There is a wealth of data available to track seasonal flu activity, including the CDC and World Health Organization websites, as well as local public health offices. See the Resources We Love section below. COVID and the flu are caused by different viruses. One doesn't cause the other, though it is possible to contract both at the same time.
Diagnostic testing can confirm which virus you're dealing with, notes the CDC. Some conditions are related to colds and the flu, meaning you may develop them after being sick, or they may make you more susceptible to catching a virus. These include:. National Vaccine Information Center This independent nonprofit provides extensive information on vaccine science and includes research on the effectiveness of specific vaccines.
Best Information for Colds Mayo Clinic This website offers information that will help you determine whether your symptoms are related to a cold and when you need to see a doctor, and offers preventive tips that may help you avoid getting sick.
National Library of Medicine The common cold section of the MedlinePlus website provides comprehensive information on the causes and symptoms of the common cold, as well as links to information on how to determine whether you are suffering from a cold, the flu, or an allergy.
Best Resources for Parents Healthy Children This American Academy of Pediatrics site focuses on how to identify flu symptoms in your children, the potential treatments, and preventive tips. KidsHealth — Colds The KidsHealth site also has a page dedicated to providing general information on common cold treatments for kids and potential complications.

Like the A virus, illness caused by influenza B may persist for a week or two. Type C flu, which affects only humans, is much milder than types A and B. It typically causes mild respiratory illnesses and it is not known to have caused any seasonal flu epidemics. Most people who contract influenza C will experience symptoms similar to those of a cold.
Even so, influenza C can become serious in:. In healthy people, influenza C usually goes away on its own in three to seven days. Influenza C outbreaks can sometimes co-exist with influenza A pandemics. In , influenza D virus was isolated from swine and cattle. It's been reported in multiple countries, suggesting worldwide distribution. To date, the influenza D virus has not demonstrated the ability to be passed from animals to humans, although scientists suggest that such a jump may be possible.
In the spring of , scientists discovered a new influenza A virus in Mexico and named H1N1 also known as swine flu. H1N1 influenza is a combination of human, swine, and bird flu. It became the first flu pandemic the world had seen in more than 40 years. It's technically an influenza A virus but is so mutated that it's not the same as the influenza A that causes seasonal flu.
Research suggests that the influenza H1N1 may not be as new as some have suggested. Genetic analyses have linked it to the flu pandemic which killed over 50 million people, including , in the United States. H5N1 is the strain of influenza known as the bird or avian flu. Typically, it's transmitted between birds, but it can be passed from bird to human.
It does not appear to spread from person to person. When it does infect humans, bird flu is associated with very serious illness, multi-organ failure, and high death rates. Although the risk of contracting bird flu is low, doctors have grave concerns about the potential of H5N1 to mutate and cause a worldwide pandemic.
Increasing rates of H5N1 infections in Egypt suggest that widespread human-to-human transmission may be possible. What many call the stomach flu is actually not flu at all. Rather, it is gastroenteritis , which is in no way related to the influenza virus. Influenza is a respiratory illness. While it can cause vomiting and diarrhea, especially in children, it is always accompanied by respiratory symptoms.
Flu vaccines are customized each year to protect against the strains researchers believe are most likely to circulate among humans that season. The vaccine only protects you from the specific strains it contains. It doesn't contain C or D viruses, and it doesn't protect against other viral illnesses with similar symptoms, which often spread during flu season.
The Centers for Disease Control and Prevention CDC recommends that everyone over six months old be vaccinated against the flu unless certain health problems prevent it. Looking to avoid getting the flu?

Updated November 18, Influenza C and D viruses package eight organized ribonucleoprotein complexes. J Virol. Adaptation of avian influenza virus to a swine host. Virus Evol. Origin of the pandemic H1N1 influenza A virus as studied by codon usage patterns and phylogenetic analysis. The approach uses the following components:. Getting a flu vaccine can protect against these viruses as well as additional flu viruses that are antigenically similar to the viruses used to make the vaccine.
Seasonal flu vaccines do not protect against influenza C or D viruses or against zoonotic animal-origin flu viruses that can cause human infections, such as variant or avian flu viruses. In addition, flu vaccines will NOT protect against infection and illness caused by other viruses that also can cause influenza-like symptoms.
There are many other viruses besides influenza that can result in influenza-like illness ILI that spread during flu season. To receive weekly email updates about Seasonal Flu, enter your email address:. Skip directly to site content Skip directly to page options Skip directly to A-Z link.
