Fall and winter, besides being associated with the holidays, are considered cold and flu season. At the moment, though, the United States (U.S.) is in the middle of another COVID-19 summer surge. Surveillance data from the Centers for Disease Control and Prevention (CDC) states that high levels of the virus have been detected across most of the country. With the exception of 19 states, COVID-19 cases are very high, especially in the western part so the U.S.
Although it is inconvenient, it is very normal for COVID cases to spike during the summer. In fact, it has happened every summer since COVID-19 arrived on the scene. Why do cases increase, though? Below, we will explain why it tends to happen during the summer months and how you can protect yourself from the virus.
What Is A Summer Surge?
A COVID summer surge is defined by an unexpected increase in the number of COVID cases during the summer months, according to infectious disease specialists. Other than allergies, mild infectious illnesses like the cold and flu are common during fall and winter. That said, viruses can surge any time of the year. A COVID surge in the summer is common because people travel more and gather in large groups indoors and outdoors.
The virus continues to evolve and stays ahead of the immune system. The immune system recognizes the infection of past variants as new ones appear, which can lead to an increase in new infections. And over the years, health experts have observed a big surge in COVID-19 cases at the beginning of summer.
What Is Causing The Current Surge?
There isn’t just one cause that health experts can blame for the increase in COVID cases. The first of many causes is that people do not have immunity to the new variants. Immunity to prior COVID infection is short-lived. In fact, immunity can wane after just three months. That means that you need a new strategy if you plan to rely on your immunity to protect against COVID-19 infection. Perhaps that looks like getting a COVID booster vaccine, which is given out similarly to the flu vaccine nowadays.
The COVID-19 FLiRT variants are largely driving this summer surge, though. These variants are more adept at evading the immune system. The weather may also factor into the equation. Some health experts explain that the emerging variants potentially thrive more in the heat than they do in the cold. That could cause an increase in COVID cases in the summer, as opposed to late fall and early winter. Additionally, the extreme heat, which is present across the country, drives people to gather indoors.
Is it possible that the 2024 Summer Olympic Games will cause an uptick in COVID-19 cases? It’s always possible because large gatherings, be they indoor or outdoor, are the perfect environment for the virus to spread easily. That is true for people having guests over to their houses to watch the Olympics, or for attendees watching the games in person. In fact, there is already evidence of some olympic athletes testing positive since the start of the Summer Games.
Will The COVID Surge Continue?
Health experts anticipate that the surge will continue as summer comes to a close. As long as people gather indoors and travel, transmission remains a worry. That said, infectious disease specialists are hopeful that another surge will not hit until late fall, or even early winter when people travel to see family for the holidays. If people take precautions, though, there is a chance that another spike in cases will not occur. It’s also possible that another surge will not be as big as the summer surge.
How Do You Protect Yourself During Surges?
In order to prepare for a surge and reduce your risk of infection during summer, health experts encourage the following:
- Test regularly for COVID-19, especially if you live with high-risk individuals
- Open your windows if you have a large gathering
- Practice good hygiene by washing hands regularly and using hand sanitizer
- Wear a mask in crowded indoor spaces, especially if you have a loved one who is immunocompromised
- Use a HEPA air filtration system to reduce the risk of transmission
- Stay up-to-date on boosters and vaccinations
