During global health emergencies, some words become part of our vocabulary. Two of them are the isolation and quarantine, a duo of words heard, read, and repeated in various forums, particularly during the COVID-19 pandemic.

Knowing these words isn’t merely about definitions; it’s about understanding how and why they are used in public health interventions.

What is Isolation

In lexicon it has been described as the act of separating oneself or being separated.

What is Quarantine

A period of separating or isolating oneself after being exposed to infectious or contagious diseases.

More Than Just Distance: Isolation vs Quarantine Explained

It’s easy to define both, and as noticed, it is the definition on which protocols are being based on the COVID pandemic. It must be noticed that there is a very thin line of demarcation between Isolation and quarantine. All patients of quarantine are actually in a form of isolation but all isolation patients are not quarantined.

It’s basis is on the appearance of disease symptoms or how healthy you appear. Yes! we shouldn’t get hyped that we or the other persons are looking healthy. It should be clearly stated that a person is apparently healthy until proven otherwise. This distinction is critical when designing public health protocols, especially during pandemics.

Associated Terms

Infectious & Contagious Diseases

Herein these terms must be understood clearly which automatically superfies the importance of isolation and quarantine. Firstly, all contagious diseases are communicable diseases as they need a source, vector to transmit. Thus, all contagious/ communicable diseases are infectious and need contact.

In contrast, all infectious diseases are not communicable they may be non-communicable too but they are infectious still as there is role play of some infectious agents. Some examples of contagious diseases are Covid 19,  Ebola, Hantavirus etc….

2-Airborne & Droplet Transmission


Another term which needs to be comprehended are terms air-borne and droplet; as it determines the type of isolation required. It also determines to what extent the protective gear is needed when healthcare workers and associated paramedics come in contact.

Air-borne: In air-borne, germs on coughing, sneezing etc as term states will stay in air for some time and will affect and enter through eyes, mouth and nose etc. like chicken pox, tuberculosis etc.

Droplet: It is when germs because of cough, sneezing travel inside the droplets and through these droplets can enter mouth, nose etc. It this occurs over short distances of usually less than 3 feet (1 metre). Another mode is when you touch surfaces where the germs are and then touch eye, mouth etc. Examples are: Ebola, plague etc.

Isolation Types:

Isolation is of the following types:

Contact isolation: It is used to prevent diseases through contact with open wounds.

Respiratory isolation: This term is not so common among laymen and is used where chances of transmission are exponentially increased thru exhalation. It requires special precautions by health care workers.

Reverse isolation: This term is used when you do not want patients in compromised states to be exposed to harmful substances in the environment. In this case, you will wear a certain gear not to protect yourself but to protect patient from you. One example is post-transplantation when immune system is knocked down to avoid rejection.

Self isolation: This time being frequented nowadays is a form of quarantine. If it is self-quarantine its like social distancing meaning:

  • Avoiding large gatherings
  • Keeping a distance of at least 6 feet from others
  • prefering online learning/ home working etc

Other self-isolation is like home isolation and a form of quarantine after risk of exposure or an identified contact but without symptoms. Isolation may be modified if symptoms appear etc.

In these unpredictable days, there is more need of being compassionate with empathy and indeed someone has said rightly that “Prevention is better than cure” and it goes a long way.

When Separation Saves Lives: The Human Side of Isolation and Quarantine

We hear the words isolation and quarantine, but we don’t usually consider what they entail on a human basis. Isolation is not simply keeping a person in a hospital room, it may be away from family, rituals, and even emotional support.

For most individuals, lying alone in bed when they are sick is not only a medical procedure, it’s also a psychological battle. They fight symptoms in isolation, not wanting to share them, and with fear, loneliness, and uncertainty.

Quarantine can be just as challenging. Consider being well but being separated from your life, just because you may pose a risk to others. It’s a silent, invisible sacrifice. You can’t go to work, hug your loved ones, or even pick up groceries. And yet, people do it. They remain home, obey, and ride out the uncertainty, not because it’s simple, but because it’s necessary. Their decision to be careful safeguards countless others who might be more susceptible.

Behind each word, each graph, each guideline, there is an individual making a decision — to isolate, to quarantine, to care. These acts may be tiny, but they are acts of empathy. They are saying, “I care for your life as much as for mine.” In an era where distance equals responsibility, these actions are not merely public health interventions, they are acts of humanity. Because sometimes, the best way to remain connected is to remain separate.
