Dear Mr. Riad!

According to the latest available knowledge, no - insects do not contribute to the transmission of COVID-19: YET. In the future as this virus mutates approximately every second week and as it spreads out dynamically around the world, the situation might change.

I think that insects, when coming into contact with a body contaminated with the virus, may carry it on some parts of its body, and when it is transferred to the body of a healthy person, the virus may pass on the face or mouth of the healthy person and move to the respiratory system. Is that correct?

Yes, it is possible.

Possible. Please take a look at these articles: Article A Brief Review on the Possible Role of Houseflies and Cockro...

Yours sincerely, Bulcsu Szekely

We have considered the possibility that mosquitoes might become a vector transferring Ranavirus to humans, so with COVID-19 we do face the same risk as the mosquito body would provide both transport and a safe environment for the virus while in transit.

I t must to model.

Md Rabiul Alam

Very important articles.

Puneet Kumar We need to review articles from Md Rabiul Alam

Bulcsu Szekely thank you Dr. good idea.

Manizhe Zakeri I thought about this, but we do not have the financial or laboratory capabilities in Egypt to deal directly with the virus.

Thanks

No, I think virus is transmitted through touch and fluids of the body and the respiration.

COVID-19 virus does not need any vector for its transmission in the first place. However if any fly or insect sits on droplet containing the virus then there lies a chance that any micro droplet containing the virus may get transferred to another surface or exposed skin of human being which may lead to indirect transmission. But indirect transmission can occur through various routes. So best principle is to maintain proper health hygiene.

Dear Dr. Saber uptil now there is no evidence to prove that Covid 19 can transmit by flies or mosquitoes but The transmission by non blood sucking flies may be occur by mechanical route but msosquitoes can not transmit the virus where its transmission route through respiratory passage

According to a statement from the World Health Organization, dated April 10, "The new coronavirus CANNOT be transmitted through mosquito bites"

Hello Doctor

I do not think so, because this virus is transmitted through the spray of an infected person and it is known that the mosquito insect is a nature fed to the blood of the host and is not transmitted by this means .

No since the mode of transmission is through droplets (aerosol) from infected individual through coughing or sneezing

The question must be asked in another way. If an insect gets dirty with an aerosol droplet from an infected human, does it transfer a viral load capable of infecting another man? One of the principles of virology says that an adequate load is needed to infect (along with virulence and human predisposition).

According to the WHO it is not possible.

I don’t think so, because this virus is transmitted through the spray of an infected person, and it is known that a mosquito insect is a nature that feeds on the host’s blood and is not transmitted in this way. According to WHO, this is not possible.

Dear Mr. Sabar A. Raid

Insect have requirement as a vector borne-diseases, one has suitable receptor with ligan that recognition between insect and virus. Therefore, insect have to provide a receptor such as ACE2 to transmition COVID-19, untill now flies or mosquitoes have not been ACE2 to supporting zoonotic virus that COVID-19 needed

What are you surprised at? SARS-CoV-2 is a human parasite, insects are evolutionarily very distant. Some insects such as the fly can only get dirty with the virus, because in order to eat they are forced to liquefy (hydrolyze) food and its particulate with enzymes from the buccal system, and there is always the problem of the viral load. To develop a host-parasite functional affinity, a long co-evolution is needed. The two partners must know each other deeply for a very long time to establish functional relationships.

SARS-CoV-2 knows very well the structure of ACE2 in order to implement an effective binding, uses very specific human proteases to open its "armor" (envelope + capsid), uses some of its proteins to interact with the host metabolism and, to do this, it must interact through effective binding with human proteins. Nothing is random. The virus has molecular knowledge of the host in its genome.

The only way to shorten this process is to encounter a different virus in the same infected cell that transmits molecular information to it, by transfection.

Mohamed R. Alkotby we need some research, Thanks

Dhrubalal Pandey but we need some research about mechanical transmission.

Mousumi Basu I think that.

Mostafa Ibrahim Hassan Thanks, Prof, Dr. Mustafa, I think that.

José Francisco Carrasco but I think transmitted by insect mechanical transmission.

regards,

Nebras Sahi but, maybe some flies transmit the virus mechanically.

best regards

Mzelifa Daud or by the virus from the surfaces, hands, face, and others.

best regards,

Giovanni Colonna good information, thanks.

