A New COVID‑19 Variant BA.3.2

In a recent article from The Conversation, Prof. Kyle B. Enfield, a pulmonary and critical care doctor, discusses a new COVID-19 variant called BA.3.2, nicknamed Cicada. He explains that it has begun spreading quickly across the United States after going largely unnoticed for over a year. The topic has also been covered by TIME magazine reporter Alice Park.

Here are the key highlights from these two sources:

Key Highlights

  • A variant with a fitting nickname. Writing in The Conversation, Dr. Enfield of the University of Virginia explains that BA.3.2 is a descendant of the Omicron variant, which first appeared in late 2021. According to TIME, the variant is nicknamed “Cicada” because, like the insect, it stayed dormant for a period before reappearing.
  • A trail that began in Africa. Dr. Enfield reports that researchers first identified BA.3.2 in November 2024 in Africa. The strain had reached 23 countries by February 2026, and the first U.S. case was detected in a traveler in June 2025. Since then, it has been found in patients and wastewater systems across 29 states. However, Dr. Enfield notes that reporting from wastewater systems to the CDC has declined since 2022.
  • Many mutations, but no stronger punch. TIME reports that Cicada carries 70 to 75 mutations in the spike protein, the part of the virus the immune system recognizes. Dr. Enfield says there is no evidence so far that BA.3.2 causes more severe illness than earlier strains. However, because the variant looks different, current vaccines may offer weaker protection, which could lead to more cases. TIME adds that since Cicada is still part of the Omicron family, updated vaccines targeting strains such as JN.1 should still provide protection.
  • Simple steps still matter. Dr. Enfield recommends basic precautions such as washing hands often, staying home when unwell, spending time outdoors, and wearing a high quality N95 or KN95 mask when needed. He also notes that about 3 out of 100 COVID cases still lead to long COVID. People with chronic conditions should speak with a trusted clinician about their risk.

According to Dr. Enfield and Park, the Cicada variant is worth monitoring but not a cause for panic. Its many mutations and quiet spread make it a challenge for researchers, yet vaccines and everyday precautions still offer protection. The shared message is to stay aware without alarm.
