  • Symptoms may appear 2-14 days after exposure to the virus.
  • The most common initial symptoms are feverfatigue, and dry cough. However, nasal congestion, runny nose, conjunctivitis (red eyes), diarrhea (present in children more than adults), muscle or joint pain, chills or dizziness, and decreased or inability to smell or taste can also be present. Refer to this guide from the CDC on most commonly reported symptoms: Symptoms of Coronavirus (COVID-19).
  • Here is a video explaining the most common symptoms of COVID-19 in American Sign Language: (ASL) Symptoms Video | Covid-19

Severe symptoms can include: shortness of breath, loss of appetite, confusion, chest pain/pressure, and high fever (above  38 °C/ 100.4 °F)

  • Symptoms start out mild and worsen gradually. Symptoms can progress from mild to requiring hospital admission in a span of 5-10 days. 
  • Young individuals can be infected with the virus, but often remain asymptomatic or have mild symptoms, making them a vector that can spread the infection to those around them. 
  • Among those who develop symptoms, most (about 80%) recover from the disease without needing hospital treatment. About 15% become seriously ill and require oxygen and 5% become critically ill and need intensive care.

Long term effects of COVID can include fatigue, respiratory, cardiac, and neurological symptoms.

  • The populations that are most vulnerable are individuals over 60, immunocompromised individuals, and those with pre-existing medical conditions including, but not limited to chronic lung disease, hypertension, diabetes, obesity, heart disease, and cancer. These populations are also at the highest risk of presenting with more advanced symptoms and progressing to more severe disease.
  • According to the WHO, recovery time appears to be around two weeks for mild infections and three to six weeks for severe disease
  • According to the CDC, Multisystem Inflammatory Syndrome (MIS-C) is a possible complication experienced in COVID-19 infected children. Refer to this CDC guide for parents listing symptoms and care recommendations.
