Coronavirus (Covid-19)
Coronaviruses or we can call this virus Covid-19 these viruses are a large family of viruses that
cause illness ranging from the common cold to more severe diseases. Coronavirus disease is a
new strain that was discovered in 2019 and has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people.
Common signs of infection include lung symptoms, fever, and cough, shortness of breath and
breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute lung
syndrome, kidney failure and even death.
In 1937, coronaviruses were first identified as an infectious bronchitis virus with which birds
suffered that could devastate poultry stocks. Today, the viruses are the cause of the common cold
in 15% to 30% of all cases. In the past 70 years, researchers have found camels, cattle, cats,
dogs, horses, mice, pigs, rats and turkeys that were infected with coronaviruses.
After that on December 31, 2019, the World Health Organization’s (WHO) China office heard
the first reports of a previously-unknown virus behind a number of pneumonia cases in Wuhan, a
city in Eastern China with a population of over 11 million. The disease appears to have
originated from a Wuhan seafood market where wild animals, including marmots, birds, rabbits,
bats and snakes, are traded illegally. Coronaviruses are known to jump from animals to humans,
so it’s thought that the first people infected with the disease – a group primarily made up of
stallholders from the seafood market – contracted it from contact with animals. The Wuhan
market was shut down for inspection and cleaning on January 1, but by then it appears that
Covid-19 was already starting to spread beyond the market itself.
The 2019 novel coronavirus has the potential to be a global pandemic. Health officials say it
originated in a market in Wuhan, China that sold live and dead wild animals that people ate for
food, improved health and vitality and a number of other purposes. The virus has now been
detected in Australia, Canada, Finland, France, India, Italy, Japan, Nepal, Russia, Singapore,
Spain, Taiwan, Thailand, Vietnam, Bangladesh and the United States and over a dozen other
countries.
The virus was confirmed to have spread to Bangladesh in March 2020. The first three known
cases were reported on 8 March 2020 by the country's epidemiology institute, IEDCR. Since
then panic spreads day by day over the whole nation and the number of affected people is
increasing. In order to save all the people, the government declared "lockdown" throughout the
nation from 23 March to 30 May and prepared some necessary steps to spread awareness to keep
this syndrome away from them. Infections remained low until the end of March but saw a steep
rise in April.[3] In the week ending on 11 April, new cases in Bangladesh grew by 1,155 percent,
the highest in Asia, ahead of Indonesia, with 186 percent. On 13 June, the number of cases in
Bangladesh exceeded the number of cases in China, the country where the outbreak began. As of
3 July 2020, there have been a total of 156,391 confirmed cases in the country, with 68,048
recoveries and 1,968 deaths.
In worldwide 3 July 2020, there have been 10,719,946 confirmed cases of COVID-19, including
517,337 deaths, reported to WHO.
Currently there’s no cure for the 2019-nCOV virus. Common treatments that have proven to be
somewhat effective in controlling the symptoms include taking over-the-counter medication,
drinking lots of water, getting adequate rest, avoiding overexertion, not smoking, staying away
from smoky areas and using clean mist vaporizers or humidifiers.
Taking medications like acetaminophen, ibuprofen and naproxen can help to reduce the pain and
fever associated with the illness.
