A coronavirus is a type of virus that infects many animals, from peacocks to pangolins. While there are many kinds of coronaviruses, only seven of them can cause disease in humans. A coronavirus infection affects humans in two ways: a lung infection (common cold) or a gut infection resulting in diarrhea.
The most recent kind of coronavirus, for example, is called SARS-CoV-2. It is responsible for a global outbreak of dangerous—and sometimes fatal—respiratory illnesses, now known as COVID-19.
4 out of 7 of the kinds of coronaviruses that affect humans are largely non-deadly. At most, they cause seasonal flus, or the common cold. However, any of these kinds of coronaviruses may cause serious respiratory illnesses when combined with underlying health or immune issues.
All seven kinds of coronaviruses cause infections in the upper respiratory tract. Symptoms include:
However, coronaviruses have been known on occasion to cause lower respiratory tract infections such as pneumonia. These complications largely affect infants, as well as adults that are immunocompromised, or have underlying illnesses.
Three kinds of coronaviruses that are originally animal infections pose more dangerous risks to humans. Their more specific symptoms are detailed below:
These symptoms usually manifest after about a week of incubation. However, the SARS-CoV has been contained, with no known cases as of 2020.
These symptoms begin to appear 5-6 days after exposure.
Symptoms typically appear around 5-14 days after exposure.
Warning signs for coronavirus infections include:
The various kinds of coronaviruses are classified due to their spiky appearance. These spikes contain proteins that latch onto human cells. It then transforms, and proceeds to infiltrate the human cell with the virus’ own genetic material.
The new SARS-CoV-2 virus prefers to grow in type II lung cells, which are responsible for helping air enter the lungs. The immune system panics and proceeds to indiscriminately invade and destroy lung tissue in an attempt to eliminate the virus.
The SARS-CoV-2 virus seems to predominantly affect the older population. This is because older patients tend to have underlying issues or chronic health illnesses. These conditions run the gamut of cardiovascular, kidney, lung diseases and diabetes, to immune compromisations, and cancer.
The main mode of transmission for various kinds of coronavirus is through droplets from the nose or mouth. Coronaviruses may continue to live on surfaces that humans touch, then proceed to transfer to their eyes, noses, or mouths.
The Sars-CoV-2 is especially dangerous because it is spread quickly and easily compared to other kinds of coronaviruses.
Respiratory secretions are tested to determine the specific virus causing symptoms. However, testing positive for the other kinds of coronavirus does not equate to being positive with COVID-19.
There is no known cure for the many kinds of coronaviruses. Treatments for coronavirus infections involve supportive care, managing symptoms, as well as containment and mitigation.
Concerned about your symptoms? Contact your doctor or primary healthcare provider.
While there is currently no vaccine to protect against the many kinds of coronaviruses, here are some ways to relieve symptoms:
The best cure, however, seems to be prevention. Here are some ways to prevent becoming infected with coronaviruses:
When sick, prevent the spread of infection by doing the following:
As with a majority of illnesses, prevention is the best kind of cure. The global pandemic spread by the SARS-CoV-2 has currently shaken the modern world.
Practicing social distancing, self-quarantining, and fastidious personal hygiene practices may be what protects your family and community from infection. Consult with your doctor, local government units, and reputable health sources to stay updated, informed, and safe.
