As COVID-19 cases surge once again, the pandemic continues to disrupt everyday life. This new wave, primarily driven by a subvariant of Omicron, highlights the virus’s persistence, even as tracking systems and preventive measures have waned. Although hospitalization rates are lower, reinfections are common, and frustrations are growing, especially with rising prices for at-home test kits and limited treatment access.
Resurgent COVID-19
It’s been several years since COVID-19 first swept through the world, yet its spread shows no signs of stopping. The currently circulating strain is identified as a subvariant of Omicron. Fortunately, this variant is known to have a lower fatality and hospitalization rate than the earlier prevalent strains.
COVID-19 is Not Seasonal
COVID-19 does not exhibit the seasonal patterns seen with other respiratory viruses, as outbreaks can occur at any time of the year. Therefore, preparing for periodic surges is essential, particularly following breaks in childcare centers, kindergartens, and schools or when people gather in enclosed spaces, such as during air conditioning season.
Reasons for the Resurgence
What causes the repeated outbreaks of COVID-19? Primarily, it is due to the emergence of variant viruses. COVID-19 is classified as an RNA virus, with a higher likelihood of mutations during replication. Consequently, various variants have emerged globally, with strains like Delta and Omicron continuing to circulate persistently.
Decline in Vaccine-Induced Immunity
The decline in vaccine-induced immunity is also a contributing factor. When a new variant appears, it may evade the antibodies generated from previous infections or reduce the effectiveness of vaccines designed against earlier strains. Moreover, immunity from natural infection or vaccinations tends to wane over time, leaving individuals more vulnerable to these new variants.
Symptoms Different from Before
The symptoms of resurgent COVID-19 are similar to those seen in the early days of the pandemic, but there are some notable differences. Previously, the illness often started with a high fever, followed by sore throat, muscle aches, and fatigue, with a persistent cough and phlegm appearing later. In contrast, the current wave of COVID-19 is more commonly characterized by mild or no fever and symptoms such as cough, sore throat, runny nose, and even neurological symptoms.
Can I Take Regular Cold Medicine?
If you experience reinfection with COVID-19, it is generally acceptable to take regular cold medicine. Similar to other respiratory infections, it’s important to rest and stay hydrated. If you have a fever or headaches, over-the-counter antipyretics can provide relief. However, for children, the elderly, or individuals with weakened immune systems who exhibit severe symptoms, it is vital to seek prescription treatments from a healthcare provider.
Difference from Air Conditioning Sickness
Many people are confused by the similarities between COVID-19 and air conditioning sickness symptoms. Air conditioning sickness occurs when excessive use of air conditioning leads to a significant temperature difference between indoor and outdoor environments, causing the body to struggle to adapt. Symptoms include runny nose, sneezing, headaches, and digestive issues. However, unlike COVID-19, air conditioning sickness typically does not cause a fever, and any mild fever present is usually not sustained. If you’re unsure whether you have COVID-19, checking for fever and its duration can help clarify the situation.
Is Isolation Still Necessary?
In the past, confirmed cases were required to isolate for about a week. During this isolation period, individuals had to avoid going out and contact with others, and they could only end their isolation if they were symptom-free or showed improvement. The recommendation has shifted to 5-day isolation, which is no longer mandatory; individuals can choose whether to isolate based on their situation. However, since the virus remains highly contagious, it’s advisable to consider five days of self-isolation when possible.
Stock up on Emergency Diagnostic kits
As COVID-19 stabilizes, the use of diagnostic kits has decreased, leading to a lower supply. However, with the sudden resurgence of cases, pharmacies are experiencing temporary shortages. The federal government has announced plans to supply additional stock to pharmacies nationwide before potential outbreaks. If you stocked up during previous waves, it’s a good idea to check the expiration dates and condition of those products.
A Renewed Preventive Approach is Necessary
While it may be difficult to wear a mask all day unless the weather is cold, it’s advisable to wear one in crowded places. Wearing a mask is an essential personal preventive measure to block the transmission of infections through respiratory droplets. After going out, washing your hands thoroughly with running water for at least 30 seconds is important. If handwashing isn’t possible, using a portable hand sanitizer can also be beneficial.
