2. The cold virus is not just one virus

3. Children can have up to 12 colds in a year

4. A quarter of people with colds do not experience symptoms
We all know the symptoms of colds. After all, it’s one of the most common diseases.
However, not everyone knows that some people can be infected with one of the cold viruses and not have a cough, sneeze, or runny nose.
5. A sneeze can travel as fast as 60 km per hour (37 mph)!
The reality is that measuring the speed of a sneeze isn’t easy, but this is what specialists calculated. For a bit of perspective, greyhounds can run 60 km/h!
In some cases, a sneeze can even exceed this speed and the saliva drops can fall up to five meters away!
6. Viruses from common diseases can survive on various surfaces.
When you sneeze, you spread the virus around you and it can stay active on different surfaces. For example, the flu virus can survive about 24 hours, and the cold virus, up to seven days!
Now, do you understand why it’s so important to cover your mouth with your elbow when you sneeze? That way, you avoid infecting others.
7. The flu is constantly evolving
The flu is one of the common diseases that people contract the most throughout their lives. Surely you know that there are three classes of Influenza: A (this is the most virulent and affects humans and birds), B (this is the most common and affects only humans), and C (this is less common and affects humans and animals).
However, every year new strains of each type of Influenza appear. For this reason, vaccines can’t always protect you, and you may still end up getting sick.
8. In the last century, we’ve had several influenza epidemics
Today, the flu is a common disease that people don’t usually pay attention to. However, as we’ve already seen, it’s extremely easy to transmit through saliva and can also cause complications such as pneumonia.
- The Spanish flu lasted from 1918 to 1919 and affected 40% of the world’s population. In fact, it claimed the lives of approximately 50 million people around the world. One interesting fact: Despite its name, it did not originate in Spain, but in the United States.
- The Asian flu originated in China in 1957 due to the mutation of a virus transmitted by wild ducks in combination with a human strain.
- The Hong Kong flu left approximately one million dead. Thanks to technological advances, they developed a vaccine that prevented further loss of human life.
- The swine flu of 1976 caused more than 12,000 victims and caused panic among the population since the virus was similar to that of the great epidemic of 1918.
- Bird flu had its first outbreak in Hong Kong in 1997. The virus was identified as H5N1 and after being controlled, it reappeared in 2003 in Asia and Europe.
