Omicron has caused many more breakthrough infections than previous COVID-19 variants have. Even though COVID-19 vaccines and booster doses are doing their job by protecting against serious illness, it’s still discouraging to positive for the virus after protecting yourself. So, why does this happen?

Our AFC Urgent Care Louisville team provides some helpful answers below, so keep reading.

What Are Breakthrough Infections?

According to the CDC, breakthrough infections happen when a person tests positive for COVID-19 at least two weeks after being fully vaccinated, including getting a booster dose when eligible.

Why does omicron cause more breakthrough infections than previous variants? Omicron is substantially more transmissible because of its different mutations. In addition to omicron coming around as natural immunity was beginning to wane, its mutations allow the variant to circumvent the passive immunity established by early COVID-19 immunizations. The first signs of omicron are likewise not quite the same as earlier forms of the virus, and we’ve listed them below.

Common Initial Omicron Symptoms

• Cough
• Fatigue or tiredness
• Congestion and runny nose
• Sore throat
• Headache

Do Booster Shots Protect Against the Virus?

Yes, they do! The CDC has stated that breakthrough infections are common right now, but the fact remains that although initial infection happens, studies have shown that booster shots are 90% effective in preventing hospitalizations and serious illness.

In addition to getting vaccinated and boosted when eligible, the following are some extra steps you can take to lower your risks of testing positive for the virus.

Ways to Prevent Infection

• Wear a well-fitting N95 or KN95 mask. These offer the highest level of protection, according to the CDC.
• Wash your hands with soap and water thoroughly and often. Make sure to wash for at least 20 seconds each time to properly rid of lingering bacterial and viral particles.
• Be smart with where you go and the events you attend. Even though physical distancing is still recommended by the CDC, not many adhere to it anymore. If you are immunocompromised, live with someone who is at high risk of becoming seriously ill or you have young children at home, you may want to be more cautious and keep your distance in public.
