Scientists have claimed the coronavirus can enter the body through the eyes after finding they contain a protein used by the infection to bind to cells, Daily Mail of UK has reported.
The coronavirus – scientifically called SARS-CoV-2 – latches onto ACE-2 receptors, known as the ‘gateway’ into cells inside body.
These receptors are found in the respiratory tract and the lungs, which is where the virus first infiltrates cells, as well as other organs.
A team led by Johns Hopkins University School of Medicine in the United States have now found the eyes produce ACE-2, making them a target for the virus.
It means if droplets from an infected person’s sneeze or cough were to land on the surface of the eye, the virus could begin infiltrating cells there.
It may explain why some patients have suffered conjunctivitis – an inflammation of the eye which causes it to become red and infected.
Not only could the virus enter the body through the eyes, but tears may serve as a spread of infection, scientists said.
The team was led by Lingli Zhou of the Department of Ophthalmology, Johns Hopkins University School of Medicine, Baltimore.
They analysed 10 human post-mortem eyes from people who did not die of COVID-19 for the expression of ACE2 (angiotensin-converting enzyme 2).
ACE-2 is understood to be the entry point for the virus. Its spiky surface binds to the receptors and, from there, infects the cell and replicates.

It’s suggested that someone with more ACE-2 receptors may be more susceptible to a large viral load – first infectious dose of a virus – entering their bloodstream.
The team also looked for TMPRSS2, an enzyme that helps viral entry following binding of the viral spike protein to ACE2.
ACE2 and TMPRSS2 must both be present in the same cell for the virus to effectively replicate.
All eye specimens expressed ACE-2 in the tissue that lines the inside of the eyelids, called conjunctiva, the clear outer layer of the eye, called the cornea, and the limbus, which is the border between the cornea and the white of the eye.
TMPRSS2 was also expressed, according to the pre-print paper on MedRxiv yet to be reviewed by other scientists.
Dr Zhou and colleagues wrote: “Together, these results indicate that ocular surface cells including conjunctiva are susceptible to infection by SARS-CoV-2 and could therefore serve as a portal of entry as well as a reservoir for person-to-person transmission of this virus.”
The research was triggered by ‘extensive speculation’ that eye surfaces are a possible site of virus entry.
Although the virus primarily spreads through droplets of saliva or discharge from the nose from an infected person lands on the insides of another person’s nose or mouth, scientists have said it’s entirely possible it could enter through the eye.
Reports have suggested that COVID-19 may cause conjunctivitis, which was a symptom in around 30 per cent of patients in one study.
The researchers explained this could be as a result of the virus travelling from the respiratory tract to the eyes – a secondary complication often linked with a virus.
But it could also be a direct result of the virus attacking the eye cells in the first place by binding to ACE-2 receptors.
Dr Zhou noted that viral particles can be found in tears that ‘could result in transmission to other individuals’.
“Infection of ocular surface cells could lead to the eye as being an important carrier, with ocular virus shedding constituting a significant mechanism for infection of other individuals,” they wrote.
“This highlights the importance of safety practices including face masks and ocular contact precautions in preventing the spread of COVID-19 disease.”
It was not specified if the general population would benefit at all from eye protection, or if the academics meant health workers specifically.
Medics on the pandemic frontline are supposed to wear goggles or face visors in order to protect their eyes.
Focus On Gumi, Shekau Before Chasing Me, Igboho Tells FG

had filed a motion for bail of his client and pleaded for the remand of
the defendant in the custody of the EFCC pending the determination of his bail application on the grounds that “the defendant has been on administrative bail for almost five years and he has an underlining sickness”.
However, the prosecution counsel objected to the application. “As he
rightly submitted, we received the application but we shall vehemently
be opposing the application; we said vehemently so that the court will
know that we have a strong opposition. Moreover, our facility is
overstretched because of the issue of the Covid-19 Pandemic, the little
we have we are trying to manage them. The proper place of detention or
custody is the Correctional Service which the government has done its
best in providing”, Menji told the court.
However, Justice Oriji adjourned the matter till March 4, 2021 for
hearing on the bail application and remanded defendant in EFCC custody.
Niger Delta Militants Threaten To Attack Lagos, Abuja
Niger Delta militants under the aegis of Supreme Egbesu Liberation Fighters have threatened to destroy infrastructure in Lagos State and Abuja .
In a video posted on Tuesday by AIT , members of the group were seen wearing masks and putting on a military uniform .
One of them , who read a statement on behalf of the group , lamented poor implementation of the amnesty programme in the region, saying , “ there are no schools , no potable water , no light , no hospital and access roads for our people to enjoy till date” .
He said , “ Over the years, the Niger Delta people have made frantic efforts to create an enabling environment but to our great dismay, the Nigerian government over the years has decided to handle the issues of the Niger Delta with kid gloves .
“ They have betrayed the struggle and have left the people to their fate ,” a member of the group read from a statement .
“ Rather, what is visible is the presence of military gunboat and the numerous military personnel dispersed to the Niger Delta who are killing, raping , and maiming the innocent people of the region.
“ Look at the security surveillance contract taking place in our region through the federal government these agencies in place have decided to shortchange our people . Now in our territorial waters , it is an Israeli company that is providing waterway security which we have competent hands with expert knowledge to manage.
“ Don ’t worry, because we are coming to destroy all your infrastructure in Abuja and Lagos . As a group committed to giving total liberation to our people , we will destroy the oil facilities both onshore and offshore in no distant time , we will be seen to be crippling the Nigerian economy. ”
