From 2019, our whole world is facing a survival challenge against an infectious disease caused by newly discovered CORONA Virus or COVID-19. It become a threat to everyone & very soon it turned into pandemic situation. Corona virus is a big family of different viruses. On 31 December 2019, WHO was informed of cases of pneumonia of unknown cause in Wuhan City, China. A novel coronavirus was identified as the cause by Chinese authorities on 7 January 2020 and was temporarily named “2019-nCoV”.
Where did the Coronavirus come from?
Experts say SARS-CoV-2 originated in bats. That’s also how the coronaviruses behind Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) got started. SARS-CoV-2 made the jump to humans at one of Wuhan’s open-air “wet markets.” They’re where customers buy fresh meat and fish, including animals that are killed on the spot.Some wet markets sell wild or banned species like cobras, wild boars, and raccoon dogs. Crowded conditions can let viruses from different animal’s swap genes. Sometimes the virus changes so much it can start to infect and spread among people. Still, the Wuhan market didn’t sell bats at the time of the outbreak. That’s why early suspicion also fell on pangolins, also called scaly anteaters, which are sold illegally in some markets in China. Some coronaviruses that infect pangolins are similar to SARS-CoV-2. As SARS-CoV-2 spread both inside and outside China, it infected people who have had no direct contact with animals. That meant the virus is transmitted from one human to another. It’s now spreading in the U.S. and around the globe, meaning that people are unwittingly catching and passing on the coronavirus. This growing worldwide transmission is what is now a pandemic.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.

OMG! What Should I do?
Seek immediate medical attention if you have serious symptoms. Always call before visiting your doctor or health facility. People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
To Prevent the spread of Covid-19
Properly fitted masks can help prevent the spread of the virus from the person wearing the mask to others. Masks alone do not protect against COVID-19, and should be combined with physical distancing and hand hygiene. Follow the advice provided by your local health authority.
Each & every country are busy to save their people against the CORONA virus. For this pandemic, the tourism sectors in the world had been almost destroyed. The economic condition continuously worst. But finally at the end of 2020, many countries discovered vaccines for protecting against COVID-19. After a decay with lockdown, quarantine- many countries finally announced to open their tourism sector to boost their economic conditions but one step is mandatory for all i.e., all travelers must be fully vaccinated. There are many controversies about which vaccine is approved by foreign countries or not for Indians. In India, 2 vaccines are available- COVISHIELD made by Serum Institute of India & COVAXIN made by Bharat Biotech in partnership with National Institute of Virology and the Indian Council of Medical Research, Covaxin was approved for emergency use on January 3.
Finally, the following EU countries approved the COVISHIELD for the Indian workers, students, tourists also
Dubai, America, UK, Canada, Russia, Turkey also accepts the dual doses of COVISHIELD. They have only condition that before arrival you must have received 2 complete doses of COVISHIELD with certificate. The last dose must be taken at least 14 days before arrival. For safety measure, you must provide the negative PCR test report against COVID-19 which is valid for 72 hours of 48 hours.
Vaccination certificate must include-
Even after control is achieved, given our global connectivity, countries must be prepared for second and subsequent waves of disease brought on by relaxation of travel advisories and exacerbated by seasonal climatic factors. Chronic, endemic surges in SARS-CoV-2 transmission may continue to occur, considering that it is already present globally in human populations, indicating the need for fundamental changes in the way healthcare is delivered around the world.
SARS-CoV-2 is not another ‘common cold coronavirus’ or ‘influenza’. It is clearly able to devastate health systems and economies, in addition to the severe clinical disease it may cause in the medically vulnerable. Decisive public health measures and social responsibility are paramount even as we await scientific advancements such as effective vaccines and antivirals for COVID-19.
