Influenza flu and the common cold are both types of upper respiratory infections URIs.
Both are caused by viruses. But the flu is not the same as the common cold. Flu symptoms are usually much worse than a cold. The flu usually comes on suddenly and lasts longer. The symptoms usually are the worst for the first 3 or 4 days. In most healthy people, the flu will go away in 7 to 10 days. These particles can land in the mouths or noses of people who are nearby and possibly be inhaled into the lungs.
In some circumstances, such as indoor settings with poor ventilation, small particles might be spread further than 6 feet and cause infections.
Although most spread is by inhalation, it may be possible that a person can get infected by touching for example, shaking hands with someone who has the virus on their hands or by touching a surface or object that has virus on it, and then touching their own mouth, nose, or eyes. Both flu viruses and the virus that causes COVID can be spread to others by people before they begin showing symptoms; by people with very mild symptoms; and by people who never experience symptoms asymptomatic people.
This means the virus that causes COVID can quickly and easily spread to a lot of people and result in continual spreading among people as time progresses. Those at highest risk include:. Most people who get flu will recover on their own in a few days to two weeks, but some people will experience severe complications , requiring hospitalization.
Some of these complications are listed above. People at higher risk of complications or who have been hospitalized for COVID or flu should receive supportive medical care to help relieve symptoms and complications.
Prescription influenza antiviral drugs are FDA-approved to treat flu. People who are hospitalized with flu or who are at increased risk of complications and have flu symptoms are recommended to be treated with antiviral drugs as soon as possible after illness onset.
FDA has issued emergency use authorizations external icon EUAs to allow healthcare providers to use investigational products that are not yet approved, or that are approved for other uses, to treat patients with COVID if certain legal requirements are met external icon. There are multiple FDA-licensed influenza vaccines produced annually to protect against the 4 flu viruses that scientists expect will circulate each year. Both can spread from person to person, especially when in close contact.
People can be infected by both at the same time. Sharieff says. People tend to develop flu symptoms one to four days after infection. But there are many other possible signs and symptoms.
The U. These viruses spread in similar ways and cause many of the same signs and symptoms. However, there are a few differences. There's no cure for the common cold. Treatment may include pain relievers and over-the-counter cold remedies, such as decongestants. Most people recover from a common cold in three to 10 days, although some colds may last as long as two or three weeks.
Seasonal allergies are immune system responses triggered by exposure to allergens, such as seasonal tree or grass pollens. COVID and seasonal allergies cause many of the same signs and symptoms.
However, there are some differences. Also, while COVID can cause shortness of breath or difficulty breathing, seasonal allergies don't usually cause these symptoms unless you have a respiratory condition such as asthma that can be triggered by pollen exposure. Treatment of seasonal allergies may include over-the-counter or prescription antihistamines, nasal steroid sprays and decongestants, and avoidance of exposure to allergens where possible.
Seasonal allergies may last several weeks. COVID and the flu are both contagious respiratory diseases caused by viruses. These viruses spread in similar ways. COVID and the flu cause similar symptoms. The diseases can also cause no symptoms or mild or severe symptoms.
