A sign is an objective indication of a disease or other medical condition. It is something that can be observed by another person, such as a doctor or nurse. Signs can be seen, heard, smelled, felt, or tasted.

Differences Between Signs and Symptoms
The main difference between signs and symptoms is that signs are objective and symptoms are subjective. This means that signs can be observed by another person, while symptoms cannot.
Another difference between signs and symptoms is that signs are often more specific to a particular disease or condition, while symptoms can be more general. For example, a rash can be a sign of many different diseases, such as measles, chickenpox, or eczema. However, a fever is a more general symptom that can be caused by many different diseases, such as the flu, a cold, or an infection.
Importance of Distinguishing Between Signs and Symptoms
It is important to be able to distinguish between signs and symptoms because it can help doctors to diagnose diseases more accurately. For example, if a patient presents with a rash and a fever, the doctor will be able to narrow down the list of possible diagnoses by considering the signs and symptoms together. The rash may be a sign of measles, chickenpox, or eczema, but the fever suggests that the patient has an infection.
Conclusion

Signs are objective indications of a disease or condition, while symptoms are subjective experiences of a disease or condition. It is important to be able to distinguish between signs and symptoms because it can help doctors to diagnose diseases more accurately.
