What are the coronaviruses: symptoms and treatment

Nichole Kerr



Coronavirus (2019-nCoV) was first given in Wuhan (China) in December 2019. We explain what coronaviruses are, symptoms and possible treatment.

It is the third time in the last 20 years, after SARS and MERS, that a human-infected coronavirus puts us on alert. The emergence of the new coronavirus 2019-nCov in China, capable of causing severe pneumonia and even death, has begun to spread throughout the world, causing great global concern.

Next, we will delve into what coronavirus is, what are the symptoms it produces and how it is treated.

What are coronaviruses?

Coronavirus is a common type of virus that belongs to a family of viruses that can cause different diseases. Coronaviruses were first discovered in the 1960s.

A coronavirus can infect both animals and people, however, they are much more common among animals. Although most coronaviruses are not dangerous, there are also those that can cause serious diseases. In fact, it is estimated that almost everyone gets a coronavirus infection at least once in their life and more likely when they are children or the elderly.

The origin of the coronavirus 2019-Nov

The first case of infection of the new coronavirus 2019-nCov was detected on December 31 in Wuhan, a city in southern China with more than 11 million inhabitants.

At first, it was believed that the new Wuhan virus had its origin in a local market where seafood and meat were sold since those affected agreed to have visited that market. However, in a new study, researchers have determined that the virus could have its origin in snakes. As for the type of snake, the scientists pointed out that there are two snakes that are common in southeastern China where the outbreak originated: the krait (Bungarus multicinctus) and the Chinese cobra ( Naja atra ). For their part, some experts criticized this study, saying it was not clear if coronaviruses can infect snakes.

After almost a month has passed, the virus has spread to at least nine other countries, including South Korea, Japan, Canada, the United States, and Germany among others.

The rapid transmission of the virus, popularly known as the “Wuhan coronavirus” has generated worldwide concern. In China, three cities have been quarantined, which has prevented the displacement of more than 20 million people. In addition, other countries are studying protection measures and are preparing for a possible epidemic.

What are the symptoms of coronavirus

Most coronaviruses spread similarly to the flu: through saliva, by infected people who cough and sneeze, by touching the hands or face of a person with a coronavirus, by touching objects that have been touched by people infected as door latches, etc …

The symptoms of coronavirus are similar to those of the flu:

  • Shortness of breath (trouble breathing)
  • Fatigue
  • Runny nose
  • Cough
  • Headache
  • Sore throat
  • Fever
  • General discomfort

The coronavirus can begin to manifest itself a week after being infected by the virus. Most symptoms appear between three and six days after infection.

The highest risk groups, such as the elderly and children, can develop more serious diseases when they are infected with the coronavirus, such as pneumonia, severe acute respiratory syndrome, and kidney failure and can even lead to death.

If you already experience underlying anxiety, COVID-19 more than likely amplified these associated symptoms. While there’s no magic fix to anxiety, CBD products have shown to ease symptoms in preliminary clinical trials along with numerous anecdotal accounts. So, while further study is warranted, you as a consumer can begin taking advantage of CBD in its many consumable forms now.

What steps to take to prevent coronavirus

There are currently no vaccines to prevent human coronavirus infections. However, both China and the United States are working on the creation of a vaccine that prevents the spread of this new virus, which is expected to be ready in three months.

For its part, the World Health Organization recommends a series of prevention measures to reduce the risk of contracting or spreading an infection:

  • Wash your hands frequently with soap and water for at least 20 seconds.
  • Avoid touching your face, nose or mouth with unwashed hands.
  • Avoid close contact with sick people.
  • Clean and disinfect frequently touched surfaces.
  • Cover your nose and mouth when you cough or sneeze with a tissue. Then discard the paper and wash your hands.
  • Stay home when you are sick.

In another article, we already saw some products to prevent this type of infectious respiratory disease such as coronavirus.

How coronavirus is treated

Scientists are taking advantage of past experience to determine how to handle this rapidly spreading disease. Effective treatments to combat coronavirus are not yet known. At the moment, there is no vaccine to prevent the spread of this virus. Therefore, although travel is not restricted, the World Health Organization recommends that countries take extreme precautions and pay special attention to travelers.

For its part, China has quarantined the people of Wuhan and has also closed transport to the city and its surroundings. In addition, the construction of a hospital dedicated exclusively to the treatment of coronavirus has begun and the work is expected to be completed in less than 10 days. The hospital will have beds to treat 1,000 patients.

Hip-Hop Celebs Who Had Plastic Surgery, from LA To Denver To NYC





If you can make something on your body look better, then why not do it!

That is the motto most women and men in the entertainment industry are going by. And true to this motto, some Hip-Hop artists have come out looking better and feeling more confident in their artistry.

A lot of people in the world today are open to breast and buttocks surgery in addition to facelifts, liposuctions, nose jobs, and even hip enhancements, among many more. Hip-hop celebs happen to be in the limelight and hence, new changes are spotted the moment they hit the red carpet.

Want to find out if your favorite rapper has had something done? Read on to find out.

Cardi B

The New York female rapper has been known to be very vocal about her life and holds nothing back. If it bothers her, you will know. Heard of the new parody going round with a lady shouting ‘coronavirus,’ well then that might as well be our beloved Cardi B.

Belcalis Marlenis Almanzar, aka Cardi B, was raised in South Bronx, and before hitting stardom, she did a couple of odd jobs to survive. One of those jobs was a clerk, and the most known career that put her on a map was being a stripper. Soon after she took to TV on Love and Hip Hop: New York edition, then shorty dropped her hits ‘Bodak Yellow’ and ‘I Like It,’ which saw her rise quickly on the billboards.

