Detailed answer

It is generally safe to use face masks if you have a weak immune system or a history of immunodeficiency. However, it is important to consult with your healthcare provider to determine the appropriate type of face mask and any additional precautions you may need to take. Face masks can provide some level of protection against airborne particles and help reduce the risk of contracting various infections. However, it's important to note that face masks alone may not provide complete protection, and it is essential to follow other preventive measures like regular hand hygiene, social distancing, and avoiding crowded places. Your healthcare provider can help assess your specific situation and provide personalized advice on using face masks effectively while considering your unique needs and medical history.
