Since first reported in December 2019, the novel RNA betacoronavirus disease (COVID‐19) has spread rapidly across the world with, as of the 3rd May 2020, 3.3 million confirmed cases with more than 230,000 deaths worldwide and more than 200 countries affected. The most common symptoms reported include dry cough, fever and fatigue with ground‐glass opacification bilaterally in the lungs on imaging and lymphopenia on haematological analysis. In severe cases the patients can develop acute respiratory distress syndrome (ARDS) or multi organ failure which can lead to death. Transmission of the virus (SARS‐CoV‐2) is via direct contact or via droplets spread by a cough or sneeze from an infected individual. The difficulty in disease detection and containment has been the long course of COVID‐19. Current evidence shows an incubation period of up to 14 days post exposure to the virus, and on average most patients first display symptoms on day five after initial exposure. More importantly, carriers are contagious even during this preceding asymptomatic incubation phase of the disease.

OBJECTIVE To evaluate models for chronic urinary incontinence (UI) in the rat. MATERIALS AND METHODS Two models were fully evaluated: one of repeated dilatation of the vagina, simulating birth trauma, the vaginal dilatation (VD) group; the other, with surgical transposition of the urethra to a vertical position, the urethral transposition (UT) group. The VD rats were evaluated by the sneeze test. When negative, vaginal dilatation was repeated in a similar way. The UT group was evaluated by observation of continuous urine leakage. The leak-point pressure (LPP) was measured at study end in all the rats. RESULTS All the VD rats had occasional negative sneeze tests and all had to be dilated again. This resulted in persistent UI on sneeze testing for the entire period. In the UT group, 12 rats leaked continuously during the whole study period; in the other four UI became less at 4, 5, 6, and 7 weeks, respectively. The LPP in the rats with UI was significantly lower than in the respective control groups. CONCLUSIONS These models permit study of chronic stress UI and continuous UI in the rat. Spontaneous recovery of continence was seen mostly in the VD group.
