Rimantadine inhibits influenza activity by binding to amino acids in the M2 transmembrane channel and blocking proton transport across the M2 channel. [7] Rimantadine is believed to inhibit influenza's viral replication, possibly by preventing the uncoating of the virus's protective shells, which are the envelope and capsid. The M2 channel is ...
Treatments for influenza include a range of medications and therapies that are used in response to disease influenza. Treatments may either directly target the influenza virus itself; or instead they may just offer relief to symptoms of the disease, while the body's own immune system works to recover from infection.

Whereas DIPs had been proposed as potential therapeutics that would act via stimulation of the immune system [20] – a concept [8] [26] tested in influenza with mixed results [9] [10] – the TIP R 0 >1 mechanism of action was first proposed in 2003 [3] with the term “TIP” and the unique benefits of the R 0 >1 mechanism shown in 2011.

Viral neuraminidases are essential for influenza reproduction, facilitating viral budding from the host cell. Oseltamivir (Tamiflu), zanamivir (Relenza), laninamivir (Inavir), and peramivir belong to this class. Unlike the M2 inhibitors, which work only against the influenza A virus, NAIs act against both influenza A and influenza B. [1] [2] [3 ...
Surveillance and preventative activities are increasingly a priority for hospital staff. The Study on the Efficacy of Nosocomial Infection Control (SENIC) project by the U.S. CDC found in the 1970s that hospitals reduced their nosocomial infection rates by approximately 32 per cent by focusing on surveillance activities and prevention efforts.

Therapeutic vaccines are a new form of vaccines that are mostly being used for viral infections and various types of cancers. A therapeutic vaccine helps an immune system to recognise a foreign agent such as cancerous cells or a virus. The specific type of therapeutic vaccines include antigen vaccines. In case of antigen vaccines, the body is ...
Influenza hemagglutinin (HA) or haemagglutinin [p] (British English) is a homotrimeric glycoprotein found on the surface of influenza viruses and is integral to its infectivity. Hemagglutinin is a class I fusion protein, [1] [2] having multifunctional activity as both an attachment factor and membrane fusion protein.
Oseltamivir, sold under the brand name Tamiflu among others, is an antiviral medication used to treat and prevent influenza A and influenza B, viruses that cause the flu. [5] Many medical organizations recommend it in people who have complications or are at high risk of complications within 48 hours of first symptoms of infection. [ 6 ]
