New COVID Variant BA.3.2: Symptoms, Risk & What We Know So Far

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
