Here’s What to Know About BA. 3.2

April 7, 2026

A heavily mutated COVID-19 variant nicknamed "Cicada" (BA. 3. 2) is primarily infecting children aged 3-15, though it is not causing more severe illness in any age group.

Who is affected

Children between ages 3 and 15 (approximately five times more likely to be infected compared to other variants)
Residents in 23 countries where the variant has been detected
Populations in 25 US states where the variant has been found in wastewater
A 5-year-old boy in South Africa (first known case in November 2024)
A traveler from the Netherlands to the US (first US case last summer)
German population (experienced 30% of infections from November through January)

What action is being taken

The US Centers for Disease Control and Prevention is monitoring the variant and published a report last month
Scientists are tracking the virus in wastewater across 25 US states
Dr. Marc Johnson is closely tracking the virus's presence in wastewater
Researchers at Mount Sinai are studying how updated COVID-19 vaccines perform against BA.3.2
Experts are observing the variant to ensure it doesn't change in problematic ways

Why it matters

This variant represents a significant shift in COVID-19's typical infection pattern, which has primarily affected older adults rather than children. Understanding why BA.3.2 preferentially infects children helps scientists better predict how the virus evolves and behaves. The variant demonstrates how chronic infections in immunocompromised individuals can serve as incubators for highly mutated strains. Despite its 53 spike protein mutations, BA.3.2's reduced ability to bind to ACE-2 receptors shows that more mutations don't necessarily mean greater threat, providing valuable insight into viral evolution. The variant's behavior resembles traditional respiratory viruses like influenza, suggesting COVID-19 may be transitioning toward more predictable seasonal patterns.
