Monkeypox Virus Outbreaks Are Containable

Monkeypox Virus Outbreaks Are Containable

Posted on by

Monkeypox Virus Outbreaks Are Containable, WHO said available details indicated that human-to-human transmission was occurring among people who had close physical contact with symptomatic cases. The patient’s symptoms were similar to those observed in smallpox patients in the past but were less clinically severe.

These confirmed and suspected cases are mainly from the United Kingdom, Spain and Portugal, with the rest in Australia, Belgium, Canada, France, Germany, Italy, the Netherlands, Sweden and the United States.
 The incubation period for monkeypox is usually 6 to 13 days, but it can be between 5 and 21 days.
However, Nick Finn, deputy director of England’s National Infectious Service, stressed that monkeypox does not spread easily from person to person and that the overall risk to the public is low.
An expert from China’s disease control system also told Caijing·Great Health that the spread of monkeypox between people can be said to be very limited, mainly through secretions and other transmissions, and the risk of causing an epidemic is very limited.
How serious is a monkeypox infection?

Before the current outbreak, monkeypox cases scattered in the tropical rainforests of central and western Africa.

Monkeypox Virus VTM Kits

Monkeypox Virus VTM Kits

There are two distinct clades of monkeypox viruses, the Congo Basin clade and the West African clade. Monkeypox, caused by the Congo Basin clade virus, has reported a mortality rate of up to 10.6%; while the West African clade virus, which usually causes less severe disease, has a case fatality rate of 3.6%.
In this outbreak, all cases with samples confirmed by polymerase chain reaction (PCR) testing were determined to be infected with the West African branch, meaning relatively low mortality.
The genome sequence of a swab sample from a confirmed case in Portugal showed that the monkeypox virus responsible for the current outbreak closely matched cases exported from Nigeria to the UK, Israel and Singapore in 2018 and 2019.
Initial symptoms of monkeypox infection include fever, headache, swelling, back pain, muscle aches and general weakness. Infected individuals initially have generalized erythema or rash, which then develops into papules on the trunk, face, palms, and soles, which then develop into cysts, which form pus scars and scabs. Sometimes a bit like chickenpox, the infection lasts 14 to 21 days and usually goes away on its own.
The virus can enter the body through broken skin, the respiratory tract, or through the eyes, nose, or mouth. Evidence suggests that the highest risk of infection is in people who have had close physical contact with a symptomatic monkeypox patient.
Of the first nine cases of monkeypox confirmed in the UK, six had had sex with men.
To date, severe cases are more common in children and immunocompromised people, especially those with HIV, and are related to the degree of exposure to the virus, the patient’s health status, and the severity of complications.
Hans Kruger, WHO Regional Director for Europe, also said: “Monkeypox is usually a self-limiting disease and most infected people recover within a few weeks without treatment. 

How to get out of Africa and into Europe?

Confusingly, monkeypox occurs primarily in the rainforest regions of central and western Africa. For example, the US recorded two cases of monkeypox in 2021 and the UK reported seven cases, all imported to and from Nigeria. travel history.
However, in this outbreak, it is unusual for confirmed and suspected cases reported in several countries without any travel history to monkeypox-endemic areas.
Australia, Canada and the United States are also among the non-endemic countries reporting monkeypox cases. Health authorities in New York City, home of the United Nations, are also investigating a possible case. A patient at a hospital tested positive on May 19, local time.
These cases are atypical, Hans Krueger said. All but one were not related to travel to monkeypox-endemic countries.
WHO believes that there is an urgent need to raise awareness of monkeypox and implement comprehensive measures to detect and isolate cases, trace contacts, and provide supportive care to limit further spread.

How to stop the spread.

