New COVID-19 Variant ‘Cicada’ Spreads Across 23 Countries, Experts Flag Potential Risk for Children

London

A new and highly mutated COVID-19 variant, named “Cicada” (BA.3.2), has been placed under monitoring by the World Health Organization as it spreads across 23 countries, including the United States, the United Kingdom, Hong Kong, and Mozambique. While experts say the variant does not appear to be more deadly than previous strains, early data suggests children may be more susceptible to infection.

Why the Name ‘Cicada’?

The variant derives its name from the cicada insect, known for remaining dormant underground for long periods before emerging suddenly. Similarly, the BA.3.2 variant was first detected in November 2024 but remained largely inactive for months before witnessing a recent surge in cases.

Why Are Children More at Risk?

According to Professor Ravindra Gupta from Cambridge, children may be more vulnerable because their immune systems are less mature compared to adults. Over the past few years, adults have developed stronger immune memory through repeated infections and vaccinations. In contrast, children have had less exposure, making it easier for a new variant like Cicada to evade their immune defenses.

Symptoms Similar to Previous Variants

Health experts indicate that symptoms of the Cicada variant are largely consistent with earlier COVID-19 strains. These include fever, cough, sore throat, congestion, fatigue, headache, breathing difficulties, and diarrhea.

Epidemiologist Paul Hunter noted that there is currently no evidence suggesting that the variant causes more severe illness than previous ones.

Effectiveness of Vaccines

Virologist Ian Jones stated that while mutations in the Cicada variant may help it partially evade antibodies, existing vaccines are still effective in reducing the risk of severe disease and hospitalization. Infections may still occur, but they are likely to remain mild in most cases.

Experts Urge Caution, Not Panic

The World Health Organization and other experts have assessed the public health risk as currently low. Healthy children are unlikely to face severe complications, but those with pre-existing heart or lung conditions should take extra precautions.

Experts emphasize that COVID-19 has now become part of routine infectious diseases, and staying informed, maintaining hygiene, and taking booster doses when necessary remain the best protective measures.
