With the increase in coronavirus cases, many countries have closed their borders. Scientists from all countries of the world are working to find the origin and the treatment for coronavirus while some leading pharma companies are working on its vaccine development. As there is less scientific data available on this novel virus, some of the biggest coronavirus controversies utilized this time to mislead people; thus adding up to its spread.
This virus first appeared in December 2019 in Wuhan, China, and eventually spread to the whole world within a few weeks. At the start, it was considered as common flu but when it started taking lives, the health departments were alerted of something more dangerous than ordinary flu.
This is the first time that coronavirus is here among humans. Before this, it was only observed in animals. There is almost zero information available on its origin and every information that is in front of people is merely based on assumptions and opinions of researchers.
Despite conducting so many studies to know the whereabouts of this virus, there is still no significant progress. But it doesn’t mean that science has failed and there is no hope. It will take time but till that time comes, people need to educate themselves especially related to the ‘biggest coronavirus controversies’ to play an active part in pandemic control.
Controversy#1 Using face masks
COVID-19 is an airborne infection that primarily spreads through sneezing, coughing, and talking to people sprinkling droplets on their faces. That’s why wearing a mask has made compulsory in major parts of the world.
But it doesn’t mean that face mask is a treatment from coronavirus; it only prevents the droplets to spread or transmit to other people. Otherwise, this mask doesn’t do anything else.
Scientists have mixed opinions on the efficacy of face masks. The Royal Society fully favors using face masks when practical social distancing may not be possible. Another study on coronavirus infected children showed that wearing a mask helped them from transmitting the virus to other family members. But face mask may not help against all airborne particles. Another study calls a face mask to give a falsified sense of security, and people may choose to ignore other measures when they are wearing masks.
Controversy# 2 Immunity against COVID-19
Researchers are trying to find out if people can get ‘immune’ to the COVID-19 or not. Many of these studies talk about some neutralized antibodies that are produced by the B-cells of the body. These B-cells attach to the proteins in viral structures and could prevent the infection to begin. These antibodies will be present for a few weeks once the disease ends. A Chinese study confirms a significant decline in coronavirus positive people within 2-3 months of recovering. It is a confusing situation that doesn’t tell if there would ever be a long term coronavirus protection available or not. Even if a person acquires immunity, there are chances that it would be short term.
Controversy#3 Coronavirus cases
There is a general assumption that coronavirus cases are falsely recorded. Some areas report less than 1% of the infection rate on the other side, more than half of the total population is infected in another country. It is assumed that these reported cases are only the symptomatic cases and the official records omit asymptomatic cases and those which recovered naturally.
In this situation, it is hard to predict the actual coronavirus cases in the world. The results are based on the antibody testing or predictions made with mathematical models.
