COVID-19: Main Symptoms

The three main symptoms of “new crown”: are fatigue, brain fog and muscle pain, the specific manifestations vary from person to person. Other more common persistent symptoms include shortness of breath, chills, body aches, headache, joint pain, chest pain, cough, and persistent loss of taste or smell.

 Forgetfulness, anxiety: “I feel useless”

Many people with long-term symptoms report cognitive impairment or memory loss that affects their ability to make everyday decisions, speak, follow directions and drive, and impair their quality of life.

Xiao Liu (pseudonym) works in British media. Three years ago, he suffered from depression. He largely recovered before contracting Covid-19 in November 2021 and has stopped taking antidepressants. But after she contracted Covid-19, the depression returned. The doctor assessed and judged that one of the symptoms of the new crown-brain fog persisted.

“After I got the new crown, I felt that I was ‘brainless’, I didn’t want to do anything, and I was extremely anxious.”

It starts with cold-like symptoms, headache, cough, fever, and loss of taste and smell. There are also chest tightness, shortness of breath, fatigue, insomnia, loss of appetite, forgetfulness, inability to concentrate, unresponsiveness, anxiety, etc.

“The overall condition is not good, and the weight has lost four kilograms”

After Xiao Liu fell ill, the children became sensible. I get up every morning looking for a school uniform to wear, and my 11-year-old will scramble eggs, eat breakfast, and go to school alone. My brother was hungry at night, so he cooked instant noodles and ate them together.

Xiao Liu remembers coughing for three weeks, being bedridden for a month, and then taking a long sick leave of more than three months.

“I couldn’t get out of bed to cook at all. The children ate takeaways every day, and my mouth ulcers had developed for a long time. Fortunately, some friends helped us and often brought us home-cooked food. At that time, the volunteers in the community even gave me anti-inflammatory drugs. Depression. Come to my house and make sure I take it on time. My family doctor advised me to call my psychiatrist again.”

“The biggest motivator for me was the several home visits from the social worker in charge of child welfare. The kind help made me extremely anxious and insomniac, and I felt like an incompetent mother who couldn’t do even the most basic things to take care of her children.” Covid has cost me! It’s unacceptable to me.”

“Regular doctor consultations and cordial greetings from unit leaders also made me feel like I was a burden. I didn’t want to be sick all the time. Everyday burnout and bedridden made me feel like I was useless.” “

For a long time, Xiao Liu felt that he had Alzheimer’s disease. Can’t remember anything, looking for something every day. It takes a few repetitions to understand what the doctor says. Sometimes after calling in the morning to confirm, call in the afternoon to ask.

“Sometimes I don’t know if I have taken medicine or not. Once I enter the kitchen, I forget what I am doing. I look at the pills with a water glass and ask myself if I just took the medicine or not?”

Because of the confusion caused by many small things, Xiao Liu deeply doubts his ability to do things. She feels that she must first learn to forgive herself and accept herself who is often tired and forgetful now.

Xiao Liu said that now he wants to make himself happier and more optimistic by doing one small thing every day. Doctors want to taper off antidepressants over a year.

Fatigue: “Three hours of sleep when I get back from the store”

Severe fatigue is by far the most common symptom of COVID-19. Other symptoms include muscle pain, hearing and vision problems, headaches, loss of taste and smell, damage to the heart, lungs, kidneys, and intestines, diarrhea, and mental health problems, including depression, anxiety and distraction, and stupor.

Before being diagnosed with “coronavirus”, she had been suffering from persistent fatigue, fever, and loss of smell and taste for months, for which she consulted several doctors of different specialties.

At first, my temperature rose slightly, I felt dizzy, and then my throat started to hurt. A day later, my fever reached 38.5°C. 

Later, I went for a checkup and received treatment. 

After three weeks of conventional viral infection treatment, tachycardia was found, while fatigue symptoms did not decrease.

Frequent blood tests, blood pressure measurements, and lung monitoring are performed. After taking antibiotics and vitamins for three weeks, the treatment failed, and he underwent ENT, pulmonology, cardiology, virology, rheumatology and immunology tests. Found chronic sinusitis, and heart adhesion, but not sure if it is caused by the new crown, it was still there before.

After a month, blood cell counts stabilized, but mental and physical fatigue and fever persisted.

For seven months, I was unable to concentrate, disoriented, felt hot, shivering, tired, didn’t know when it was going to pass, and felt scared every day.

At the doctor’s advice, make a “resurrection” plan, start walking, but take breaks from time to time, sleep at least three hours after going to the store or spend an hour in front of the computer.

Feeling changes, headaches, fatigue and brain fog are just a few of the symptoms of ‘coronavirus’

 Cognitive Function and Brain Fog: “IQ Decreases…”

“I’m not back to normal, from a cognitive standpoint, I’m not back to where I was before the coronavirus, in terms of focus, agility, flexibility… a year and a half later, I feel like I’ve only lost 30-40 %”. she says. % has been restored. I’m not the same as before, my IQ has dropped. “

“After a year and a half, after a lot of hard work, a lot of self-discipline, and all things considered, my condition has improved. I have anxiety (cognition) and I won’t fully recover, but I’m slowly accepting the possibility.”

Flocked Swab

Flocked Swab

Nylon flocked swab

Made of nylon fibre flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner.

