According to the Centers for Disease Control and Prevention (CDC)’s recent data, the U.S. has had an increase of 0.8% in test positivity, 13.3% in hospitalizations, and 18.2% in emergency department visits due to COVID-19. While the death rate from the virus has seen a 25% decrease, the upswing in infection rates and hospital visits is unignorable, and calls for a comprehensive understanding of what’s causing this surge and how to manage it.
Despite the uptick in cases, Dr. Charles Bailey, Medical Director for Infection Prevention at Providence St. Joseph and Providence Mission Hospitals in Aliso Viejo, California, instills a note of reserved optimism. He maintains that these fluctuations are normal and expected in endemic COVID activity. The COVID activity currently being experienced is relatively low compared to the heavy burden witnessed during the earlier pandemic period. Therefore, the current rise does not necessarily trigger unwarranted concern about an imminent significant resurgence.
As for the causes behind the surge, multiple factors are in play. It could be a change in COVID-19 variants, waning effectiveness of vaccinations depending on the time elapsed since vaccination, reduction in natural immunity due to previous low infection rates, or abandoning of public health practices such as social distancing and mask wearing. Dr. Bailey further explains that infection contraction is an outcome of many factors, including the infecting agent’s strength, host immunity, overall health, exposure odds, and exposure intensity.
The CDC has outlined robust guidelines for those who test positive for COVID-19 during the summer. Upon infection, one should retreat to their home until symptoms resolve, then wait an additional 24 hours before resuming activities. Over the subsequent five days, additional safety measures such as retesting, improving air quality, enhancing hygiene, masking properly, and maintaining distance are recommended for optimal recovery and to prevent further transmission.
Current CDC advisories are more relaxed than those in place during the early pandemic days in 2020. Dr. Bailey has supported this recent relaxation, asserting it as ‘reasonable’, as it appropriately balances disease control and maintaining life norms essential for mental and financial well-being. He further recommends that symptomatic individuals, those exposed to COVID-19, and high-risk groups in preparation for major surgeries should be proactive in taking COVID-19 tests.
In conclusion, while there is a noticeable upswing in COVID-19 cases and hospitalizations, it is not an unexpected phenomenon due to summer social activities and lackadaisical adherence to safety measures. Nevertheless, it remains critical to stay vigilant, continue testing when necessary, and adhere to CDC guidance for personal and public well-being.
