New Delhi, March 31: A new subvariant of COVID-19, scientifically labeled BA.3.2 and nicknamed “Cicada,” is drawing global attention after being detected in at least 23 countries. First identified in late 2024 and recently resurging in the United States, this highly mutated strain is being closely monitored by health authorities. Despite its complex mutation profile, experts say there is currently no clear evidence that it causes more severe illness than earlier COVID-19 variants.

What Makes the BA.3.2 ‘Cicada’ COVID-19 Variant Different?

The BA.3.2 subvariant belongs to the Omicron lineage of COVID-19 but stands out due to its unusually high number of mutations. Scientists estimate it carries around 70 to 75 changes in its spike protein, the part of the virus targeted by most COVID-19 vaccines.

These mutations may help the virus partially evade immunity from past infections or vaccinations, potentially increasing breakthrough COVID-19 cases. However, vaccines are still considered effective at preventing severe disease, hospitalization and death. New COVID-19 Variant BA.3.2 ‘Cicada’ Spreading Across US: Check Its Symptoms, Spread, and Other Details.

BA.3.2 ‘Cicada’ COVID-19 Variant Symptoms

Symptoms linked to the BA.3.2 COVID-19 variant are largely similar to previous Omicron-related COVID-19 infections. Most cases reported so far are mild to moderate and manageable at home. Common symptoms include:

  • Persistent cough and sore throat

  • Nasal congestion and shortness of breath

  • Fever or chills

  • Fatigue and headaches

  • Loss of taste or smell

  • Gastrointestinal issues such as diarrhea or vomiting

People experiencing COVID-19 symptoms are advised to get tested and isolate if necessary to prevent further spread.

Transmission and Spread of COVID-19 BA.3.2

Like other Omicron subvariants, the BA.3.2 COVID-19 variant spreads efficiently, particularly in crowded or poorly ventilated indoor spaces. However, unlike earlier waves of COVID-19, its growth has been more gradual rather than explosive. What Is Tuberculosis? US Sees Rise in TB Cases; Check Symptoms and Risks.

Experts note that while transmission rates are high, there has not been a corresponding surge in severe cases or hospitalizations so far.

Public Health Advice and Precautions

Health authorities stress that there is no need for panic but continued vigilance is essential. Staying up to date with COVID-19 booster doses remains a key defense, especially for elderly individuals and those with underlying conditions.

Basic precautions such as hand hygiene, mask use in high-risk settings and timely testing continue to be effective in limiting the spread of COVID-19.

In summary, while the BA.3.2 ‘Cicada’ COVID-19 variant shows increased transmissibility and immune evasion, current evidence suggests it behaves similarly to other Omicron strains, with manageable symptoms and strong protection from vaccines against severe outcomes.
