Yes one can spread without any symptoma,Asymptomatic COVID-19 positive means a person has been tested positive but has no symptoms, and does not go on to develop symptoms, Many people with COVID-19 experience only mild symptoms, especially in early stages of the disease. "It is possible to catch COVID-19 from someone who has just a mild cough and does not feel ill. Some reports have indicated that people with no symptoms can transmit the virus. I would suggest you to stay safe and keep distancing, no need to go outside without a reason. If you nwed to go outside then always use mask and carry sanitizer with you, keep distance atleast 1.5 m with anyone.Take care.
