The nervous system is frequently impacted by COVID-19 directly or indirectly. Scientists analyzed and explained how SARS-CoV-2 infects brain cells called pericytes.
Test your Knowledge on Coronavirus (COVID-19)
Coronavirus is a large positive-strand RNA virus that is surrounded by a protein envelope. The virus obtains its name from the S protein spikes on its surface, which resemble a crown. The overall pattern of increasing coronavirus cases is shown to spike up with the “second wave” of COVID-19.
With spiking effects of the second wave of coronavirus, the best way to keep it at bay is to follow COVID-appropriate safety practices like wearing a mask, regularly cleaning your hands, and coughing into a bent elbow or tissue along with physical distancing (6 feet about 2 arm's length), that may help evade the severity of COVID-19 infection.

‘SARS-CoV-2 can infect pericytes and multiply within them. From there, the viruses disseminate among astrocytes and impact the neuronal system.’
"The prospect of COVID19-induced brain damage has become a primary concern in cases of ’long COVID,’ but human neurons in culture are not susceptible to infection. Prior publications suggest that the cells that make the spinal fluid could become infected with SARS-CoV-2, but other routes of entry seemed likely," said senior author Joseph Gleeson. The Neurovascular unit is engaged in regulating cerebral blood flow and blood-brain barrier function. It consists of many specialized cells, including pericytes, astrocytes, and neurons.
Coronavirus
Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

Pericytes that wrap around blood vessels of the brain contain the SARS-CoV2 receptor. Taking this in mind, researchers from the University of California, San Diego introduced these cells into 3D-brain cell cultures and created a complex model of the neurovascular unit of the human brain.

Do Pets Catch Covid-19 from Their Owners?
Pet dogs and cats do catch Covid-19 from their owners. Covid-19 rates are higher in pets that have been in contact with Covid-19 people than in pets without such contact.

Parenting Guide: Can Third Wave Affect Children?
Covid-19 third wave: There is no evidence that the third wave will affect only children. However, parents should prepare for the worst until Covid-19 pandemic is over. So, the best way to protect your child is to follow the preventive measures.

Although the research revealed potential invasion of SARS-CoV-2 into the human CNS, other evidence showed that most neural cells have little to no capacity for SARS-CoV-2 infection. Yet, the research provides a robust model to study the effects of novel coronavirus on the neuronal network.
