How would you write hypothesis for research question using a wilcoxon test in statistics?

Researchers want to test a new antiviral drug to reduce the number of symptoms experienced by the virus. The participants will rate their symptoms before and after taking Statistivox. Does the anti-viral medication affect virus symptoms?

I have the following and am unsure if it is correct need guidance:

H₀: Statistivir does reduce the number of virus symptoms H₁^: Statistivir does not reduce the number of virus symptoms

Thanks
