It also attacks the nervous system.

"Increasing evidence shows that coronavriruses are not always confined to the respiratory tract and that they may also invade the central nervous system inducing neurological diseases. The infection of SARS‐CoV has been reported in the brains from both patients and experimental animals, where the brainstem was heavily infected. Furthermore, some coronaviruses have been demonstrated able to spread via a synapse‐connected route to the medullary cardiorespiratory center from the mechano‐ and chemoreceptors in the lung and lower respiratory airways. In light of the high similarity between SARS‐CoV and SARS‐CoV2, it is quite likely that the potential invasion of SARS‐CoV2 is partially responsible for the acute respiratory failure of COVID‐19 patients. Awareness of this will have important guiding significance for the prevention and treatment of the SARS‐CoV‐2‐induced respiratory failure."
