When it comes to distinguishing between allergies and a cold, especially during the transitional seasons, it's essential to understand the symptoms and their characteristics. Based on your description, it seems you are experiencing nasal symptoms that have progressed from mild discomfort to significant nasal discharge. Let's break down your questions.

1. Is this an allergy or a cold?
The symptoms you describe—such as a runny nose that resembles a faucet and the presence of yellow mucus—can be indicative of both allergies and a cold, but there are key differences. Allergies typically cause clear, watery nasal discharge, sneezing, and itchy eyes, and they can occur suddenly upon exposure to allergens like pollen, dust, or pet dander. On the other hand, a cold, which is caused by a viral infection, often starts with a sore throat and may progress to nasal congestion, a runny nose, and sometimes a cough. The presence of yellow mucus can suggest a secondary bacterial infection, which is more common with colds than with allergies.

Given that your symptoms have developed over a few weeks, it is possible that you may have initially experienced an allergic reaction that later led to a cold or a sinus infection. If your symptoms persist or worsen, it would be wise to consult a healthcare provider for a definitive diagnosis.

2. Are there any infectious diseases with a long incubation period of 2-3 weeks?
Yes, several infectious diseases can have a long incubation period, ranging from a few days to several weeks. For instance, certain viral infections, such as mononucleosis (caused by the Epstein-Barr virus), can have an incubation period of 4 to 6 weeks, but symptoms may not appear until later. Other illnesses, like some types of hepatitis or even certain bacterial infections, can also have prolonged incubation periods. However, these are less common in the context of typical seasonal illnesses like colds or flu.

In conclusion, your symptoms could be due to either allergies or a cold, and the yellow nasal discharge suggests that it may be more than just allergies. If you experience additional symptoms such as fever, facial pain, or persistent cough, it would be prudent to seek medical attention. A healthcare professional can perform a thorough evaluation, possibly including allergy testing or a nasal swab, to determine the exact cause of your symptoms and recommend appropriate treatment.

In the meantime, consider some self-care measures. For allergy relief, over-the-counter antihistamines can help alleviate symptoms. If you suspect a cold, staying hydrated, resting, and using saline nasal sprays can provide comfort. If you have any underlying conditions, such as asthma, ensure that your management plan is up to date, especially during these transitional seasons when symptoms can be exacerbated.