“China has not reported any cases of monkeypox, nor has the virus been found in animal hosts. The current focus is on preventing imported cases,” Tan Wenjie, a researcher at the Chinese Center for Disease Control and Prevention’s Institute for Viral Disease Prevention and Control, said in an interview with the media. (Transport medium )
According to the above-mentioned experts of China’s CDC, at present, the measures to prevent the importation of the monkeypox virus are very strict.  Import squirrels, rabbits and other rodents. The possibility of monkeypox being introduced by animals brought by inbound passengers is unlikely and the public need not worry.
Specifically, researchers don’t yet know the animal reservoir of the monkeypox virus.
Since 1970, the monkeypox virus has had sporadic outbreaks in 10 African countries. This is a DNA virus in the genus Orthopoxvirus of the Poxviridae family. In 1958, a group of captive monkeys transported from Africa to Copenhagen, Denmark for scientific research developed the vesicular disease. European scientists isolated the monkeypox virus from monkeys in the laboratory, hence the name “monkeypox virus”.
In 2017, Nigeria experienced its largest outbreak on record. At that time, there were 172 suspected cases, and 75% of the patients were men, aged 21-40. Since then, Nigeria has continued to report monkeypox cases.
 Of these, 241 were confirmed cases, including 8 deaths (case fatality rate 3.3%). From 1 January to 30 April 2022, 46 suspected cases were reported and no deaths were recorded.
In 2003, there was an outbreak in the United States, the first time the disease had emerged outside of Africa. The patient was infected due to close contact with marmots. Marmots were infected by various small mammals imported into the United States. There were 81 cases at the time, but there were no deaths.
The cases of monkeypox infection have emerged in multiple countries, and researchers suspect that transmission may have continued for some time because all but one of these cases were not related to travel to monkeypox-endemic countries and were geographically dispersed in Europe and elsewhere.

Matthew Kavanagh, acting deputy executive director of WHO’s AIDS agency, stressed on May 22 that leaders urgently need to strengthen their pandemic preparedness. Including building stronger community-led capacity and human rights infrastructure to Support an effective and de-stigmatizing response to the outbreak.

The above-mentioned experts in the disease control system explained to Caijing. 

However, the “early detection” of the monkeypox virus is difficult. The above-mentioned experts in the disease control system said that it takes a certain period of time for monkeypox infection to have clinical symptoms and thus be discovered, which is different from the emergence of viral symptoms in respiratory infections.

Nylon flocked swab

Innovative jet embedded nylon modern technology can improve the effectiveness of the example collection from the client to the largest degree. The nylon has stuck vertically and uniformly to the surface of the swab pointer, which can boost the effectiveness of accumulating as well as releasing cells as well as liquid samples. Improve analytical level of sensitivity, No sampling recurring, and can speed up the specimen therapy. PS sticker label is very easy to break short. Adjusted to cervix wombs, nasopharynx, oral cavity, Forensic Purchase System as well as DNA accumulating, etc. Private stuffed.

Features

1. Flocked swabs provide the best sampling effect. Groups of swabs are the best choice for rapid diagnostic testing because they can better collect cells or organisms at the collection point and quickly release intact cells.

2. Enhance the sensitivity of diagnosis. The patented flocking technology turns each strand of fibre into a velvet brush, resulting in hundreds of thousands of contact points, which can better collect and release samples. The increase in the number of target cells (compared with non-flocking swabs) helps to improve the sensitivity of rapid diagnostic tests.

3. The flocking swab with rapid elution of CellMedical is closely combined with the handle and does not contain the internal fabric or other inner cores that absorb the samples, which can collect and retain more samples. This can not only provide a better sample size but also make the sample released into the liquid medium more quickly and completely.

4. Proprietary long flocking fibre flocking swab the proprietary long flocking fibre forms a network structure, which can collect and retain more specimens than traditional cotton, polyester or man-made fibre swabs. The inner core of an ordinary cotton swab will easily lock the sample, making it difficult to elute and pour it into the medium.

5. Convenient handling and transportation. Most oral, oropharyngeal and nasopharyngeal flocking swabs have prefabricated breaking points, so you can easily break the handle before putting the swab into the vial. Sterile flocking cotton swabs will also be equipped with dry transport tubes and media filling transport tubes and other transport materials. After sampling, the storage and transportation can be completed conveniently.

