What is coronavirus?
Coronavirus (Covid-19) is a type of virus that causes symptoms similar to the common cold ranging all the way to more serious respiratory symptoms. The new virus that has emerged in 2019 is currently known as the novel coronavirus.
The novel coronavirus is a completely new strain of coronavirus and it can be transmitted from person to person. At the moment, there is no solid lead on where this originated from and experts are working hard to find the source. While some experts believe it originated from a wild life market in Wuhan, it will still be some time before this can be confirmed. However, once the source is found, it will be easier for doctors to create a vaccine.
Where did the coronavirus come from?
The virus was first confirmed from the city of Wuhan in China. The actual source and patient zero hasn’t been confirmed but there is wide speculation from medical experts that the virus originated from the wet market which kept live animals. The latest information suggests that the first confirmed case could be from november 2019.
Symptoms of the CoVn include;
It's important to note that the majority of those who have died from the illness are elderly and or have pre existing illnesses. Therefore its essential for everyone to minimise their exposure to the infection and to prevent it by following these rules;

How is it spread?
Much of the information on how to prevent the transmission of novel coronavirus is based on existing information on typical coronavirus transmission, which typically is spread when a droplet of moisture from an infected person enters an uninfected via eye, nose, mouth or open wounds.
Normally, coronavirus are most contagious when symptoms are showing, but there are some reports that there are human to human transmission even when there are no symptoms. Any who has been in close contact with a potentially infected person which is defined at being within 6.5 feet (2 meters) of them for 15 minutes.
If you have traveled to China and start feeling sick with cough, fever and or difficulty breathing you should immediately seek medical care. However, before you make your way to the doctors or the emergency room at the hospital, please call ahead and inform them about your symptoms, your travel history and if you have potentially been in contact with someone suspected to have the virus.
What has been done to deal with it?
One of the first things officials in China have done is seal off the city of Wuhan where the virus originated from in an attempt to stop the infection. All major transportation going in or out the city has been stopped and roadblocks put into place. To further attempt to stem the contagion, many countries have banned any foreign nationals from arriving if they have been traveling in China in the last 14 days.
Many countries have also begun evacuation of their nationals and under very strict monitoring and will be quarantined for 14 days as this is the incubation period of the virus.
In addition to those measures, authorities are arming their staff with temperature guns to check passengers and traveling passing through borders. Anyone reported with a fever will either be denied entry or taken straight to the hospital.
What safety gear do you need?
Medical and border staff are armed with protective gloves and surgical masks with the most common standard being N-95. This means the mask, or also known as Surgical N95 Respirators, will filter out 95% of all airborne particles that are at least 0.3 microns, but it will not filter oil*. This is not necessary for ordinary healthy citizens, instead keeping up a clean regime where you wash hands and disinfect your shared work and home space is advised.
If you are still worried, medical experts have warned that regular face masks will not help much but can be used if there is nothing else. For a comprehensive list of companies that sell approved N95 masks please click here.
It should be noted that due to the increase in cases, there has been a surge in demand for face masks especially for N-95 ones. In such cases please be mindful that medical workers require them more urgently as they face a whole variety of disease and infection on a daily basis.
What can you do to check if other people have the virus?
One of the first signs for the coronarivus (covid-19) is a sore throat, cough and a fever. It would be difficult and nearly impossible to determine if a passerby has a sore throat and a cough that isn't a regular cough. This is where the fever comes in and why so many medical staff and border controls conduct a temperature check. Fevers, especially high ones, are an indication that the body is fighting off a serious problem. A common illness like the cold and cough, would not produce a high fever in a healthy individual so medical staff monitor people with fevers.
Laser Temperature Guns or Thermal Camera?
Normally a contact thermometer is used on suspected patients with a fever, you would typically put this in the mouth, under the arm and so on, however, due to the high infection rate of the coronavirus, it's extremely dangerous for personnel to be in such close contact. The solution? Temperature thermometer guns or thermal cameras.
Temperature thermometer guns are a gun-shaped meter that can measure the surface temperature at a spot location which can range from 2 cm - 12 cm depending on the distance. These work very well if they are calibrated correctly as many of these temperature thermometer guns can range from 0 up to 1922F. Therefore to increase the accuracy, special laser thermometer guns are calibrated to a much smaller range but with much higher accuracy.

Thermal cameras, on the other hand, could provide a more accurate image and do mass checks at once. They work by measuring the heat signatures of various objects and in this case humans, and they display the findings into a normal visible-light image. They don’t have the limitation of focusing on one particular point to find the temperature which makes it a great choice to screen mass passengers at once. However, in some cases, they lack the level of accuracy needed to check for fevers and thus one scenario could be that any slight deviation from normal temperatures could be further checked with a laser thermometer gun.
