Men infected with neoguana may experience a decline in lung function, cardiac complications, and even a male reproductive system as sequelae, and further research is needed to determine the exact outcome. 1. Decreased lung function: Patients with neocollins usually have prolonged and persistent dyspnea and fatigue after discharge from the hospital, and neocollins can cause interstitial lung damage resulting in abnormal non-carbon monoxide diffusion capacity. 2. Cardiac complications: New crown virus will attack the heart leading to myocardial damage, hypoxia, hypotension, increased inflammation, etc., which may lead to hypertension, atherosclerosis and heart failure and other cardiac complications. 3. Reproductive system: Some studies have indicated that Neocollins can attack male testicular cells, which may cause shrinkage of male testicles and hypogonadism. There is a certain chance of sequelae after infection with New Crown. If infected, it should be treated actively, and early treatment can prevent the occurrence of sequelae. However, given that the new coronavirus is a new virus, there are still insufficient reports on the sequelae, and the details still need to be studied.
