Both are caused by viruses - the common cold family of viruses (rhinoviruses and coranaviruses), and the influenza family of viruses (Orthomyxoviridae).
Both viruses are primarily via airborne droplet, but transmission via infected surfaces is also possible (but much less likely). They tend to enter through compromised mucus membrane tissue, as is common in dried-out nasal passages, or through inhalation. Virtually all infection is through the eyes, nose, or mouth. Thus, touching an infected surface then rubbing the eyes or nose is an excellent method contracting them, as is being sneezed or coughed upon by an infected individual.
The "Common Cold" with symptoms in the upper respiratory tract like sneezing, scratchy throat, and runny nose is usually caused by the rhinovirus (up to 40% of colds), or Coronaviruses (about 20%), but there are more than 200 viruses that can cause the common cold.
The seasonal flu, also called "regular flu", is caused mostly by Type A and Type B Influenza viruses.
Although the "stomach flu" is a common term, it is not a real diagnosis. The proper medical term for stomach flu is gastroenteritis (an intestinal disease, sometimes viral but also bacterial), it is often mistaken for influenza because true influenza can sometimes include vomiting and diarrhea.
Viruses.
There is not an individual condition called a muscle cold. What people call a muscle cold is actually the muscle soreness and fatigue associated with a flu. A flu is caused by a virus.
common cold flu salmonella
Flu is very common in Finland, especially during the flu seasons.
same as flu and colds
A cold and the flu are caused by a viral infection.
They exist because particular flu causing germs called bacteria and viruses exist. Colds and flu are extremely common because it is contagious meaning the germs spread easily from contact with the infected person.
man flu
Yes. Because she's a human.
TB FLU COLDS MEASLES etc
sneeze sneeze and cough cough
No. Penicillin is an antibiotic and does not help fight viral infections like colds or the flu. Tamiflu (an antiviral medication) may be prescribed if the flu is caught early enough.
