New COVID Variant ‘Cicada’ Spreads Across US: Symptoms, Risks And What To Know

A newly identified COVID-19 variant called BA.3.2, also known as "Cicada," is drawing attention as it spreads across the United States. Health experts and researchers are closely tracking this variant to understand how it spreads, how it behaves, and whether it could affect immunity.

The variant has been detected through multiple monitoring systems, including travellers, patient samples and wastewater, suggesting that its spread may be wider than currently known.

What Is the BA.3.2 'Cicada' Variant?

BA.3.2 is a new lineage of the coronavirus that is different from earlier variants that have been circulating in recent years. It is genetically distinct from the JN.1 family of variants that dominated infections in many countries.

One of the key features of this variant is a high number of mutations in the spike protein. Scientists say it carries around 70 to 75 mutations in this part of the virus, which helps it enter human cells.

Because of these changes, researchers believe the variant may have the ability to partially escape immunity gained from past infections or vaccinations.

Where Has It Been Found?

Health authorities in the United States have detected BA.3.2 in several ways. It has been found in samples taken from travellers, patients and even wastewater, which is often used to track community spread.

The variant has been reported in many US states, including California, Florida, New York, Texas, Illinois and several others. Experts warn that the actual spread could be wider, as not all cases are tested or genetically analysed.

Global Presence and Origin

Although the variant is gaining attention now, it was first identified in South Africa in November 2024. Over time, it spread to other parts of the world.

By mid-2025, it had reached the United States through international travel. Later, it was also detected in several European countries, including Denmark, Germany and the Netherlands, where it accounted for a notable share of cases.

Its nickname, "Cicada," reflects how it stayed under the radar for some time before becoming more visible.

Symptoms of the New Variant

So far, the symptoms linked to BA.3.2 appear similar to other COVID-19 variants. However, some doctors have noted that a severe sore throat is commonly reported.

Other common symptoms include cough, fever, fatigue, headache, body aches, congestion, and in some cases, loss of taste or smell. Some people may also experience nausea, diarrhoea or shortness of breath.

At present, there is no strong evidence to suggest that this variant causes more severe illness than previous ones.

Will Vaccines Still Work?

Experts say that current COVID-19 vaccines are still expected to protect against severe illness, hospitalisation and death. However, because of the high number of mutations, there are concerns that the effectiveness of vaccines against infection may be slightly reduced.

Health organisations are continuing to study how well existing vaccines and treatments work against this variant. More data is needed to fully understand its impact.

Could It Lead to Another Surge?

It is still unclear whether BA.3.2 will cause a major increase in cases. Some experts believe it has the potential to drive a new wave of infections, especially if it spreads quickly.

However, others say it is too early to predict its impact. The situation will depend on how the variant evolves and how well existing immunity holds up.

Why Experts Are Watching Closely

Health authorities around the world are closely monitoring BA.3.2 because of its mutation profile and its ability to spread across regions. They are also concerned that gaps in testing and surveillance could mean the variant is more widespread than reported.

Continuous monitoring will help experts understand how the virus is changing and what steps are needed to control its spread.
