(1) An urgent need exists for effective antiviral drugs to prevent and treat SARS.(2) We were talking about it in our meeting this morning, the growing of a virus and trying to make an antiviral and all of that.(3) Specific antiviral treatment has been effective in improving the survival of the patients.(4) Ideally, patients should hold a stock of antiviral drugs for self treatment.(5) And if it is, what they can do is that they they can't give you an antiviral for this.(6) Users are advised not to open suspicious attachments and to update their antiviral signatures to block the virus.(7) Like the antiviral programs, they will always be reacting to the last exploit, not anticipating the next.(8) Harms of antiviral treatment may include drug hypersensitivity and renal impairment.(9) For infections caused by the chickenpox or herpes viruses, antiviral drugs may be prescribed if the infection is caught early.(10) Hence a natural anti-viral produced by a plant to defend itself can also be used by a human as an anti-viral.(11) Antiviral software cannot possibly keep up.
