A new COVID-19 variant called BA.3.2 which is popularly known as the ‘Cicada variant’ has started to gain the global attention in 2026. This variant is belongs to the Omicron family but stands out because to its high number of mutations and unusual reappearance pattern. The World Health Organization has placed the variant ‘Variant Under Monitoring’. It means that it is being closely tracked but is not currently causing a major global health emergency.
Why Is It Called the ‘Cicada’ Variant?
The term ‘Cicada’ is not an official scientific name but a popular nickname of the virus. It shows how this variant has emerged after staying hidden for a long time and then suddenly it is reappearing.
Just like cicadas that remain underground for years before emerging BA.3.2 evolved from the older and it have nearly disappeared lineage and resurfaced with new mutations. With this it is attracting attention from scientists and health experts.
Origin and Evolution of BA.3.2
The BA.3.2 variant is part of the Omicron lineage and which has been evolving continuously since January 2021.
Origin & Spread Timeline
| Aspect | Details |
| First detected | South Africa (Nov 2024) |
| Global spread | Early 2026 |
| Detection methods | Testing & wastewater surveillance |
| Current status | WHO Variant Under Monitoring |
Over the time this variant has developed the sub-lineages like BA.3.2.1 and BA.3.2.2 and which is indicating ongoing mutation and evolution.
What Makes BA.3.2 Different? (Mutation Profile)
The defining feature of this variant is the large number of mutations especially in the spike protein.
Mutation Overview
| Feature | Details |
| Total mutations | Nearly 70–75 (mainly spike protein) |
| Type | RNA virus |
| Origin lineage | BA.3 (Omicron sub-lineage) |
| Evolution | Highly divergent |
| Sub-lineages | BA.3.2.1, BA.3.2.2 |
These mutations may help the virus to,
- Spread more efficiently
- Partially evade immune responses
Symptoms of Cicada Variant BA.3.2
Most infections which was caused by BA.3.2 are mild to moderate and they are similar to earlier Omicron variants.
Symptoms of Cicada variant
| Category | Symptoms |
| Common | Fever, cough, sore throat, fatigue |
| Body-related | Headache, muscle pain, weakness |
| Additional | Runny nose, sneezing |
| New observations | Night sweats, stomach issues |
| Severe (rare) | Breathing difficulty, chest pain |
Transmission: How It Spreads
The BA.3.2 variant spreads in the same way as other COVID variants spread through airborne droplets.
Transmission Characteristics
| Factor | Impact |
| Mode | Airborne droplets |
| High-risk areas | Crowded indoor spaces |
| Ventilation | Poor airflow increases spread |
| Mutation effect | Possibly higher transmissibility |
Comparison with Earlier Variants
Understanding the BA.3.2 variant when compares with earlier variants helps in assessing its impact.
Variant Comparison
| Feature | Delta Omicron BA.3.2 |
| Severity | High Moderate Mild (current evidence) |
| Spread | Fast Very fast Possibly fast |
| Mutation level | Moderate High Very high |
| Immune escape | Low Moderate Higher |
Risk Factors: Who Needs to Be Careful?
Though the B.A. 3.2 variant is not severe for most people but the certain groups are at higher risk.
High-Risk Groups are like,
- Elderly individuals
- People with chronic diseases (diabetes, heart issues)
- Immunocompromised individuals
- Unvaccinated population
