New COVID Variant “Cicada” Under Global Watch
A new COVID-19 variant named BA.3.2, informally called “Cicada,” is being detected in different parts of the world. Health agencies have noted that it existed at low levels for a long time before becoming more visible. The name reflects how it stayed hidden for months before spreading more widely.
Origin and Spread Timeline
The first known case of this variant was reported in South Africa in November 2024. Its spread became more noticeable around September 2025. In the United States, it was first seen in a traveller and later began appearing in more cases in early 2026. So far, it has been identified in more than 20 countries, especially in parts of Europe.
Monitoring and Surveillance Efforts
Global health agencies are closely tracking BA.3.2 and have placed it in the “variant under monitoring” category. This means it is being watched carefully but is not yet considered highly dangerous. Scientists have also detected it through wastewater surveillance, which helps identify hidden spread in communities.
Mutations and Spread Potential
The Cicada variant has around 70 to 75 mutations, which makes it quite different from earlier strains. These changes may help it spread more easily or avoid some immunity from past infections or vaccines. However, experts are still studying whether it will become a dominant variant.
Exam-Focused Points
-
Variant name: BA.3.2 (Cicada)
-
First detected: South Africa, November 2024
-
Category: Variant under monitoring
-
Mutations: Around 70–75
-
Detection method: Wastewater surveillance
Symptoms and Vaccine Protection
The symptoms are similar to earlier COVID-19 variants. Common signs include cough, fever, fatigue, sore throat, headache, and loss of taste or smell. Some patients may feel strong throat pain. There is no clear evidence that it causes more severe illness. Vaccines may be less effective in preventing infection, but they still provide strong protection against serious disease.
