1. Point mutation: This type of mutation involves a change in a single nucleotide base in the viral genome. For example, a point mutation in the influenza virus can lead to resistance to antiviral drugs such as oseltamivir.
2. Insertion or deletion: This type of mutation involves the addition or removal of nucleotide bases in the viral genome. For example, an insertion mutation in the HIV virus can lead to changes in the viral envelope protein, affecting its ability to infect host cells.
3. Reassortment: This type of mutation occurs when two different strains of a virus infect the same host cell and exchange genetic material. For example, reassortment in the influenza virus can lead to the emergence of new strains with pandemic potential.
4. Recombination: This type of mutation involves the exchange of genetic material between different strains of the same virus. For example, recombination in the hepatitis C virus can lead to the emergence of drug-resistant strains.
5. Frame-shift mutation: This type of mutation occurs when nucleotide bases are inserted or deleted in multiples of one or two, causing a shift in the reading frame of the viral genome. For example, a frame-shift mutation in the Ebola virus can lead to changes in viral protein expression and virulence.