Leonardo Mataruna but we need some research about the mechanical transmission by flies.

best regards,

Pushkin Sergey Viktorovich What about house flies and mechanical transmission of the virus.

thanks,

Munawir Sazali

What about house flies and mechanical transmission of the virus.

thanks,

Giovanni Colonna

What about the mechanical transmission of virus by flies.

thanks,

Respected Saber A. Riad. Fly transmission has not been studied by me. Through objects, the virus is transmitted. If you do not treat the surface, the virus persists for up to 3 days. Regards, Pushkin Sergey Viktorovich

Best regards Dr. Pushkin Sergey Viktorovich and thanks for sharing me.

we a lot of extensive research to approve or disapprove the transmission of COVID19 by insects. but what I think, as the virus infects the respiratory system of human beings which is totally different than insects respiratory system, insect transmission of the virus will be very difficult

Youssef Ezzeldin Abdallah

No, what I mean is that parts of the fly's body are contaminated with the virus from the infected person and during its transmission from one person to another it leaves the virus on the body of the healthy person.

best regards

Youssef Ezzeldin Abdallah

Thanks for sharing.

I agree with your opinion, dear Prof. Dr. Mostafa Ibrahim Hassan

I think this is critical point to answer it via researches, and there is no evidence to disprove or prove it.

I agree with your opinion Dr. Ibrahim Hussein

if mutation happends to the COVID virus there may be chance for the insect transmissioin

Respected Saber A. Riad there's no evidence of insects transmission but it may be possible if sudden mutation occurs depending upon the climate conditions.

If flies and mosquitoes transmit the COVID-19 virus as a mechanical transmission the whole world will be affected. but this time about 699 corer people are well when about 1 corer people are affected. though it is a big number of people are affected, maybe flies and mosquitoes do not transmit the COVID-19 virus.

It is my personal belief that the virus can be transmitted through animals, as well as insects.

To date, there is no evidence or information to suggest that the COVID-19 virus is transmitted through domestic flies. The virus that causes COVID-19 is mainly spread through the generated mist when the infected person coughs, sneezes or talks.

Dear Dr. saber

Concerning the transmission of COVID-19 by sucking biting insects such as mosquitoes or other insects in the context of phoresia and the spread of the disease, according to my information no research has been carried out in this direction the goal currently is to seek the means which it is necessary to reduce the effects, perhaps in the future the scientific community will realize that this component is very important

good continuation

I agree with your opinion Dr. Linda Cheriak

regards,

Fawaz Yaseen Abdullah I agree with you.

Thanks,

Md SUMSUDDIN Sumon I believe that there are many people infected with the virus who passed them despite the house isolation for long periods before this infection.

Best regards,,

Neeraj Kumar Tripathi

I agree with you.

Thanks,

Azharuddin kappil Kappil we talk about mechanical transmission it is far from the genetic structure of bacteria or viruses in general.

Best regards,

Whether flies and mosquitoes can transmit covid is an issue that draws attention away from the real problem. The considerable attention on covid and the measures in place for sanitization has stolen money from the procedures that are implemented against insects in general. The result is that environmental remediation has not been done in many countries. This will cause a significant increase in diseases transmitted by mosquitoes and ticks, regardless of the virus. Therefore, whether to fight flies, mosquitoes, ticks and other insects, the answer is YES, regardless of the disease, otherwise we will find ourselves fighting many other serious diseases that have not been contained with the appropriate actions.

Giovanni Colonna

I agree with you.

Thanks,

Best regards,

No, however this issue may be investigated.

Kuldeep Dhama

Of course, we need such studies.

Best regards,

its great obvious that the respiratory truce or respiratory passages are the main targets for multiplying and reproductive the COVID-19 due its affinity to these tissues so , if in chance to trans-meted to human body by any way to any other tissues except respiratory truce still not effective to caused infection.

Majid J Al-saadi

Of course,

Thanks.

https://www.researchgate.net/post/Covid_is_making_the_technology_go_viral

Dear Colleagues, I suggest consistently arguing. Coronavirus at certain stages circulates in the blood and accumulates in human and animal monocytes. If a mosquito or other blood-sucking insect receives blood from a coronavirus carrier, will the coronavirus enter the mosquito system? So it gets. If this blood-sucking insect with coronaviruses inside comes in contact with a healthy person or animal, is there a chance that the coronavirus will get to the “former” healthy person ?.

I am sure that the reader himself will draw a conclusion from these arguments.

Dear Mr. Riad,

There is still no evidence to prove mosquitoes or flies can act as mechanical transmitters of COVID-19. I agree with some answers as its a respiratory illness , thus the chances of mosquitoes acting as mechanical transmitters are low. But a proper study should be carried out to determine for sure.

Thanks Sirvan Abbasbeigi .

My best wishes.

Thank, Manu Vasudevan Unni good effort.

Vladimir A. Kulchitsky ... Through biological transmission, it will not happen, but blood-sucking insects may transmit the virus mechanically.

