All 3 of these have overlapping symptoms. And COVID cases are already starting to increase in the US with the cold weather, which is just the beginning of the 2nd surge that everyone is talking about. COVID, flu, and common colds are all caused by viruses.

These tiny infectious agents can survive only by getting inside the cells of animals or humans. There are more than 200 different viruses that can cause the common cold. The most common viruses that cause common colds are rhinoviruses and different types of covid viruses. For example, COVID is caused by a specific type of covid called SARS-CoV-2. The specific virus that causes infection and how your body’s immune system responds to the virus determines the symptoms and severity of illness.
The main way that these viruses spread from person to person are through the tiny droplets that sick people propel when they cough, sneeze or talk. These droplets can fly six feet or more in the air, and they can spread the virus if they deposit on someone’s mouth or nose or they get inhaled into a person’s lungs. The novel covid, meaning SARS-CoV-2, is aerosolized and can travel up to 27 feet in aerosolized form. That is something I talk more about in a separate video Colborne transmission. With COVID, an infected person doesn’t need to show symptoms to spread the virus.
About 40% of viral transmission happens before infected people show symptoms. After people are infected, if they develop symptoms, it can be for several days or their illness duration. And about 1/3rd of people with COVID never develop symptoms. You're contagious with the common cold the entire time you have symptoms, but you’re most contagious right after you catch the infection before you have symptoms. You’re most contagious with the flu from the day before your symptoms start until about the fifth day of symptoms.
It’s important to stay home with any of these illnesses when you or your child is most infectious. Viruses also spread through physical contacts like kissing or shaking hands, or when a person touches a surface (like a desk or doorknob) that has accumulated droplets from a sick person and then touches their own eyes, mouth, or nose. Viruses can live on surfaces for hours to days, although how long they remain intact and infectious depends on the virus, the surface, and the environment.
COVID is a real wild card here. There can be no symptoms, or it can be similar to the common cold. Or it can be similar to the flu. But it can also cause loss of smell, so that is somewhat of a unique symptom. And it becomes concerning when people develop shortness of breath, which is a result of pneumonia developing. So although both flu and COVID can cause pneumonia, COVID is more likely to do so.
With COVID, it can take anywhere from two to 14 days after exposure to the virus for symptoms to appear. On average, it's 5 days. And that is if people do develop symptoms. Another unique aspect of COVID is that symptoms can start out mild or even improve temporarily and worsen. Some people continue to have fatigue and other symptoms for months after their infection, the so-called “long haulers.”
Why do some people get so sick with COVID? With COVID, the death rate ranges from 10% to 27% in people ages 85 and older but is less than 1% in those ages 54 and younger. One reason for this disparity may be differences in the aging immune system.

Oh - taking Benadryl when you have the flu is likely to put you in bed for a few hours. For me, colds usually produce a characteristic sensation in my soft palate while flu turns on the fever right away. Allergies (AFAIK) do not produce fever at all.

CONGRATULATIONS on your REWARD! So cool of you to share the unveiling of it with us! And the spot where you chose to place it, really does look good like that!!!
Congrats Dr. Mike on your KZread Award! You are providing such an essential community service!
Dr Hansen, congratulations on 100,000 subscribers. Yes, it looks great right there behind your sofa, on the shelf. Perfect color too! I want to also thank you for educating people about their lungs and conditions/diseases that can harm them. Very valuable information. This video was excellent as I had questions that you answered. I am a 10 year survivor of limited SCLC. I had a RUL lobectomy with adjunct chemo. My oxygen saturation’s stay around 97% - yes, I am truly blessed. Please take great care of yourself and make more time for rest. Blessings to you.
Congrats on the KZread award! I helped! Following your recommendations. Got the flu shot first time in decades just in case. Be well Dr. Mike.

I'm 68 and positive. I live in a nursing home in PA. THE staff love us and are taking great care of us. I got the flu shot early and my virus symptoms are like a cold but some musus. Did my flu shot lessen my symptoms and I also take Lasarton.(sorry spelling) I'm so blessed. I swear I woke up feeling something wrong. Nurses came gave me the 15 min.test and the rest is history.

For those of you confused about the loss of taste and smell with a cold, heres the difference. I had covid19 about two months ago. With a cold it feels like you lose your loss of smell from congestion and loss of smell can effect your sense of taste. With covid, my sense of smell was just gone. I had no nasal congestion at all. It was strange.
