Understanding 'Cicada COVID': Risks and Precautions

     Getting to know the new COVID variant “Cicada” (or BA.3.2), the latest sub-variant of Omicron that the World Health Organization (WHO) has designated as a “Variant Under Monitoring” (VUMs) due to numerous mutations in the spike protein, which may affect immune evasion.

What is Cicada COVID... Does it come from insects?

     The name "Cicada" is just a nickname used for the BA.3.2 variant for easy international recognition. It is not related to insects and is not transmitted through insects in any way.

Is it different or more severe than previous variants?

• Mutations: More than 50 genetic changes have been found, especially in the spike protein area, which helps the virus enter human cells and evade the immune system more effectively.
• Severity: From laboratory data, "there is no evidence yet that it causes increased severity" compared to other Omicron variants currently circulating. Its replication and transmission behavior remain at similar levels.

Has it reached Thailand yet... Anything to worry about?

     Based on current surveillance and genomic sequencing, "no reports of the Cicada variant have been found in Thailand yet." It is mostly detected in small proportions (about 5-8%) in some countries such as South Africa, Australia, and the United States, so it is not the dominant variant globally at this time.

How to prepare... Is there a vaccine yet?

Currently, there is no vaccine specifically produced for the Cicada variant. However, having basic immunity still helps reduce the severity of the disease. The important thing is to take care of yourself according to familiar measures:

• Wash your hands frequently and avoid crowded places.
• Wear a mask when in high-risk areas or poorly ventilated spaces.

Monitor for unusual symptoms such as fever, cough, or difficulty breathing. If symptoms occur, perform an ATK test and consult a doctor for an accurate diagnosis.
