Viruses in the nose can be cleansed out
During the clinical study, medical investigators determined that cold and flu viruses could be removed by performing an effective nasal irrigation three times a day. On the day 1 office visit, or baseline visit, the patients had not yet performed nasal irrigation. Their nasal secretions tested positive for an influenza virus. After performing nasal irrigation three times a day for three days, all patients, who had previously tested influenza virus positive, had nasal secretions that were virus negative by the day 4 office visit.
Clinically, these patients had basically recovered from the viral infection. During the next office visit on day 8, all those patients again tested negative for the virus in their nasal secretions, and all patients were clinically fully recovered.
Because the patients could not come to the clinic every day to test for viruses in their nasal secretions, there is a chance that these viruses were cleaned out even before the day 4 office visit. This indicates that timely performing nasal irrigation with the NasalCare Irrigation Kit may have the similar efficacy to the well-known antiviral drugs oseltamivir and Tamiflu, since both of these drugs can reduce the duration by more than one day. You need to take either drug for five days, and some side effects were reported.
Drug resistance to theses anti-viral drugs also occurs quickly. Using NasalCare to perform nasal irrigation will not generate drug resistance, and there are no noticeable adverse effects. The limitation of performing nasal irrigation is unable to treat the lung infection. For the treatment of any lung infection, you need a physician to help you.
To know more of the why, the medical investigators also determined the concentration of the cold/flu virus receptors in the nasal secretions. These virus receptors are critical for the virus to be able to enter into the epithelial cells to grow (replicate). If these receptors become unavailable for the viruses, the newly released cold viruses then cannot attach to the epithelial cells in the nasal cavities, then the repeat infection by the cold viruses will be inhibited. The study reported that the concentrations of the virus receptors in the nasal secretions among all groups were very similar before the study treatment. However, after performing nasal irrigation, the concentrations of the virus receptors in the nasal secretion of the patients were significantly lower than those from patients in the control (comparison) group.
