Typically, vaccinated people are either asymptomatic or have very mild symptoms if they contract the delta variant. Their symptoms are more like those of a common cold, such as cough, fever or headache, with the addition of significant loss of smell.
Delta is believed to be more than twice as contagious as previous variants, and studies have shown that it may be more likely than the original virus to put infected people in the hospital.
All of the variants, including delta and omicron, cause similar COVID-19 symptoms, including cough, fever and fatigue. There is some evidence that fewer people with omicron lose their taste and smell. Omicron is also less likely to cause severe disease such as pneumonia that may require treatment in the hospital.