In a word, a flocked swab can better meet the sample collection needs of laboratories, hospitals and other institutions. It is the preferred tool for sample collection and elution.

Flocked Sterile Swabs

Flocked Sterile Swabs

Disposable sampling swabs, We believe you are familiar with them in the past two years because most of the testing tools used for nucleic acid testing (PCR tests) are disposable sampling swabs.

Usually, we see most nasal swabs and throat swabs, and the sampling swabs we commonly use are flocking swabs.

The flocking swab is a disposable sampling swab composed of a nylon short fibre fluff head and abs plastic rod.

Recently, there have been many concerns about rapid antigen detection on the Internet.

One of them is that if the “single-use sample collection swab” (sampling flocked swab) used in the antigen test is “non-sterile” and “non-sterile”. Bacteria” products. There are risks when using it.

Citizens disinfect the sampling swab with alcohol before conducting antigen testing at home?  ( Alcohol disinfection is not advisable)

Experts and industry insiders say such concerns are unnecessary as long as qualified products are available through formal channels.

Discard damaged or contaminated swabs.

Specimen collection sterile flocked swab

Specimen collection sterile flocked swab

Are there risks to using “non-sterile” “non-sterile” Specimen collection swabs?

There are two main issues that netizens worry about:

One is to worry about the “bacteria” of the sampling swab, which will affect the results of the antigen test, such as “false positives”;

The second is to worry about the “bacteria” of the sampling swab. During the sampling process, “bacteria” will enter the human body with the sampling swab and affect health.

Nasopharyngeal swab test

Nasopharyngeal swab test

Regarding the effect of “bacteria” sampling swabs on antigen test results, experts said that this is a misunderstanding caused by confusing bacteria and viruses.

You know, the antigen test “looks” for the antibodies produced by people infected with the new coronavirus.

The display window of the reagent strip contains a protein that recognizes the antibody, like a dam, blocking the colloidal gold that binds the antibody to the virus. So it appears red in the display window.

Therefore, even if the sampling swab contains “bacteria”, the kit will “ignore” it and focus on “finding” the antibodies produced by the new coronavirus infected person.

Since the kit is not interfered with by “bacteria”, it will not affect the results of antigen detection.

For some people who think that “bacteria” sampling swabs will affect human health, experts say that this may be due to a lack of understanding of “sterile” products.

Sterile

The single-use Specimen collection swab can currently be applied for registration as a second-class medical device, and can also be registered as a first-class medical device (the third-class is the highest level) in the regulatory department.

If it is a Class II medical device, it must meet the sterility requirements when it leaves the factory. While a Class I medical device has no relevant requirements and can be listed in the state of “non-sterile” and “unsterilized”.

Experts said that “sterility” refers to the state of no viable microorganisms. All medical devices must meet certain hygienic requirements, such as strict control of the number of microorganisms before they can be qualified for the market.

Flocked Sterile Swabs

Flocked swabs are mainly used for oral and nasopharyngeal sampling, cervicovaginal sampling, and laboratory testing.

Sterile Flocked Nasopharyngeal Swab is a 100% nylon flocked swab that provides exceptional absorption quality with a flexible handle engineered to reach remote areas of the nasopharynx for specimen collection.

According to different uses, it can also include nasopharyngeal swabs, throat swabs, oral swabs, DNA swabs, and cervical swabs.

It is similar to the above classification, but it is slightly different.

For laboratory testing centres and hospitals.

What are the advantages of flocked Sterile swabs?

Using nylon fibre flocking technology. The front end of the swab has nylon staple fibres fixed vertically. By making the entire collection area of ​​the swab free of absorbent holes. The sample does not scatter and become trapped in the fibres, facilitating faster and more efficient elution.

This makes flocked swabs ideal for PCR work, as flocked swabs are biocompatible and ideal for PCR work.

Nasal swabs reused at an Indonesian airport? What are the dangers of reusing nasal swabs? 

