Coronaviruses(CoVs) are a family of virus that are zoonotic, meaning they are transmitted between animals and people. Also known as COVID-19, it is said to have originated from Wuhan China, at a sea food and meats stalls which sells wild animal meat. The first cases were reported on New year’s eve. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
The symptoms do not show immediately because in some cases some people picked it up from China and when they arrived in Thailand that is when the symptoms started showing. The coronavirus appears to affect people from 40 years and above mostly. A few cases of children from 13 years to 14 years have been affected but it does not appear to affect small children.
It is speculated that the virus came from eating bat meat or from an animal that had the coronavirus. Its also transmitted from person to person because the virus is airborne.
There is no known treatment yet. Because of this the World Health Organization (WHO) has declared this a global health emergency in 2020. The other times WHO declared a global health emergency is as follows;
Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza is commonly called the flu, but it’s not the same as stomach “flu” viruses that cause diarrhea and vomiting.
2014 – Poliomyelitis
Poliomyelitis (polio) is a highly infectious viral disease, which mainly affects young children. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and can cause paralysis.
Initial symptoms of polio include fever, fatigue, headache, vomiting, stiffness in the neck, and pain in the limbs. In a small proportion of cases, the disease causes paralysis, which is often permanent. There is no cure for polio, it can only be prevented by immunization.
2014 and 2019 – Ebola
Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates. The viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.
2016 – Zika
Zika is spread mostly by the bite of an infected Aedes
species mosquito (Ae. aegypti
and Ae. albopictus
). These mosquitoes bite during the day and night. Zika can be passed from a pregnant woman
to her fetus. Infection during pregnancy can cause certain birth defects. There is no vaccine or medicine for Zika.
SARS a short term for Severe Acute Syndrome is a contagious and sometimes fatal respiratory illness caused by a coronavirus.
Treatable by a medical professional
Requires a medical diagnosis
Lab tests or imaging always required
Short-term: resolves within days to weeks
Critical: needs emergency care
SARS appeared in 2002 in China. It spread worldwide within a few months, although it was quickly contained. SARS is a virus transmitted through droplets that enter the air when someone with the disease coughs, sneezes or talks. No known transmission has occurred since 2004.
On the other hand MERS meaning Middle East Respiratory Syndrome is caused by a coronavirus. MERS-CoV has spread from ill people to others through close contact, such as caring for or living with an infected person.
MERS can affect anyone. MERS patients have ranged in age from younger than 1 to 99 years old.
The Coronavirus has affected Hubei the most thus the place is quarantined. Wuhan on the other hand has experienced both a city wide evacuation since January 23 2020 and quarantine. Most people use masks on a day to day basis. All the borders have been closed and flights suspended in order to contain the virus. So far the death toll is at 810 people and about 2000 people are affected. Research suggests that if one’s immune system has problems or one has an underlying health problem there is a more likely chance of dying.
Due to the rising number of cases of people affected by the coronavirus the doctors have been on there toes ever since. In one extreme case a doctor loses consciousness due to exhaustion from work, click here
to watch that, even after suffering a head injury and losing his front teeth from the fall, he insisted on going back to work. All these diseases have one thing in common and that is they are viruses and researchers continually try to find a cure but mostly come up with a vaccine to prevent them while some viruses do not have a remedy and thus containing it is the best chance.
