As a medical professional, I have a deep understanding of the nature of diseases and their transmission. When discussing the contagiousness of viral infections, it's crucial to recognize that viruses are microscopic infectious agents that can only replicate inside the living cells of an organism. They are responsible for a wide range of illnesses, from the common cold to more severe conditions like influenza and COVID-19.
Viral infections are indeed contagious. Contagiousness refers to the ability of a disease to spread from one person to another. This transmission can occur through various means, including direct contact, respiratory droplets, airborne particles, contaminated surfaces, and bodily fluids. The level of contagiousness can vary significantly among different viruses. For instance, some viruses like measles are highly contagious, while others may be less so.
One of the key characteristics that distinguish viral infections from bacterial infections is their mode of transmission and replication. While both can cause illness, viruses are generally considered to be more contagious due to their ability to rapidly mutate and adapt to new hosts. This adaptability allows them to evade the immune system and spread more efficiently within a population.
The reference to "colds, flu, croup, laryngitis, chest colds (bronchitis), and most sore throats" being viral in nature is accurate. These conditions are often spread through respiratory droplets produced when an infected person coughs, sneezes, or talks. The proximity to an infected individual and the environment play significant roles in the likelihood of contracting these illnesses. For example, closed spaces with poor ventilation can facilitate the spread of respiratory viruses.
The statement that "viral infections are more contagious than bacterial infections" is a generalization that holds true in many cases but should be taken with some caution. While it's true that some viral infections spread more easily than bacterial ones, there are exceptions. The contagiousness of an infection depends on various factors, including the virulence of the pathogen, the mode of transmission, and the susceptibility of the host population.
The observation that "if more than one person in the family has the same illness, odds are it is a viral infection" is insightful but not a definitive rule. While it's common for viral infections to affect multiple members of a household due to close contact and shared environments, it's also possible for bacterial infections to spread in similar settings, especially if there's a common source of infection.
In summary, viral infections are indeed contagious and can spread through multiple routes. Their contagiousness can be influenced by the specific virus, environmental factors, and the behaviors of the infected individuals. It's essential to practice good hygiene, such as frequent handwashing and covering one's mouth when coughing or sneezing, to reduce the risk of transmission.

Both colds and the flu are contagious and are caused by viruses. ... For colds, most individuals become contagious about a day before cold symptoms develop and remain contagious for about five to seven days. Some children may pass the flu viruses for longer than seven days (occasionally for two weeks).
