Infectious disease

Antiviral strategies against COVID-19 broadly fall into two groups: those that target the virus and those that target the host factors that are essential for virus replication.

Tipped off by artificial intelligence, a research team is testing whether a rheumatoid arthritis drug could be repurposed as a COVID-19 treatment.

Researchers at A*STAR have uncovered a new role for a subset of immune cells in HIV infection and transmission.

Targeted mutagenesis is being used to create live-attenuated vaccines against the chikungunya virus.

A*STAR researchers have identified four peptide sequences that distinguish the Zika virus from other flaviviruses, with implications for diagnostics and vaccine development.

The antiviral protein Viperin keeps immune cells in check to prevent joint swelling during chikungunya virus infection.
