New BA.3.2 'Cicada' Variant: Key Symptoms, Differences from Earlier COVID Strains and Whether You Should Be Concerned
A new COVID-19 subvariant, commonly referred to as 'Cicada', is drawing attention as it begins to spread across multiple countries. While it has been detected in over 20 nations, experts say it is not yet the dominant strain globally. The variant, officially known as BA.3.2, belongs to the Omicron lineage but carries several unique characteristics that set it apart.
What is BA.3.2 “Cicada”?
The BA.3.2 subvariant was first identified in South Africa in November 2024. It stems from the BA.3 lineage, which itself is part of the broader Omicron family that emerged in late 2021.
What makes this variant notable is the unusually high number of mutations, around 70 to 75, particularly in its spike protein. These changes may influence how the virus behaves, especially in terms of transmission and immune response.
Laboratory findings suggest that BA.3.2 can partially evade antibodies due to these mutations. However, experts stress that this does not necessarily translate into more severe illness.
"There’s no evidence that BA.3.2 is causing more severe disease or hospitalizations in countries where it’s more widespread," Dr. Adolfo García-Sastre explained. "It can still cause problems, of course, but it's not a more problematic strain that previous ones."
Common Symptoms of the Cicada Variant
The symptoms linked to the BA.3.2 variant remain largely similar to earlier COVID-19 strains. These include:
Most cases reported so far are mild and manageable at home.
How is “Cicada” Different from Earlier Variants?
1. Higher Mutation Count
“Cicada” (BA.3.2) carries around 70-75 mutations, significantly more than many earlier Omicron subvariants.
2. Potential to Bypass Immunity
These mutations may allow the virus to partially escape protection from previous infections or vaccinations, possibly leading to breakthrough cases.
3. Transmission Behaviour
Like other Omicron variants, it spreads efficiently—especially in crowded indoor environments and poorly ventilated spaces.
4. No Increased Severity (So Far)
Unlike earlier variants such as Delta, there is currently no indication that BA.3.2 causes more serious illness.
5. Slower Spread Pattern
Instead of triggering a sudden surge, this variant appears to be spreading gradually without causing a major global spike.
6. Vaccines Still Offer Protection
Although infections may occur, existing vaccines continue to provide strong protection against severe disease, hospitalisation, and death.
How Does the Cicada Variant Spread?
The BA.3.2 variant spreads in ways similar to other COVID-19 strains:
Its transmissibility may be higher, which explains its presence in multiple countries.
Is BA.3.2 More Severe?
Current data suggests that BA.3.2 does not lead to more severe illness compared to earlier variants. There has been no unusual rise in hospitalisation rates linked to this strain so far.
Vaccines and booster doses continue to play a crucial role in preventing serious outcomes, particularly among vulnerable groups.
Treatment and Recovery
For most people, infection with the Cicada variant results in mild illness. Recovery can usually be managed at home with:
Mild cases typically resolve within a few days to a week. However, individuals at higher risk—such as the elderly or those with underlying health conditions - should seek medical attention early. Antiviral treatments may be recommended in moderate to severe cases.
Should You Be Worried?
At present, there is no evidence of a large-scale outbreak linked to BA.3.2 in India. However, health experts warn that global travel could contribute to its gradual spread over time.
Authorities are closely monitoring the situation, and the overall advice remains unchanged: stay cautious but avoid panic.
Prevention Tips to Stay Safe
BA.3.2 “Cicada” is a highly mutated COVID-19 variant that is spreading slowly across countries. While its mutations raise concerns about immune evasion, there is no clear evidence yet that it causes more severe disease.
Experts recommend staying alert, following basic precautions, and relying on vaccination as the best defence - focusing on vigilance rather than fear.

- Fever or chills
- Sore throat
- Nasal congestion
- Shortness of breath
- Loss of smell or taste
- Fatigue
- Headache
- Diarrhoea or vomiting
