No one wants to be caught off guard by a second coronavirus outbreak if there happens to be one, and with some medical professionals saying there is a high possibility of another outbreak on the horizon, it's best to be prepared.
So what will you need to be prepared? Basically, everything you rushed to by amid this coronavirus outbreak. To make things a little easier, I have compiled a list of the five things that everyone should stock up on just in case there is a second wave of coronavirus. If a second wave does hit, these items will be a lot harder to find, so I'd be very mindful of when they come into stock and if they do grab a few spares just in case.
What are the items? They are nothing out of the normal, just the general hand sanitizer, face masks, paper towels, toilet paper, and a chest freezer. If you are interested in seeing the pricing for each of these items, I have compiled a list in the entirety of this article.
The reopening schedule for America differs from state to state, but could it be too early in general to reopen the country? Could everyone be jumping the gun?
According to former Food and Drug Administration chief, Scott Gottlieb, the virus isn't contained yet, which means that "normal" life is still quite far away. Gottlieb said during an interview with Face the Nation, "That doesn't mean we can't go out and start doing things, get back to some semblance of a normal life, but we need to do things differently. We need to define a new normal." Gottlieb also warns that as restrictions begin to ease, people shouldn't be surprised if they see a second surge in coronavirus cases.
Gottlieb also states that it's likely the virus will continue to circulate the country, and if states prematurely open, it will have a big impact on the overall spread. The former FDA chief says that it's likely we will see a resurgence of the virus in the fall, which could be particularly more dangerous in certain cities and areas. "If we do that on a broad basis across a whole population, it can have a big impact on spread. The virus is likely to continue to circulate. We're likely to have this slow burn through the summer and then face renewed risk in the fall that we're going to have bigger outbreaks and potential epidemics in certain states and cities."
A new study out of Singapore has indicated that coronavirus patients might not be infectious for as long as previously thought.
The study out of Singapore has referenced research out of Hong Kong that indicated that a COVID-19 patient could be contagious as early as 2.3 days before symptoms begin to show. That same study said that the contagious levels of the patient begin to decline within 7 days. However, the new study from Singapore says that patients won't be infectious 11 days after the onset of symptoms, even if the patient still tests positive for COVID-19.
The study states, "Active viral replication drops quickly after the first week, and viable virus was not found after the second week of illness despite the persistence of PCR detection of RNA. These findings are supported by epidemiologic, microbiologic, and clinical data." This study might allow hospitals to revise their discharge criteria for patients, and also allow for resources to be focused on patients that are suspected of COVID-19 infection.

The World Health Organization (WHO) has officially suspended trials being conducted on the controversial anti-malaria drug hydroxychloriquine.
This decision has come only days after a massive study published in The Lancet indicated that the drug hydroxychloriquine was actually having negative effects on coronavirus patients. The study concluded that using the drug on coronavirus could even increase the patients' chance of dying, and not reduce it. WHO chief, Tedros Adhanom Ghebreyesus, said, "The Executive Group has implemented a temporary pause of the hydroxychloroquine arm within the Solidarity Trial while the safety data is reviewed by the Data Safety Monitoring Board".
This decision by the WHO has also been made days after President Donald Trump announced he had finished his program of hydroxychloriquine. WHO emergencies chief, Michael Ryan has said that this decision to suspend the trial is an act of precaution. On top of that, WHO chief scientist, Soumya Swaminathan, said the decision was "a temporary measure". The chief of the WHO did stress that other drugs in the Solidarity Trial will continue being tested. "The other arms of the trial are continuing" said, Tedros Adhanom Ghebreyesus.
Almost all of the states are beginning to slowly reopen amid the coronavirus outbreak, which means citizens in these states need to know the safest places they can go to avoid contracting the virus.
According to the University of Massachusetts Dartmouth associate professor of biology Erin Bromage, who recently spoke to CBS News, said "Every interaction that we have with another person, another household, gives an opportunity for the virus to find a new home, and to get into a new household." One of the least concerning places you should worry about is being outdoors alone, or with the people you have quarantined with. As you know, these people are far less likely to have contracted the virus from somewhere else.
The riskiest place to be is indoors with a bunch of people you don't know, and it's most likely that the place you are in has poor airflow, which then raises the risk of contraction even further. This rule of thumb doesn't go for every indoor place. For example, if you are sitting alone in a quiet corner of a building and not conversing with anyone than there's a lower chance of you getting the virus than if you were at a bar conversing with a lot of people.
