Let us understand what a coronavirus really is and how it comes about, its origin and nomenclature, before delving deeper into precautions, preventive measures, natural modes of relief and home care. Coronaviruses are zoonotic. What does that mean? Well, what comes to mind when you hear the word “zoo”? That’s right, animals! Zoonotic illnesses are hard to get rid of as they have an animal reservoir, like bird flu, while it can be abolished in farmed animals but keeps coming back as it is brought by wild birds. You don’t hear much about avian influenza as it doesn’t transmit from person to person, but there are outbreaks in poultry farms every year worldwide. So zoonosis refers to an infectious or contagious disease that is transmitted from a non-human source, such as insects, birds, other mammals and animals. Coronaviruses (CoVs) are subsets of viruses with unique characteristics, like they use RNA instead of DNA, and belong to the family Coronaviridae comprising a group of enveloped, positive-sensed, single-stranded RNA viruses. Covered with spikes to invade cells, those spikes or crown-like S proteins are called corona, Latin for wreath or crown. There are more than 30 kinds, but usually only a few affect people which are called human coronaviruses (HCoVs). All human coronaviruses are zoonotic i.e. transmitted between animals and people, usually originating from bats, mice or domestic animals. These coronaviruses often cause what we know as the common cold or flu, and symptoms may include fever, cough, headaches, sore throat, running nose, fatigue, sometimes reaching the severity of pneumonia. So far, there have been seven types of Coronaviruses affecting humans, the seventh being the one discovered in December 2019 creating this worldwide pandemic COVID-19, a respiratory illness colloquially known as the coronavirus. Some coronaviruses like this one causing COVID-19 also spreads person to person, hence travel faster and farther. Indirect contact via contaminated surfaces is another possible cause of infection.
