California’s Devastating Summer COVID Surge: Reasons Explained.

California is facing a strong wave of COVID this summer. One reason is a new mutation of the virus. The heat waves and wildfires have kept people indoors, making it easier for the virus to spread. Many adults are also more vulnerable because they haven’t been exposed to the virus recently. The virus has changed, too. There is a new subvariant called KP.3.1.1 that is highly contagious. Even people who haven’t had COVID before are getting sick. COVID cases are increasing, but hospitalizations are still lower than in past summers. The World Health Organization is concerned about the rising infections worldwide. It’s important to keep testing for COVID, as symptoms can be similar to allergies. Wastewater data shows high levels of the virus in California. It’s essential to follow safety measures like wearing masks in crowded indoor places to stay safe.