Increasing the efficiency of collection and release of cellular and fluid samples.

So that there is no absorption hole in the entire collection area of ​​the swab.

The collected sample does not disperse and remains in the fibre, facilitating faster and more efficient elution.

Traditional spun cotton swabs cannot completely collect and elute the sample, while flocked swabs can elute more than 95 per cent of the sample collected.

So the use of flocked swabs has great advantages for a variety of sample collection applications.

Because most of the testing tools used for nucleic acid testing are disposable sampling swabs, we usually see more nasal swabs and throat swabs.

Improve analytical sensitivity, no sample residue, and speed up sample processing.

PS stickers come off easily. Suitable for cervical, nasopharyngeal, oral, forensic collection systems and DNA collection, etc. Individually packaged.

Flocked swabs are biocompatible and ideal for PCR work.

PCR is compatible, free of RNase and DNase, so the new flocked swabs are ideal and a good choice for scientists working with PCR technology.

Flocked swab sampling is more comfortable and easier to use;

CellMedical’s flocked swabs use the existing technology “spraying technology”, which is to vertically attach millions of nylon fibres to the head of the medical swab shaft through electrostatic charges in the flocking hair.

The vertical nylon fibres resemble a soft brush.

During sampling, the user will have no foreign body sensation.

In addition, different parts have different breaking points of the flocking swabs used, and the thickness of the swab rod is also different.

So there is a big difference in softness.

For example, for nasal swabs, the upper end of the swab rod is thin and soft, and the breaking point is also relatively back.

During the outbreak of the new coronavirus pneumonia, while everyone is doing personal protection, they are also very concerned about the epidemic situation.

Originally, the social season in winter and spring was a period of the high incidence of common colds and flu, and the most important means to control the epidemic was to screen out the real patients with new coronary pneumonia from many respiratory patients.

The following small series will introduce some common virus sampling detection methods for you.

Nasopharyngeal swab

Collect nasopharyngeal swab specimens within 3 days of the onset of the patient as much as possible.

Measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be at least half the length from the earlobe to the tip of the nose so that the swab stays in the nose for 15 ~30 s.

Gently rotate 3 to 5 times, quickly put the swab into a sample collection tube containing 2 ml of lysis buffer (the same as the lysis buffer in the nucleic acid extraction kit) or a cell preservation solution containing RNase inhibitors, and insert the swab.

Then break the sterile swab rod near the top, screw the cap tightly and seal it with parafilm.

Oropharyngeal swab

Collect throat swab specimens from patients within 3 days of onset as much as possible. It is advisable to use a sterile flocked swab for sampling, wiping the posterior pharyngeal wall with moderate force, avoiding touching the tongue; quickly put the sterile swab into the collection tube used for collecting nasopharyngeal swabs, and break it near the top Sterile swab rod, screw cap tightly and seal with parafilm.

Anal swab (feces)

For patients with gastrointestinal symptoms such as diarrhea in the early stage of the disease, an anal swab should collect a stool sample (soybean size) of 3-5g.

The specimens were collected in a screw-cap specimen collection tube containing 2 ml of normal saline (RNase inhibitor can be added if available) and sealed with parafilm.

How to collect nasopharyngeal swabs

There is absolutely no need for the sampler to stand directly opposite the patient. Regardless of whether the patient is sitting or lying, right-handed patients can stand on the right side of the patient, and left-handed patients can stand on the left side for sampling operations.

The advantage of standing on the side is that if the patient has a cough, sneeze, etc., it can be avoided in time.

After the nasopharyngeal swab is passed through the nostrils.

It is perpendicular to the coronal plane of the head or the face and penetrates deep from the inferior meatus to the posterior wall of the nasopharynx, and it is enough to feel the wall.

The nasopharyngeal swab enters the nasal cavity to a depth of approximately the distance from the tip of the nose to the earlobe (see figure).

The “American Society for Microbiology Clinical Microbiological Specimen Submission Guidelines. ” We ask to twist the nasopharyngeal swab on the nasopharyngeal mucosa, hold it for 10-15 seconds, and then take out. Children’s cooperation is poor.

We generally take out the Flocked swab in three to five seconds after fully twisting it 2-3 times.

Except for paying attention to the depth of the swab. We should also note that there is always the habit of having the patient lift their head completely, bend the swab, and take a sample. This is wrong.

In fact, the above approach is wrong. This operation will cause the swab head to stay in an incorrect position. And the final sample obtained is not a standard nasopharyngeal swab specimen.

Flocked refers to the process of applying multiple lengths of fibers to the surface of the adhesive coating.

It is basically the same as the cotton swab except for the material.

It can also be said that the flocking adheres to the head of the flocked swab. It is a flocking swab, but it is different from cotton swabs in that it is a disposable sampling swab composed of nylon short fiber fluff head + ABS plastic rod.

COVID-19 is an infectious disease,a respiratory disease.

COVID-19 variants_Omicron

The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.

We must do a good job in vaccine injection and virus swab testing is the top priority.
According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.

The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.

According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.

At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.

This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.

The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.

The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.
The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.

The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.

Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.

However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.

What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;

The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.
This situation may happen 2-14 days after you touch the virus that causes COVID-19.
Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.
Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.
If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

Oral Swab Stick

Oral Swab Stick

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.
