And ‘now it clears that COVID-19 is not “just the flu.” Without a vaccine or treatment it is available, the new coronavirus has spread to communities around the world with virtually no control, then whole cities and countries go to block their best defense against the disease in rapid motion. COVID-19 and the flu share some symptoms: cough, fever, weakness, muscle pain. But as March 17 COVID-19 has killed about 4% of the approximately 200,000 people who have been diagnosed with the disease worldwide. Influenza is against it infected millions of people each year, but usually less than 0.1% killing them. COVID-19 requirements are taken seriously, but the mortality rate associated with it, not set in stone, and can also get far less than 4%. Since the outbreak began COVID steam-19 in Wuhan, China to pick up in January, experts were scrambling to get a grip on the disease and how it behaves. But they also warned that the estimates are not accurate, and that the numbers are likely to change over time. An important reason: People with milder versions of the disease in cases of official counts underrepresented because it can not be sick enough to see a doctor, or to realize that something more than a cold. Some people, research suggests can now get infected and become contagious, it is noted without any symptoms. This means that the total number of cases reported is very likely and underestimation, not to mention a lot of asymptomatic or mild cases, there are probably overstate the total disease mortality. The same problem is probably true for other diseases such as influenza, which vary in intensity from year year, but is particularly pronounced in an unprecedented outbreak with limited ability to test. Overlooking data from countries with robust test systems, the idea works support that the lethality of the disease can be 4% less. Countries that have tested the many people generally report lower mortality rate than those who have not tested, and focused on serious cases. This suggests that to be extended in the testing of networks to capture people with less severe disease, and case counts this sector reflects the severity, mortality rates go down. The mortality rate in South Korea, where 5,597 tests had been administered up to March 17 per million inhabitants, is at 0.97%, for example. In Japan, where only 130 tests were administered per million population, the mortality rate is 3.3%. What the United States in recent weeks, this trend shows clearly happened: On March 5, when the country only 58 per million, the mortality rate was approximately 5.4% to a rate of testing was; until March 17, almost triple test rate and the number of deaths dropped 1.7%. The same logic suggests that surprisingly low rates of infection in some of the busiest parts of the globe, a sparse 174 reported cases among the countries of sub-Saharan Africa, 1.1 billion people, as poor monitoring reflects more than hope. Only a few countries are testing at relatively high levels reported mortality rates of over 2%, but Italy has provided an outlier test. date with more than 2,400 tests per million inhabitants, the country still recorded a rate of nearly 8% mortality. While the exact reason for the discrepancy is not clear, it could lead to differences in test strategy of the country, the test shows used specific or unique, something about the real blast there. One prominent theory is that Italy has suffered more than most countries because of its relatively older population. According to the United Nations, Italy has the highest average age and according COVID-19 world seems particularly dangerous to the elderly. see also when taking the estimated current global mortality rate of 4% at par-19 COVID more as the influence of other once crown novel, although it appears to be more contagious than other strains of the crown family. Severe Acute Respiratory Syndrome (SARS) has killed about 10% of people who were, while the Middle East Respiratory Syndrome (MERS) was even more deadly, killing 34% of patients. Of course there is uncertainty in the amount of MERS and SARS, although these figures are based on the post-outbreak epidemiologists calculations. At least so far, COVID-19 seems more deadly than seasonal flu, but is closer to that end of the spectrum, such as the crown for the previous outbreaks. And that global testing has been limited on the basis of fact and that at this point usually only tested with the most severe symptoms or the highest risk of infection, so it makes sense that I introduced when we have a complete picture of how many people with COVID-19 is infected, its mortality may actually drop. The search begins this opportunity to reflect: a new, but not yet peer-reviewed paper in the journal Nature presented Research estimated, on the basis of data available from Wuhan that the total lethality is about 1.4%. The researchers found that could be even lower, because their analysis only accounted for reported symptomatic cases. That said, there is at least one important difference between seasonal flu and COVID-19: we have a vaccine for the former, but not the second. During a 19-COVID investigational vaccine being developed, even if it is proven safe and effective, it is not available to the public for at least a year. Meanwhile, the only way to slow and eventually stop the spread of a pathogen such as a seemingly virulent than 19-COVID aggressive social distancing and be tested on a scale that people with clear guidelines for their personal risks for their available community can provide, and public health officials with population-level information they need to make the right policy decisions. Experts call this “flattened” curve. If a community does not take adequate precautions his local outbreak could not quickly out of control and flooded in a crisis, when the health care system with a number of cases can not be processed in advance. The objective is to avoid a sharp uptick concentrated in the cases that the ability of the healthcare system exceeds favor an outbreak of more than stays within the limits of the handle what the system, they can get sick and die in total fewer people . Some countries are successful. South Korea, for example, quickly adopted a reform of government, local manufacturers could test the basic requirements of that make, test resources within a few weeks after the outbreak in Wuhan intensification of growth. As a result of this decisive action, he was able to intervene rapidly to implement drive-through test centers such as to suspend for extended diagnostics with a minimum risk of allowing it to others. Hong Kong, Singapore and Taiwan also has good results of the travel controls and cases of early aggressive surveillance, while Hong Kong, Singapore and Japan have seen benefits from state funding that the cost covers testing and individual therapy, according to a new document Hand. There is still time to smooth the curve in the United States, but time is running out. Models show the CDC reported that slow without sufficient efforts for the virus may die a million Americans and more than 20 million could end up in the hospital. The country has already taken some steps to combat the worst, but there is still much to do. The US government was quick to restrict international travel, and the Americans encouraged to stay home and avoid large social events, although some critics say that leadership should come first. Demand for COVID-19 testing also outpaces supply still far and hospitals for patient preparation wave certain fear crucial supplies entry to run. These problems require systemic solutions, but people are not powerless. Healthy individuals, or is not able to wash their hands often simply their part and keep your distance from others. the temporary isolation may be what is needed for the country rebound from COVID-19 to help together. image of the copyright of the National Institutes of Health / AFP / Getty Images
