Cold and flu are two contagious respiratory infections that happen due to virus. How long you take to pass on the infection to another person tends to vary. Here, we will help you determine how long is the flu contagious and how can you quickly heal without spreading it.
Most people who have a common cold or flu don’t visit a doctor. It isn’t deadly or fatal but can be chronic if not cured. It is, however, difficult to track how people have the illness as it varies from one to another. If you know you have caught a cold or flu, you can find ways to prevent the respiratory illness for someone else. But it is first important to cure yourself.
How long is a common cold contagious?
Cold spreads when symptoms like sneezing still happen. Most people spread a common cold due to sneezing, touching, coughing, or contaminated surfaces. This means that people are more contagious once the symptoms become obvious. However, many can be contagious before realizing they have a cold.
When your immune system is weak and lets viruses take over, you can have a common cold. You soon find the symptoms improve and the risk of spreading the illness reduces. But you can still be infectious and not know how long is the flu contagious. An average cold lasts for around 10 days, so you can be contagious during that period.
A seasonal cold is a common respiratory problem that many of us have during a climate change. As per the CDC, millions of people in America catch a cold every year. There are different viral strains that cause such symptoms of cold, like rhinoviruses, coronaviruses, and adenoviruses.
The viruses keep evolving all the time to adapt to the environment and live in the human immune system. This is also the reason why there is no definitive cure available for a common cold.
How long is the flu contagious?
The symptoms of flu also last for around 10 days depending on an individual. A person can spread the flu from a day before the symptoms start to show up. It can last for seven days from the time you fall ill.
Influenza virus is pretty contagious and can infect people of every age group. The severity of the infection differs from person to person. For some people, the condition can be life-threatening. For example, babies or elderly people with low immunity can face this problem.
Viruses tend to spread due to a process called viral shedding. When a virus finished the replication cycle within one cell, it releases new ones. The new viruses can infect more cells and your body can transmit that to other people.
The viruses can exit from the body in many ways. One common example is by mixing with mucus and saliva. Such substances find a way to get back into the environment through sneezing, coughing, and more.
According to the Pediatric Infectious Disease Journal, kids have a longer timespan of viral shedding before the onset of symptoms while adults have less. Kids aged between 0 and 5 usually have the longest period of viral shedding even after their flu is cured.
The symptoms between cold and flu are what brings in a major difference. Flu is more serious than cold. It tends to affect the entire body, while cold only causes symptoms in the upper airway.
Like other types of viruses, flu is constantly changing and evolving. Their body rarely deals with the same kind of flu viruses twice. But this can also lead to some people contracting the flu once every year.
How to prevent spreading?
Rather than finding out only about how long is the flu contagious, know how you can prevent it in the first place. To start with, you need to maintain hand hygiene to limit the spread of both the flu and cold. The most important factor is how it reduces the spread of viral infection and create healthy habits during the illness.
For example, you must eat a lot of healthy food, have water, get enough rest, and more. These practices will reduce symptoms and the illness seem bearable. When symptoms are showing, you can help protect other people from having the illness. Some of the simple ways to do so are:
1. Covering a cough
You should use a handkerchief to sneeze or cough. Cover your nose and mouth with a tissue if you don’t carry a hanky or use the elbow of your sleeves. The spray of the mucus from your saliva includes viruses that can spread the infection.
2. Throw the tissues
Once the tissue is dirty, you must discard it immediately. Use a new tissue every time you need to cough or sneeze. Make sure you wash your hands to keep them clean all the time.
3. Wash frequently
Keeping yourself neat and clean can help you fight infectious viruses that can spread. Washing your hands, taking a bath, using hand sanitizers, can keep you clean all the time. You should try to avoid direct contact with people or not touch public items when you have flu.
If the symptoms become tough to manage, you should stay at home for a while. Take rest until you feel better and find your symptoms go down. It helps you heal quickly and keeps people away from the contagious flu.

As per a CDC report, vaccination reduces the risk of the contracting flu by 40 to 60 percent. It is suitable for a type of virus that keeps circulating.
There are many more factors that can stop the effectiveness of a vaccine. But CDC recommends us to take a vaccine as it is the best way to prevent flu.
Myths about having a flu
There are some people who think that taking a flu vaccine can cause flu. But that is a complete myth. After taking an injection, some people experience pain in the arm on the following day. It is a type of immune reaction from the shot and resolves within a couple of days.
Flu shots take around 15 days to become fully effective. There are some people who are already infected when they take the vaccine. In such a case, you shouldn’t mistake the vaccine with the effect.
Manufacturers who produce a flu vaccine use inactive viruses or other viral components as opposed to ‘live’ virus. This is the reason why you cannot have the flu from a flu shot. In many cases, treating the symptoms of flu in the right way can help you heal quickly. You need to work on that too.
