Measles is contagious, while urticaria (hives) is generally not. It is recommended to wash hands promptly and wear a mask after contact with a measles patient, while urticaria patients only need to pay attention to daily care. The following are specific instructions:
1. Measles is highly contagious.
Measles is spread through droplets from coughs and sneezes. Unvaccinated or previously uninfected individuals are more susceptible to infection. It is highly contagious during the initial stages of the illness and for several days after the rash appears, requiring isolation and treatment.
2. Urticaria is usually not contagious.
Urticaria is mostly caused by allergies, infections, or physical irritants, and manifests as wheals and itching on the skin. It is an internal bodily reaction and is not transmitted to others through contact or air.
3. Daily Precautions
If someone around you has measles, avoid close contact and ensure good ventilation and disinfection. For urticaria, it is recommended to record possible triggering factors such as food and environmental changes, and wear loose clothing to reduce skin irritation.
In summary, distinguishing between the contagiousness of the two will help in responding appropriately. If you experience measles-like symptoms (such as fever and rash), please seek medical attention promptly and inform the doctor of your contact history. If you experience recurrent urticaria, consult a doctor to find the cause and avoid self-medicating.
