SARS-Cov-2 can not penetrate through Cornea of Eyes, says study
- The researchers at Washington University School of Medicine in St. Louis in their recent study have reported that the novel coronavirus can not penetrate through the eye’s cornea.
- The findings were published in the journal Cell Reports.
- The study further says that the herpes simplex virus can infect the cornea and spread to other parts of the body in patients with weak immune systems.
- Researchers noted that, though Zika virus has been found in tears and corneal tissue. But, COVID-19 causing a virus called SARS-CoV-2 can not replicate in the human cornea.
- However researchers have not yet determined whether other tissues around the cornea, like tear ducts and the conjunctiva, are vulnerable to the virus or not.
- Corona Viruses are a group of RNA viruses. It causes diseases in mammals and birds. They cause respiratory tract infections in humans and birds.
- Mild illnesses in humans cause the common cold while lethal varieties can cause SARS, MERS, and COVID-19.
- In cows and pigs they are responsible for causing diarrhea. There are no vaccines or antiviral drugs available to prevent or treat human coronavirus infections.
- Coronaviruses subfamily- Orthocoronavirinae:
- Corona belongs to the subfamily- Orthocoronavirinae in the family of Coronaviridae. They are enveloped viruses that contain a positive-sense single-stranded RNA genome.
- The earliest reports of a coronavirus infection dates back to the 1920s. Then, an acute respiratory infection of domesticated chickens was reported in North America. However, Human coronaviruses were discovered in the 1960s.
- Coronaviruses primarily target the epithelial cells.
- These viruses are transmitted from one host to another host either by an aerosol, fomite, or fecal-oral route.
- Human coronaviruses infect the cells of the respiratory tract while animal coronaviruses infect the cells of the digestive tract.
- For instance, SARS coronavirus transmit through aerosol and infect the human cells of the lungs by binding to the angiotensin-converting enzyme 2 (ACE2) receptor.
More children to get fortified rice
- The government is planning to distribute fortified rice to children in anganwadis and government schools.
- The rice would be infused (fortified) with iron, folic acid and vitamin B-12.
- The government is planning to distribute fortified rice through the Integrated Child Development Services and Mid-Day Meal schemes across the country.
- An existing pilot scheme to distribute fortified rice through the Public Distribution System in 15 districts has only been implemented in five districts so far, despite the lapse in more than half the project duration.
- The Centrally sponsored pilot scheme was approved in February 2019.
- Only Andhra Pradesh, Gujarat, Maharashtra, Tamil Nadu and Chhattisgarh have started distribution of fortified rice in their identified pilot districts.
- The food ministry said that it would lay special focus on 112 aspirational districts.
- The Food Corporation of India has been asked to come up with a comprehensive plan to scale up the annual supply of fortified rice from the current 15,000 tonnes to at least 1.3 lakh tonnes.
About Fortification of Rice:
- Fortification is the practice of deliberately increasing the content of an essential micronutrient, i.e. vitamins and minerals (including trace elements) in food, so as to improve the nutritional quality of the food supply.
- Generally, fortified rice contains Vitamin A, Vitamin B1, Vitamin B12, Folic Acid, Iron and Zinc.
- Fortifying rice involves grinding broken rice into powder, mixing it with nutrients, and then shaping it into rice-like kernels using an extrusion process.
- These fortified kernels are then mixed with normal rice in a 1:100 ratio, and distributed for consumption.
- Currently, there are only 15,000 tonnes of these kernels available per year in India.