Since the epidemic, the term nasal swab testing has entered our lives. Basically, you will be asked to do a nucleic acid test when you are on a business trip or travelling. After the test is completed, the sterile flocked swab will be processed for medical waste. However, news broke out recently that refreshed the three views, and netizens called out “there is no bottom line”!

According to reports, employees of a medical company in Indonesia were found to be repeatedly using sterile nasal swabs when testing airport passengers. At present, more than 9,000 passengers are expected to be affected.

After investigation, the Indonesian police found that the employees involved first performed Nasopharyngeal Swabs tests on passengers with sterile nasal swabs every day, then cleaned the used sterile swabs with alcohol, and then packaged them for use by the next batch of passengers. . This behaviour is outrageous.

What are the dangers of reusing nasopharyngeal swabs?

The nose is a barometer of human health. When there are lesions in the body, the colour of the snot changes to yellow or green. Nasopharyngeal swabs are a test sampling method to assess the presence of respiratory viral or bacterial infections by collecting samples from the surface of the respiratory mucosa.

As a rule, nasal swabs cannot be reused. If the nasal swab is reused, the consequences will be disastrous.

If the nasal swab is reused, it will increase the risk of virus infection. Previously, a British research team found that two kinds of cells in the nose may be the other infection sites of the new coronavirus. A clinical study found that the viral load of nasal flocked swabs The amount is significantly higher than that of throat swabs. If nasal swabs are reused, it is likely to cause cross-infection and expand the scope of infection.

On the other hand, it may lead to inaccurate test results, false positives or false negatives. It may cause psychological panic and unnecessary treatment to the subjects, and false negatives may mean that the subjects cannot find out that they have been infected in time, miss the best treatment time, and even cause more people to be infected.

Why are the sample collection swabs for nucleic acid testing all put together?

This kind of multi-person mixed inspection can improve efficiency and reduce costs.

"<yoastmark

Mixed sampling testing refers to mixing samples from multiple people (generally no more than 10 people) into the same test tube for testing, improving testing efficiency and reducing testing costs, but the waiting time for centralized sampling may be slightly longer. According to the voluntary principle, the nucleic acid test of all employees can be tested by mixed sampling technology. The laboratory testing time for mixed sample and single-tube testing is the same, which does not affect the time for issuing the testing report.

The so-called five-in-one and ten-in-one mixed sampling detection technology are to put 5 or 10 individual swabs into a collection tube. When the test result is negative, the mixed sample is negative, and the mixed sample is 5 people. or 10 people are safe;

If there is a positive result, the relevant department will be immediately notified to temporarily isolate the 5 or 10 subjects in the mixed tube, take a single tube swab again for the review, and then determine which of the 5 or 10 people is positive.

What should I pay attention to when doing a nucleic acid test (PCR test)?

Today,  many people who travel to and from high-risk areas of the epidemic require nucleic acid testing.

So, what should we pay attention to when doing nucleic acid testing (PCR SWAB TEST)?

Before the nucleic acid test: do not eat within 2 hours, do not smoke or drink within 30 minutes, carry a valid ID card, wear a mask correctly, and inform the testing personnel of past medical history or related matters.

When doing nucleic acid testing: Keep a distance of more than 1 meter when queuing, tilt your head slightly, relax, take a deep breath, and have symptoms such as dry cough or sneezing, use a tissue or cover with your arm.

After the nucleic acid test: leave the collection site immediately, and wipe your hands with hand sanitiser or alcohol.

In fact, whether it is a nasopharyngeal swab or a throat swab, it is an effective virus detection method. Although there will be slight discomfort during the test, it will soon return to normal and will not affect your health. Therefore, if necessary, we must actively cooperate with nucleic acid testing, which is responsible for ourselves and others.

Nucleic acid detection: For virus detection method.

It uses a collection flocked swab to collect a sample from the throat or nose of the tester and then conducts the test to obtain the final result.

Some people found that the flocked swabs for nucleic acid testing will be placed in a bottle(VTM Tube).

