Many patients with confirmed COVID-19 have developed a fever and/or symptoms of acute respiratory illness (e.g., cough, difficulty breathing). However, limited information is currently available to characterize the full spectrum of a clinical illness associated with COVID-19. Based on what is known about the virus that causes COVID-19, signs, and symptoms may appear at any time from 2 to 14 days after exposure to the virus. Based on preliminary data, the median incubation period is approximately 5 days but may range 2-14 days. See our infographic for more information.
Public health officials have identified cases of COVID-19 infection throughout the world, including the United States, which may pose risks for public health. Please check the CDC webpage for the most up to date information.