A massive study that involved more than 20,000 coronavirus patients from the UK across 208 hospitals found some fairly critical information in regard to common symptoms and main risk factors.
According to the study, the four main risk factors that increase the likelihood of a coronavirus victim developing a more severe symptoms are age, sex, weight and underlying illnesses. These findings back up most of the preliminary studies that were being conducted throughout the early days of the virus. The study also found that the average age of someone admitted to hospital with symptoms was age 73, and that 60% of all the coronavirus patients involved in the study were men.
It was also discovered that coronavirus patients that already had underlying health issues were more likely to develop coronavirus symptoms - the most common was heart disease. On top of that, the study details that "increasing age, male sex, and comorbidities including chronic cardiac disease, non-asthmatic chronic pulmonary disease, chronic kidney disease, liver disease and obesity were associated with higher mortality in hospital."
Being an astronomer means you sometimes find things in space that you or no one else has ever seen before.
In a new paper published in Nature Astronomers details one of those findings, and funnily enough, the finding is a galaxy that is shaped like a donut. This galaxy is called R5519, and astronomers estimated that its distance is 11 billion light-years away, which means what we are observing happened 11 billion years ago. According to Dr. Tiantian Yuan, lead author of the study, "It is a very curious object that we've never seen before. It looks strange and familiar at the same time."
So what is this galaxy doing exactly? Well, researchers believe that it's working like a star factory, but its producing stars at a rate that's 50 times greater than our Milky Way galaxy. Researchers also believe that this galaxy formed differently than a typical galaxy, which is usually when a galaxy forms on its own without any outside influence. In the instance of R5519, researchers believe that this galaxy is a "collisional ring galaxy".
New York Governor Andrew Cuomo has admitted this past Monday that all coronavirus projects made by experts were "all wrong".
Cuomo spoke to reporters on Memorial Day and said that he's out of the speculation business because "we all failed at that business. Right?". He continued, and went on to say that all early national experts were all wrong and that "we all failed". Here's his full statement, "Now, people can speculate. People can guess. I think next week, I think two weeks, I think a month. I'm out of that business because we all failed at that business. Right? All the early national experts. Here's my projection model. Here's my projection model. They were all wrong. They were all wrong."
Throughout Cuomo's statement, he mentioned the statewide criteria that specific regions need to hit for quarantine and safety measures to be reduced. The criteria, which can be found here, states that regions must have a decline in hospitalizations and deaths, while also meeting contact-tracing and testing benchmarks. Cuomo didn't want to give a date when he thinks New York could reach those benchmarks, hence his previous statement of being out of the "guessing business".
Researchers have managed to find infectious traces of COVID-19 in samples of patient feces, indicating that hospitals need to take high levels of care in disposing of fecal matter.
According to a report published in Emerging Infectious Diseases, Chinese researchers were able to isolate live COVID-19 virus from fecal samples. The researchers noted that fecal samples contained a higher load of virus DNA the respiratory samples, and that as a patient case worsened, the scientists were able to detect SARS-CoV-2 in four fecal samples.
The researchers also collected fecal specimens from 27 other patients, 11 of which tested positive for virus RNA at least once. The scientists were able to isolate live SARS-CoV-2 from the patients' fecal samples, "indicating that infectious virus in feces is a common manifestation of COVID-19". The authors of the report noted a 2004 study that suggested sewage lines led to the aerosolization of feces contaminated with SARS-CoV-1, which causes SARS. Of the 329 residents living in the Hong Kong building 42 died.
Newly published research has highlighted the differences between coronavirus patients and flu patients.
The research which was published in the New England Journal of Medicine concentrated on how the coronavirus causes extreme damage to lungs, and how that damage compares to that of a flu patient. The research looked at seven lungs from COVID-19 deaths, and compared the lung tissue from the COVID-19 patients to that of seven patients that died of pneumonia caused by the flu. Both COVID-19 patients' lungs and flu patients' lungs had severe damage, but researchers noticed that the coronavirus attacked the lining of the blood vessels in its victim - marking a key difference between the two groups.
On top of that, researchers were able to find nine times as many microscopic blood clots inside the COVID-19 patient's lungs, than in the flu patients' lungs - marking another key difference. According to Steven J. Mentzer, who autopsied the lungs for this study, "Patients who do fairly well have a purely respiratory disease, and the patients who have trouble have a vascular component as well."
