What is Covid-19

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).[6] The disease was first identified in 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic.[7][8] Common symptoms include fever, cough, and shortness of breath.[9] Other symptoms may include muscle pain, sputum production, diarrhea, sore throat, loss of smell, and abdominal pain.[4][10][11] While the majority of cases result in mild symptoms, some progress to pneumonia and multi-organ failure.[7][12] As of March 28, 2020, the overall rate of deaths per number of diagnosed cases is 4.6 percent; ranging from 0.2 percent to 15 percent according to age group and other health problems.[13]
The virus is mainly spread during close contact and via respiratory droplets produced when people cough or sneeze.[14][15] Respiratory droplets may be produced during breathing but the virus is not generally airborne.[14][16] People may also contract COVID-19 by touching a contaminated surface and then their face.[14][15] It is most contagious when people are symptomatic, although spread may be possible before symptoms appear.[15] The virus can survive on surfaces up to 72 hours.[17] Time from exposure to onset of symptoms is generally between two and fourteen days, with an average of five days.[9][18] The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab.[19] The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia.[20][21]
Recommended measures to prevent infection include frequent hand washing, social distancing (maintaining physical distance from others, especially from those with symptoms), covering coughs and sneezes with a tissue or inner elbow, and keeping unwashed hands away from the face.[22][23] The use of masks is recommended by some national health authorities for those who suspect they have the virus and their caregivers, but not for the general public, although simple cloth masks may be used by those who desire them.[24][25] There is no vaccine or specific antiviral treatment for COVID-19. Management involves treatment of symptoms, supportive care, isolation, and experimental measures.[26]
The World Health Organization (WHO) declared the 2019–20 coronavirus outbreak a Public Health Emergency of International Concern (PHEIC) on 30 January 2020[27][28] and a pandemic on 11 March 2020.[8] Local transmission of the disease has been recorded in many countries across all six WHO regions.[29]

Migrant Workers Sprayed With Disinfectant In One Indian State

Migrant Workers Sprayed With Disinfectant In One Indian State New Delhi (CNN) The Indian state of Uttar Pradesh has sparked controversy after migrant workers, returning home during a nationwide coronavirus lockdown, were doused in bleach disinfectant used to sanitize buses. Video showed three people, dressed in protective gear, spraying the liquid directly on a group of Indian workers as they sat on the ground in the northern city of Bareilly. Social distancing is a privilege of the middle class. For India's slum dwellers, it will be impossible Ashok Gautam, a senior officer in charge of Covid-19 operations in Uttar Pradesh, told CNN as many as 5,000 people have been "publicly sprayed" when they arrived before they were allowed to disperse. "We sprayed them here as part of the disinfection drive, we don't want them to be carriers for the virus and it could be hanging on their clothes, now all borders have been sealed so this won't h...

Why COVID-19 makes a compelling case for the wider integration of blockchain

Why COVID-19 Makes A Compelling Case For The Wider İntegration Of Blockchain The COVID-19 crisis has revealed a general lack of connectivity and data exchange built into our global supply chains. Future resiliency will depend on building transparent, inter-operable and connective networks. When it became clear that many of us would soon be working from home, a majority took a cursory glance at their home office set-ups and decided it needed upgrading. What ensued was an unanticipated rush and surge of online orders for office desks, chairs, lamps and computer hardware. But such was the sudden spike that it has unsurprisingly caught suppliers large and small unprepared, off guard and exposed gaping holes in their ability to track purchases from one end of their supply chains to the other. Some customers, who have spent no small amount on revamping their home offices are still waiting to do so, without the consolation of being able to see where their orders are, or when they...

What the COVID-19 pandemic tells us about gender equality

What the COVID-19 Pandemic Tells us About Gender Equality Women make up 70% of all health and social-services staff globally. Domestic, sexual and gender-based violence increases during crises. Women earn just 79 cents for every dollar men make. Given that the COVID-19 crisis affects men and women in different ways, measures to resolve it must take gender into account. For women and girls, vulnerabilities in the home, on the front lines of health care, and in the labor market must be addressed. Regardless of where one looks, it is women who bear most of the responsibility for holding societies together, be it at home, in health care, at school, or in caring for the elderly. In many countries, women perform these tasks without pay. Yet even when the work is carried out by professionals, those professions tend to be dominated by women, and they tend to pay less than male-dominated professions. The COVID-19 crisis has thrown these gender-based differences into ...
