The Stages of a Cold: What to Expect and How Symptoms Progress | UPMC Italy

Last Updated: 2 December 2024

The winter season brings with it an increased likelihood of getting cold, complicit in both frequent temperature changes and the spread of influenza, para-influenza and respiratory viruses such as adenovirus, metapneumovirus and rhinovirus. It is essential, therefore, to distinguish influenza from other respiratory viruses for proper diagnosis.

There are more than 200 viruses responsible for colds and they can cause different manifestations of the disease. In fact, symptoms vary not only according to the type of virus, but also in relation to factors such as age and health status, resulting in a different course from person to person.

Stages of the Common Cold

Symptoms of a cold evolve over the course of several days. Generally, symptoms tend to be more pronounced in the initial three days and typically decrease within approximately a week. Below is an overview of what to expect.

Incubation Period

Before symptoms become evident, the virus replicates silently within the body. During this phase, you're contagious even if unaware. Most individuals start showing symptoms only after two- or three-days following exposure to the virus.

The first 3 days: Runny nose, sore throat, and sneezing

Typically, the initial symptoms include:

  • Bone ache.
  • Nasal congestion.
  • Mild fatigue.
  • Sore throat.
  • Watery eyes.

What is the worst day of a cold?

The worst day of a common cold usually occurs around the second or third day when symptoms reach their peak. If the sore throat is intense, it's advisable to take over-the-counter pain relievers like acetaminophen and ibuprofen to alleviate discomfort. Drinking plenty of fluids can help thin out mucus, facilitating the healing process. Using decongestants in pill or spray form may be helpful, but it's essential to be cautious about excessive use, as it could worsen congestion. It's wise to limit their use to no more than three days. When in doubt, consulting a doctor who can recommend the most suitable therapy for your condition is recommended.

However, if a cough persists for over eight weeks, it's advisable to consult a doctor. A persistent cough might require further tests to rule out potential lung issues.

When to see a doctor for a cold

In certain cases, a cold can progress to more serious conditions like pneumonia, especially in individuals with a weakened immune system and the elderly. If symptoms such as chest pain, high fever, difficulty breathing, or vomiting occur, it's crucial to contact a doctor immediately. Sometimes, a cough can persist for many weeks. If this is the sole symptom and the cough seems to improve over time, it's usually not a cause for concern.

However, if a cough persists for over eight weeks, it's necessary to consult a doctor. A persistent cough might require tests to exclude potential lung problems.
