COVID-19, a disease caused by a new coronavirus (SARS-CoV-2), is continuing to spread throughout the world. The World Health Organization (WHO) has officially called a-pandemic disease epidemics that occurred in the broad geographic and affect a very high proportion of the population. The United States has declared the pandemic a national emergency, and states across the country taking major steps to slow the spread of the disease.

According to the WHO, globally there have been nearly 180,000 confirmed cases of people sick and close to 7,500 people have died from the disease-deaths has far surpassed that of the severe acute respiratory syndrome (SARS) epidemic occurred in 2002 and 2003. officials everywhere have implemented measures to contain the virus, including cancellations, closures, travel restrictions and quarantine.

While the immediate risk to COVID-19 is still considered to be low for most Americans, the CDC expects that change as the outbreak expands. US national is considered in the “initiation phase,” according to the CDC, although the countries with the deployment of the community are in “accelerated phase,” and the length of this phase can vary depending on the characteristics of the virus and public health responses.

People in the US face significant disruptions, including unprecedented cancellations, delays and shutdowns of everything from schools to religious services as the community grows transmission report. In the coming months, the CDC estimates that the majority of the US population will be exposed to the virus.

SARS-CoV-2 are viruses that scientists have not seen before. Like other viruses-including Ebola (deadly infectious diseases originating from Africa) and influenza-it was believed to have started in animals and spread to humans. (In particular, SARS-CoV-2 is betacoronavirus, which means it has its origins in the bat.) Business-to-person spread of suspected after the initial outbreak in December among people who have a link to the Great Sea and the market of live animals in Wuhan , China.

Scientists and public health officials are working to find answers to key questions about the severity of the disease and transmission.

Below is a list of five things you should know about the outbreak of coronavirus.

The name refers to the spikes seen (under a microscope) on the surface of the virus (corona is the Latin word for crown). Coronavirus causes respiratory illness ranging from the common cold to deadly diseases such as SARS, also first identified in China, and the Middle East Respiratory Syndrome (mer). According to the CDC, this is the first known pandemic caused by the emergence of a novel influenza virus-new coronavirus that caused four pandemics in the last century (which is why the response to COVID-19 were adapted from existing guidelines developed in anticipation of a pandemic inlfuenza).

According to the CDC, reported the disease ranges from very mild (no reported symptoms in some cases) to severe, including diseases that lead to death. the elderly and people of all ages with severe health conditions seem. However, doctors still do not have a complete clinical picture COVID-19.

“I think there are two main questions,” said, a Yale Medical infectious diseases specialist and medical director of infection prevention at Yale New Haven Health. “First, we need to know how the virus is transmitted between people so that we can be more precise in our efforts to stop its spread. Second, there needs to be a better understanding of the pathogenesis of infection and resulting inflammatory response, so that the knowledge can encourage the development of therapeutic and preventive medicine. ”

There are also a lot more to learn about how COVID-19 spread-and how contagious it is. “Data is needed not only to better understand when people become sick shed the virus, but also that of body fluids containing the virus and how they may contaminate the surface and even the airaround them, “said Dr. Martinello.

The number of cases in the US continue to rise. This includes cases diagnosed in tourists, people who are close contacts of other known cases, and cases in the community that are imported, which meant there was no known source of infection.

proper testing is made widely available will be important in understanding how the disease is transmitted and the rates of infection and death properly. Besides COVID-19 testing conducted by the CDC in the US, state and local public health laboratories in all 50 states and the District of Columbia currently using COVID CDC-19 diagnostic test, although the number of tests available is limited at this time. Until there could be comprehensive testing for COVID-19, it is difficult to know how many cases have not been identified. “Testing is still very limited in Connecticut,” said Yale Medicine infectious disease specialist. “This is expected to change, but the testing should be prioritized for those who are most ill.”

Meanwhile, doctors in the US is keeping a close eye on the new virus. “With the new virus in a culture dish, they look at the biology and worked to make drugs to treat it,” said Yale Medicine infectious disease specialist. There are also a lot of effort was made to assess drugs in development (and some of the drugs available at this time) to determine whether they are useful for treating patients infected with COVID-19, added Dr. Martinello.

“There is a clinical trial to evaluate the potential of different therapies at the University of Nebraska Medical Center in Omaha, the first is remdesivir,” said Dr. Juthani. Remdesivir are antiviral medications, according to the National Institutes of Health, was previously tested in humans with Ebola virus disease and has shown promise in animal models to treat mer and SARS.

Meanwhile, China is currently testing a number of therapies in clinical trials. In mid-March, the National Institute of Allergy and Infectious Diseases (NIAID) announced the first human testing of an experimental vaccine called mRNA-1273 developed by the NIAID scientists and their collaborators at the biotechnology company Moderna, Inc. But it could take at least one year before the vaccine is available.

so far, the information shows the severity COVID-19 ranges from very mild infection (sometimes without symptoms reported at all) to severe to the point of requiring hospitalization. Symptoms can appear anywhere from 2 to 14 days after exposure, and may include:

You should contact your medical provider you for advice if you experience these symptoms, especially if you have been in close contact with people are known to have COVID-19 or live in an area with ongoing spread of the disease.

medical help immediately if you experience an emergency warning signs, including difficulty breathing or shortness of breath, persistent pain or pressure in the chest, a new confusion or ability to arouse, or bluish lips or face. This list is not inclusive, so consult your healthcare provider if you notice other alarming symptoms.

