    Study Notes

    General Characteristics of Viruses

    • Viruses contain a single type of nucleic acid (DNA or RNA) and a protein coat, sometimes enclosed by an envelope composed of lipids, proteins, and carbohydrates.
    • Viruses multiply by using the host cell's synthesizing machinery to cause the synthesis of specialized elements that can transfer the viral nucleic acid to other cells.

    Herpes Simplex Virus

    • Can cause genital herpes, mucocutaneous herpes, herpes simplex encephalitis, herpes simplex keratitis, and herpes zoster (also known as chickenpox).
    • Type-1 virus causes herpes simplex encephalitis.

    Cytomegalovirus (CMV)

    • Can cause retinitis in patients with AIDS.

    Amantadine

    • Used for prophylaxis and treatment of influenza A2.
    • Reduces fever, congestion, cough, and promotes quicker recovery.
    • Also used to treat Parkinsonism.

    Antiretroviral Therapy (ART)

    • Zidovudine is used in combination with at least two other ARV drugs to treat HIV-infected patients.
    • Used for prevention of perinatal HIV-1 infection.
    • Tenofovir is a nucleotide analogue with a good tolerability profile, making it a first-line regimen option.
    • Tenofovir-containing regimens are effective and less toxic than other first-line regimens.

    Integrase Inhibitors

    • Examples include Dolutegravir, Raltegravir, Bictegravir, and Elvitegravir.

    Antimicrobial Resistance (AMR)

    • No specific information provided.