Best regards,

I agree with your opinion Dr. Sachini Fernando

Best regards,

To the best of my knowledge, there is no evidence yet supporting the possible role of insect in SARS-CoV2 transmission. However, this remains an interesting issue to investigate.

May be!!!

Dear Dr. Saber

I think that, there is no evidence that they can or cannot mechanically carry or transmit the virus till today, means it could be a potential carriers, and we all should be aware of them until this critical issue figured out.

All the best.

Dear all!

Remember - Never Say - Never!

I guess it is not transmitted by insects

Fatema Tabak thanks,

Best wishes

I agree with your opinion Dr. Firzan Nainu

best regards,

Good idea Dr. Ahmed Hasaballah thanks for sharing and best wishes.

Vladimir A. Kulchitsky I couldn't understand what you mean???

Yousif Yaqoob Yousif may be.

best regards,

This hypothesis isnt reasonable for the following reasons

1. Viruses transmitted by mosquitoe have the capability to invade epithelial cells of the carrying flies and the multiply their selves to be ready for human cells infection. So the intermediate host which is the mosquiteo is necessary for that viruses performance.

2. Bioinformatic analysis presented animal hosts that could be a source for coronaviruses, there is no database showed any possible interaction between viral spikes and mosquiteo proteins which make this hypothesis lack of genetic bases

3. Social distance and mask wearing significantly clearly eliminated viral spread and infections. If there is a possible for mosquito role it will be niticed particularly in tropical countries

Sorry for some writing mistake because of mobile using. By the way I also want to add apoint that recent reports revealed that there is no evidence for confirmed infection by touching of surface. Hence transmission of virus by the legs or wings or other parts of insects body isnt reasonable because insects are not the main reservoir. Otherwise books, clothes, chairs, desks, everything will be in the circle of risks

Murad Alahdal I agree with you. but what about flies mechanical transmission of the virus?

Best regards.

Murad Alahdal

yes, I saw another comment from you now and agree with your opinion.

Thanks

Mohammad Parvaiz Qamar Farshori

Thanks, I agree with your opinion.

Best regards,

I think this virus does not require a vector (mechanical or biological) because its transmission is direct by droplet or contact with contaminated surfaces.

If we suppose that this virus needs a vector how does it transmitted to human (respiratory tract) by these insects.

As you know respiratory tract pathogens are transmitted directly by inhalation.

Dear Dr. Riad,

Thank you very much for asking a valuable question. Actually, there is no clinical evidence that can prove the flies or the insects are responsible for Covid-19 transmission, till now. However, if there is any kind mutation or genetic encoding happens that may lead to that stage of transmission, as for now, the answer is negative. Also, it isn't proven that pets can transmit those viruses to human bodies.

Yes, I Agree That There's No Scientific Prove That Flies & Mosquitoes Mechanically Transmit COVID-19

There is no evidence of mechanical transmission of COVID-19 by any insect

Although no research in this regard is available, the probability is not 0. We have to realize that what was seen impossible for SARS-Cov-2 yesterday may become reality tomorrow.

Dr Sundar Elayaperumal, specialist microbiologist at Burjeel Hospital, Abu Dhabi, said there is no evidence to suggest that the virus that causes COVID-19, can be transmitted through blood directly or through insect bites. “This is a myth and so far not scientific. However, there is a chance that the common housefly might be a mechanical vector for the spread of the infection as the fly can sit on a contaminated surface and transmit it to another surface.

https://gulfnews.com/uae/health/can-covid-19-spread-through-insect-bites-houseflies-1.70869982

I think until now there is no evidence that Covid-19 virus could transmitted by flies, however, this must be confirmed by experiments.

Hi all participants and have a nice week. In the following RG open question I attempt to search causes of the Lombardia hyper cluster of COVID19,

https://www.researchgate.net/post/The_novel_Coronavirus_in_N_Italy_Lombardia_COVID19_2019nCoV_SARSCoV2_shows_a_fatality_rate_compatible_with_SARS-MERS_Why

a very worst case.

In order to obtain data, there are extensive bibliographical lists about

--oral-fecal contagion

--chemicals vs. SARS-CoV/2

--receptor ecosystem

--animal reservoirs

--Guillain-Barrè syndrome

-- co-infection (other local CoV)

-- comparative data vs. others world hyper clusters

I hope this is an interesting point to obtain data for this dramatic situation in N. Italy (and Central Europe), in order to prevent similar evolution in the next future.

-sv-

Technically, it is possible for flies: by their legs they can carry enough viral load to infect people. This can be by sitting on infected surface, then moving to another surface, which humans/animals touch or eat.

Danish Kadir thanks, dear.