If you have traveled to the affected countries, taken a cruise in the last 14 days, or exposed to others with COVID-19, health officials will provide instructions on limiting your activities and movements up to 14 days for help keep the spread of the virus. “If you are recovering from a respiratory illness that you think might COVID-19, we encourage you to contact your doctor to see whether you should be treated for the flu and stay in your home continue to recover,” said Dr. Juthani.

patients and community members can call at 203-688-1700 (toll-free, 833-484-1200) if they have any questions. health officials admit that the outbreak has been stressful for everyone.

As with colds, vaccine flu will not protect people from developing COVID-19. However, while doctors learn more about the transmission, Dr. Vinetz said, “the best thing you can do at this point is take care of yourself the way you do to prevent yourself from getting flu, you know you can get the flu when people sneeze and cough on you, or when you touch a doorknob.-especially before eating and touching your face, and after going to the bathroom-and menghind ari others who have flu-like symptoms is the best strategy in thi s point. “

The CDC also recommends the followingPreventive measure:

As for the mask, there is little evidence to support the widespread use for people who are not sick. “We generally do not recommend the use of masks for the general public,” said Dr. Martinello. “Masks can provide a modest level of protection against liquids, including sprays from coughs or sneezes, and they provide some air filtration. But, because the mask does not provide a tight seal around the wearer’s nose and mouth, a lot of air inhaled and exhaled remain unfiltered. ” However, the CDC does not recommend face masks for people who have symptoms COVID-19, as well as for health care workers and others who may be caring for them. “Because we are experiencing a shortage of masks, it is important to keep the mask for health care workers and the sick patient in the emergency room to prevent other patients from the pain,” said Dr. Juthani.

While everyone should take precautions, some people looked at high risk for severe disease external reports out of China showed serious disease occurs in 16% of cases. Those most at risk include adults over the age of 60 years (the risk seems to be gradually increasing with age from the age of 40, according to WHO) and people with chronic conditions (such as diabetes, heart disease, and lung disease). People in this category must especially avoid crowded places and stock up on household items, foodstuffs, medicines, and other supplies in case they need to stay home for an extended period.

If you, or someone you care about, that felt overwhelmed with emotions such as sadness, depression, or anxiety, or feeling like you want to harm yourself or others, call 911, or the Substance Abuse and Mental Health administration Disaster Distress Helpline: 1-800-985-5990 or TalkWithUs text to 66746. (TTY 1-800-846-8517)

Since threats like COVID-19 can cause the circulation of misinformation, it is important to only trust information from leading health organizations and government sources such as the CDC and WHO. “US public health infrastructure is an essential resource for leading federal, state, and local response,” said Dr. Martinello. Because knowledge of the rapidly evolving new virus, you can expect recommendations change frequently.

State and local authorities make recommendations to slow the spread of the virus in the community. Guidelines from the White House called “the” stress avoiding social gatherings of more than 10 people; use the drive-thru, pick-up or delivery option instead of eating at a restaurant; avoid discretionary travel or shopping; and stay away from nursing homes and long term care facilities (because the parents are at especially high risk for serious complications if they get the virus).

Many experts also recommend the practice of voluntary “social distance,” which is the practice of maintaining a greater than normal physical distance or avoid direct contact with people in public areas to minimize exposure. The CDC says the disease can spread between people who are in close contact with each other (within about 6 feet). Although it is very important to keep a distance from people who are sick, many experts also recommend the practice of all the social distance and avoid large crowds, whether they were sick or not.

Global efforts are focused simultaneously on reducing the spread and impact of the virus, according to the CDC, and this has included major restrictions on travel. foreign nationals who have been in China, Iran, England, Ireland, and one of the 26 European countries in the last 14 days can not enter the United States. US citizens, residents, and their close family members who have been one of the countries in the last 14 days can get into the United States, but they are subject to monitoring and possible health quarantine for up to 14 days.

Anyone planning to travel out of the US should check the CDC travel advisories concerning several countries have confirmed cases of COVID-19. The latest CDC recommendations include avoiding all non-essential travel to China, Iran, South Korea, and most of Europe. CDC recommends that older adults and people with chronic medical conditions considering postponing any travel plans. “Given the declaration of a pandemic, it may make sense to avoid international travel in case of return becomes problematic,” says Dr. Juthani.

The CDC recommends that all travelers to postpone trips cruises, because the disease seems most likely to spread within infected close if a fellow traveler. It also suggests that people who are traveling in the US to practice preventive measures, because they may be at higher risk if they visit areas that have spread COVID-19 community.

guidance Meanwhile, specialist infection prevention at Yale New Haven Health (YNHH) has been provided for the screening of patients with acute respiratory infection to determine whether they had been to China or the location of the hard-hit others around the world in a few weeks before they got sick, or if they have been exposed to anyone who may have been hurt COVID-19. YNHH take warning approach by placing a mask in patients who may be at risk and placing them in a private space to ensure the safety of or all patients and staff.

An integrated team of Yale Medicine / Yale New Haven Health has worked hard to scale telehealth capabilities to be used by the provider. This means creating a plan to convert the in-person visits to video traffic where possible.

public health authorities strongly recommend everyone to get their annual flu vaccination if they have not already. “We continue to remain in the midst of a bad flu season,” said Dr. Juthani. In addition to preventing or reducing the severity of the flu, the vaccine will simplify the evaluation of patients with flu-like symptoms if case COVID-19 surface potential in the community.
