COVID-19 has not disappeared; it keeps changing shape. The latest development is a variant called BA.3.2, informally known as 'Cicada'. It has been detected in over 20 countries, including parts of the United States.
Scientists are not raising alarm, but they are watching it closely. The reason is simple; the virus keeps changing, and this variant is a clear example of that ongoing evolution.

A report of News18 suggests that BA.3.2 carries around 75 mutations. That number is unusually high. In virology, mutations happen regularly, but such a large count raises valid questions about how the virus spreads, how the body reacts to it, and whether current immunity still holds up.
Early lab findings suggest some mutations may allow partial immune escape. However, experts point out that laboratory results do not always reflect real-world outcomes. More data is still being collected.
Where has it spread?
According to the report of News18, several US states have reported cases, including California, New York, and Tennessee among them. Detections have also been confirmed across multiple countries.
Geographic spread, however, does not mean greater danger. Other variants, including XFG and NB.1.8.1, still make up a large share of infections. BA.3.2 remains one part of a wider, still-evolving picture.
Feeling unwell? Check out for these symptoms
BA.3.2 symptoms closely resemble those of recent variants. Common ones include fever, dry cough, sore throat, fatigue, headache, body aches, and a runny or blocked nose. Some people may also experience loss of taste or smell. Shortness of breath has been noted in more severe cases. How severe symptoms get depends on age, immunity levels, and existing health conditions.
Expert view
As per the Times of India report, Dr S M Fayaz, Lead & Senior Consultant Internal Medicine at KIMS Hospitals Bengaluru, puts the situation in perspective, "The evolution of SARS-CoV-2 continues to occur and the recent discovery of another variant of this virus to have multiple spike protein mutations clearly demonstrates that COVID-19 is now an endemic respiratory virus that will change over time."

At the same time, he urges calm, "However, just because a variant has emerged does not mean there is now another crisis as happened at the start of the pandemic."
Do vaccines still offer protection?
According to the report of News18, Yes. Even if BA.3.2 can partially bypass immune defences, vaccines are still expected to reduce severe illness, hospitalisation, and complications. Booster doses are especially important.
No evidence currently suggests BA.3.2 causes more serious disease than earlier strains. Basic precautions remain effective - stay vaccinated, wear masks in crowded places, maintain hygiene, and get tested if symptoms appear.
