With winter coming, many of us are likely to catch a cold at some point. Colds are a type of common upper respiratory infection that is caused by a virus. They are generally mild and do not require medical attention, but can still be quite uncomfortable. While there are over 200 different types of viruses that can cause a cold, the most common ones are rhinoviruses, coronaviruses, and adenoviruses.

Rhinoviruses are the most common cold-causing virus, and they are responsible for up to 35% of colds. Symptoms of a rhinovirus cold typically include a runny or stuffy nose, sneezing, sore throat, and a cough. These symptoms usually last for around a week, but can take up to two weeks to completely resolve.

Coronaviruses are the second most common cause of colds, and can be responsible for up to 20% of cases. Symptoms of a coronavirus cold can be similar to those of a rhinovirus, but may also include a fever, headache, and body aches. Coronavirus colds can last for up to two weeks, and may also lead to complications such as bronchitis or pneumonia.

Adenoviruses are responsible for around 10% of colds, and are more likely to affect children than adults. Symptoms of an adenovirus cold can include a sore throat, fever, pink eye, and a cough. Adenovirus colds can last for up to two weeks, and may also lead to complications such as pneumonia or croup.

While there are many different types of colds, they all have similar symptoms and can be treated with rest, fluids, and over-the-counter medications. Colds are generally not serious, but if symptoms last more than two weeks or are accompanied by a fever, it is important to seek medical attention.
