A NEW Covid-19 Omicron sub-variant is spreading across Ireland and is the most infectious strain yet. If you have symptoms take a PCR test and isolate at home until you receive a negative result. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. As I previously reported, omicron subvariants have a shorter incubation period, which is why the symptoms may appear earlier.

In the age group of 20-50 years, significant severity is not expected. According to the World Health Organization (WHO), nearly 99% of viral DNA submitted to the global GISAID database as of 25 January were identified as this sub-variant. Whilst the impact of these variants is uncertain, the variant classification system aims to identify potential risk as early as possible. However, the preliminary data showed effectiveness against the new variant appears to increase considerably in the early period after a booster dose, providing around 70% to 75% protection against symptomatic infection.
