Neuraminidase inhibitors (NAIs), such as oseltamivir and zanamivir, serve as the primary treatment for influenza virus infection. NAI-resistant influenza A(H1N1) strains were widespread during the 2008–09 influenza season, especially in Japan, where 100% of the strains were resistant to oseltamivir. 1 Baranovich T Saito R Suzuki Y et al.

The SARS-CoV-2 omicron variant XBB sublineage, a BA.2.10.1–BA.2.75 recombinant classified as variant under monitoring by WHO, has been found in 35 countries, 1 WHO COVID-19 weekly epidemiological update - 26 October 2022. and has become the dominant strain in Singapore. There is early evidence suggesting that XBB might be associated with a higher risk of reinfection. 2 WHO TAG-VE statement on omicron sublineages BQ.1 and XBB. 2022.
