Contagious and infectious diseases are both caused by bacteria or virus strains, but there are some distinctions that differentiate one from the other; particularly in the way they are transmitted and treated.
What are Contagious Diseases and How are They Transmitted?
The most common types of contagious diseases are colds, strep throat or flu, which like infectious diseases can be transmitted by one person to another but in a number of ways. Aside from direct physical contact, a disease-causing bacteria that is airborne can still infect people when a person spreads microbes in the air through coughs or sneezes, or by contaminating objects by simply holding and touching something that someone later touches.
In public places, an afflicted person can transfer disease-causing microbes by simply touching door knobs, door handles, faucets, rails, public phones, countertops and similar objects that other people tend to touch or hold. At home, kissing, intimate contacts, sharing of spoons, tumblers, straws, sleeping in the same room, or even stepping on the same floors already carrying disease-causing microbes can result in the spread of a contagious disease among other family members.
The bottom-line difference between contagious and infectious diseases is that the former can be easily transmitted even without direct contact with persons infected by a virus or bacterial strain.
What are Infectious Diseases and How are They Commonly Transmitted?
Infectious diseases on the other hand can affect an individual when a specific strain of virus invades the body and cause health problems. Often times, people acquire an infectious disease when bitten by an insect, or in some cases, ingest contaminated food or liquid.
However, an infectious disease does not necessarily result in a contagious health problem. This denotes that an infection can be contained within the body of the infected person, for as long as the viral strain does not transfer to the bloodstream of another person by way of body fluids.
Body fluids that can cause an infectious disease to spread include saliva, blood, breast milk, semen, pre-seminal discharge and other excretions produced by a person through his or her excretory and/or reproductive organs (e.g.rectum, vagina and penis).
Transmission of body fluid can be carried out by way of direct contacts such as kissing, and all types of carnal or sexual activities. Rare cases, are when infection is transmitted by using hypodermic needles usually for injecting drug.
The most serious types of infectious diseases are those categorized as sexually transmitted diseases, which at worst, can lead to HIV and AIDS.
Avoiding Both Contagious and Infectious Diseases
The best way to avoid infectious diseases caused by humans is by not engaging in promiscuous sexual relationships and activities. Keeping your surroundings free from breeding grounds of insects capable of transmitting infectious diseases, as well as eating only food grown, manufactured, processed, and/or cooked under sanitary conditions are also ways of avoiding infectious viral strains.
Contagious diseases are often avoidable by keeping your hands clean through frequent washing before taking in food. Homeowners, and administrators of public places must also maintain surroundings clean, in order to avoid the spread of contagious diseases.
Homes with Ring Doorbells may find the audio video features of the doorbell system advantageous when it comes to keeping their home under quarantine conditions. If a homeowner needs to quarantine himself or a member of the family within the confines of the home, they can still communicate with people arriving at their doorstep via the built-in communication system of a Ring Doorbell.
Ring Doorbells though come in different models that have distinguishing features. Take for example the Ring 2 and the Ring Pro, which although having similar capabilities have some specific differences. Read about their differences by looking up Ring 2 vs Ring Pro comparison articles so you can make the best buying decision on which model suits your home and your lifestyle.
