Summary Introduction
To explain: How neuraminidase inhibitor drug Oseltamivir (Tamiflu) helps in prevention of flu or reduces disease course of flu in a flu patient.
Introduction: An antiviral drug, Oseltamivir (Tamiflu), is recommended for patients infected by the influenza virus. Influenza virus is an RNA virus belonging to the family of Orthomyxoviridae. This virus produces flu with symptoms such as fever, sore throat, and coughing. Oseltamivir is a drug that inhibits the enzyme neuraminidase.

More than one answer may be correct. The graph relating to the information is included below. The above graph is looking at the relative entry of SARS-CoV2 isolated spike proteins into human cells in culture at two times points: before introduction of the virus to the cell culture (0 minute) and 5 minutes after introduction of the virus to the cell culture. CHC stands for "clathrin heavy chain" and siRNA stands for small interfering RNA, which is often used in experiments as an easy method to stop expression of a certain gene. So in this case, the CHC siRNA would stop cellular production of CHC. The control siRNA introduces a small RNA fragment that does not match any gene as a negative control. Imagine that the experiment was then allowed to run for 500 minutes in addition to five minutes? How would the relative uptake of the spike protein into the control siRNA cells compare after 500 min to the 5 minute treatment?

From the above figure, you can conclude what about the process that allows the SARS CoV-2 virus entry into the cell?