This is a mixed test, and most of them occur during nucleic acid testing of all staff, which will not affect the detection effect.

Will the swabs for nucleic acid testing be reused?

Prohibition reused.

In addition to sampling, reagents and other factors, the subject’s own reasons may also lead to “false negatives”.

Not to eat for two hours before the nucleic acid test, not to drink water for the first 30 minutes. And not to smoke, drink water or chew gum to reduce behaviours that may interfere with the test results.

There are other influencing factors before sampling and testing,

1. Please do not take antibiotics a few days before the nasal swab.

2. Do not use disinfectant mouthwash or smear on the affected area a few hours before the nasal swab.

3. Do not eat, smoke, or drink for a few hours before the nasal swab.

They are packed with a transport medium (inactivated type, preserved type) for the release and preservation of samples to prevent leakage.

The sampling tube has built-in magnetic beads, which are convenient for elution and facilitate the release of more viruses into the virus transport medium.

Before the higher positive rate of PCR detection, the storage solution in the virus sampling tube was Hank’s solution.

Now, the virus sampling tube preservation solution has been upgraded to CellMedical virus preservation solution.

(that is, UTM, recommended by the World Health Organization and the National Influenza Center of China.)

Based on hank’s solution, BSA, HEPES, amino acids, glycerin and other ingredients. A high PCR test is positive.

Virus preservation solution includes non-inactivated virus transport medium and inactivated virus

In the non-inactivated COVID-19 sampling swab set, the components of the virus preservation solution usually include nutrients (such as salts, proteins, glucose), bacteriostatic agents, buffers, phenol red indicator, etc. required for the survival of the virus.

This virus preservation solution can maintain the activity of the virus to the greatest extent.

Not only for virus detection but also for virus culture and isolation.

In the inactivated new coronavirus sampling swab kit, the components of the virus preservation solution usually include buffers, virus lysing agents (usually guanidines), surfactants, etc.

This preservation solution can directly lyse the virus to release nucleic acid, which is convenient for subsequent nucleic acid detection.

Nasal Swab Test

The person who did a few nasal swabs tells you how to do it without pain.








I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab.


I see a lot of people on the Internet saying that the nasal swab is very painful, sour and straight to the sky, this is because your posture is not correct! !!




How Accurate Is The Nasal Swab
Nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.




Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab.


Their purpose is to let the flocked swab sample from the inner wall of the throat.


Nasal swabs are not meant to poke your heavenly lid!


Nasopharyngeal culture


A nasopharyngeal culture is a test that examines a sample of secretions from the uppermost part of the throat, behind the nose, to detect organisms that may cause disease.

Therefore, you should tilt your head as far back as possible to allow the cotton swab to go in horizontally.


That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds.


But if you keep your head upright, then the flocked swab can only be poked from bottom to top, which will definitely pierce the upper part of the nasal cavity.


That position is very sensitive, and it will hurt very much when pierced.


And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.


One sentence summary: Tilt your head back and let the flocked swab go in and out horizontally all the way.




 Why you should take the swab test.


This test identifies viruses and bacteria that cause upper respiratory symptoms. 


These include: 


Bordetella pertussis, the bacterium that causes whooping cough Meningococcus meningitidis. 


The bacterium that causes meningococcal meningitis is Staphylococcus aureus, the bacterium that causes staph infections Methicillin-resistant Staphylococcus aureus virus infection. 


For example, influenza or respiratory syncytial virus cultures can be used to help determine which antibiotic is appropriate to treat infections caused by bacteria. 


Normal Results The presence of common organisms in the nasopharynx is normal.


 What an abnormal result means The presence of any disease-causing viruses, bacteria or fungi means that these organisms may be causing your infection. 


Sometimes, organisms like Staphylococcus aureus can exist without causing disease. 


The test can help identify resistant strains of the organism (methicillin-resistant Staphylococcus aureus, or MRSA) so that people can be quarantined if necessary.


 Risks There are no risks to this test