The artist has had her breast augmentation, implants in her butt, and, most recently, liposuction [more here]. The lipo took a toll on her as she had to miss a few concerts and bookings, but we have to admit, she looks pretty amazing with her new flat tummy.

Nicki Minaj

Yet another NYC product who has been under the knife is Nicki Minaj, although she denies it.

Most will agree that the transformation was worthwhile. And if you take a look at Nicki’s before and after picture, you can see the work she has had done. For starters, she has had breast and buttocks surgery that is undeniably flawless. Secondly, she has allegedly has had a nose job back in 2009, tooth surgery, butt implants, boob job, and most recently botox.

This list is quite something. Regardless Nicki looks stunning and feels great about her body telling by her choice of clothing — she wants to show it all irrespective of what the tabloids say.

Lil Kim

One of the oldest Hip-Hop artists we have in the industry is Lil Kim, and this list would not have been complete without her.

The star has had a few standard procedures like the plastic surgery Denver Coloradans tend to get.  These are breast enhancements, rhinoplasty, and facelifts. She denies all operations, but let’s be real, even your skin cannot jump shades lighter unless something is done. And also, boobs do not just grow out of the blues; the knife must have had a role to play!

Her makeovers are, however, speculating a bit of traction that she is perhaps taking it a little too far. With the skin lightening and some things seeming off, plastic surgeons in Atlanta and elsewhere could take one look at her and know something is off. But she still denies it firmly.

All in all, we cannot deny that the star seems happy with her new look, irrespective of what people are saying.

Remy Ma

Nikk Minaj nemesis, Remy Ma, also happens to make it to this list. She also made a small screen showing on the Love and Hip Hop: New York.

This was after serving time and coming out looking better than never before.

She came out looking lean and toned out but still rocking her signature colored wigs. Nikki Minaj was the one who created the speculations that Remy Ma might have had some work done on herself, but to date, no pictures can prove it. Regardless, she still makes to this list such that when those pictures finally get here, you already got the news.

Kanye West

We had to include at least one guy on this list to even the playing ground. Yes, men can also go under the knife, and Kanye admitted to having done so during an interview with TMZ.

Kanye had liposuction done on his body that gave him a sturdy frame. He simply did not want people to call him fat as they did to his brother-in-law at his wedding. His surgery was successful, but the aftermath left him addicted to opioids that he also admitted in the interview. But he has fully recovered from it.

This is not an isolated case, as thousands of opioid addicts started right after plastic surgery. Plastic surgeons in Atlanta and all over America, therefore, prescribe the drug with more caution nowadays.

Husband to Kim sure looks good in his new body and is not ashamed of owning it.

Take Away

People have been doing whatever makes them happy since time immemorial, and so if you desire to get your nose fixed or your butt lifted, then why not! You only have one life to live. So do it and do it right.

Membrane filters you need to know and their properties

Bryan Nesbit



Membrane filters or commonly known as “membranes” are microporous membranes with specific pore size ratings. It is also called a sieve, microporous filter, or screen. Cellulose acetate membrane filter preserves or filter particles bigger than the pore size. If there are particles slighter than the pore size, other mechanisms will be used. There are different types of membrane filters, such as nylon, cellulose acetate, mixed cellulose ester, or MCE membrane filters. Here are more membrane filter types and their attributes.

The mixed cellulose ester

MCE is composed of cellulose acetate and nitrocellulose. It has a high porosity and can provide a higher flow rate. It also has a high level of protein binding, which can be prohibited by pretreatment or application. MCE is a standard membrane that can be used in many laboratory applications, such as filtration and sterilization of biological fluids, pollution analysis, microbiology, and air monitoring. The membrane is able to be converted into transparent to view the particles collected during the filtration process.

Cellulose acetate-

coated cellulose acetate consists of cellulose acetate cast on a non-woven polyester carrier. It has a non-fiber releasing ability, and the protein binding level associated with nitrocellulose is low. It also has a low level of static charge and chemically enhances compatibility with low molecular weight alcohols. The coated cellulose acetate is used as a pre-filter or clarification filter.

Hydrophilic PTFE

Hydrophilic PTFE has characteristics described as having the greatest resistance to chemicals and pH. The membrane has a high level of flow rate and almost no water-extractable. When the membrane is wetted with water, it is transparent to the naked eye, so it is very suitable for use in HPLC, organic solvents, and other aqueous mixtures.


PTFE The characteristic of hydrophobic PTFE is that it has a high porosity is very thin and behaves like a monolithic retention membrane. It also has a passive effect on most corrosive chemical solvents, alkalis, and strong acids. The membrane traps water-containing aerosols by sterilizing the gas. It is also used for gas and air discharge so that gas can freely pass through the membrane, and at the same time prohibit liquid from entering. This protects the best samples and vacuum pumps. In addition, hydrophobic PTFE clarifies and sterilizes strong acids and other solvents that are incompatible with other membrane filters.


nylon membrane filters are made by impregnating polyester fiber webs with polymers made of nylon. This makes the membrane durable, heat-resistant, and essentially hydrophilic. Because it is hydrophilic, it is suitable for alcohol and aqueous samples. The membrane filter can be used to sterilize, filter, and clarify organic aqueous solutions.

Cellulose acetate

The membrane filter is composed of diacetate and cellulose triacetate. It is characterized by high strength and low electrostatic charge. The advantage of using it is that it can be repeatedly disinfected without losing its integrity or changing its bubble point. Associated with MCE membrane filters in stipulations of their solvent confrontation to alcohol molecular weight increase at low levels.  Cellulose acetate is used to enhance the recovery of positive organisms and filter enzyme solutions. It is also used for cytological diagnosis and receptor binding research.
