공인ip It’s been more than a year since Covid-19 hit India. Covid-19 is a disease caused by novel coronavirus, SARS-CoV-2. This virus causes contagious respiratory illnesses with potentially life-threatening complications. The best characterized symptoms of infectioninclude loss of taste and smell, cough, fever,difficulty in breathingand tiredness among others. Individuals with these are advised to get tested for coronavirus infection, and recommended appropriate quarantine and safety measures to curb immediate spread.But there are also people who carry the virus, and do not show any symptoms. They are one of the most difficult to trace. They are also considered one of the largest reasons for the spread of the infection. Anewly emerged infection doesn’t always have established treatment regimes. Covid-19 is no exception. So, the primary strategy had been to limit the spread 공인ip of coronavirus. India has tried nationwide lockdown first, followed by statewide and even more regional lockdowns. While lockdowns might contain the spread of virus, they have added a huge emotional and financial burden onto people. And we have now seen that as soon as the lockdowns are lifted, people’s interactions have been enough for the virus to spread. This has put an enormous toll on India’s healthcare system.Lockdowns are not sustainable over long periods of time, and we need to adopt a new living that still keeps us safe from the coronavirus infection and Covid-19. Let’s understand the elements of this new living, one at a time.Wear masks – Cover your mouth and noseMasks, when worn to cover our mouths and noses, help prevent the spread of Covid-19. When we 공인ip sneeze or even speak, we spit out aerosols into air from our mouths and noses. People around us inhale these aerosols. If we are infected with coronavirus, the aerosols from our sneeze can also infect other people around us. A mask simply blocks this spread. The mask wearer spreads lesser aerosols around them as well as protects themselves from aerosols to some extent. While there are several types of masks available, nearly each one of them work by reducing the spread of aerosols. This is alsowhy we find it slightly difficult to breathe while wearing them.Masks are primarily divided into two types – medical and non-medical.Medical masks are designed generally with filters in place to prevent even small droplets in the air fromleaving and entering. The N95 particulate respirators and 공인ip the 3 ply/surgical masks are examples of this. N95 masks filter out 95% particles from the air breathed through it whereas surgical masks remove 70% particles. Non-medical masks include those made of cotton or three mesh-layered masks designed to protect us from spreading large aerosol droplets. Source:https://www.bizjournals.com/charlotte/news/2020/09/01/a-guide-to-the-different-types-of-face-masks-and-h.html Avoiding crowds - Maintain distance of 2 arms lengthWhile masks work by preventing most of the aerosols from going out or coming at you, the effectiveness is also based on distance the aerosols travel. Let’s take an example of two scenarios concerning a gathering of you with two other people. In the first instance, you are less than one arm distance. If one of them sneezes, most of the aerosols will be contained by their mask (provided they are wearing it right). But a few 공인ip will still go through. Now consider two arms’ length or six feet from each other. Now if anybody sneezes, because of the sheer distance separating them, many more aerosols that pass through will eventually fall down to any surface before they find another person as compared to the former situation.To prevent the spread of coronavirus, avoiding crowds is a must. Source:CDC Hand hygieneLet’s consider this scenario. A coronavirus positive individual, possibly unaware of their infection status, sneezes in a store. The aerosols containing the virus are littered across different surfaces of the room around them. It is known that the virus can last for upto a few hours on most surfaces. Now imagine yourself in that room, unaware of who has occupied the room or the events that may have occurred earlier. 공인ip You can touch the contaminated surfaces and then your face or nose and pass on the virus into your body. An alternate scenario is where you frequently wash your hands or rub them with alcohol-based sanitizer. These help to break the virus particles and keep you safe from the virus you might have picked from surfaces especially in public spaces. It is also important to clean surfaces in common public areas.To prevent the spread of coronavirus, avoiding crowds is a must.Vaccination – Follow recommended guidelinesVaccines train our immune system to fight a microbial infection. There are three vaccines against Covid-19 available in Indiaand others are on the way. These are currently meant for individuals aged 18 years and above. All of them contain whole or parts of inactivated coronavirus that 공인ip trains our immune system to be ready in case of a real infection. Most people get mild or no side-effects upon taking the vaccine. They are to be taken in doses as prescribed by the vaccine companies. The vaccines don’t prevent infection. However, those vaccinated have more manageable symptoms and have a lower need for hospitalization.For further reading on the vaccines available in India, refer the following fact sheetsCovishield - https://www.seruminstitute.com/product_covishield.phpCovaxin - https://www.bharatbiotech.com/images/covaxin/covaxin-fact-sheet.pdfSputnik V - https://sputnikvaccine.com/about-vaccine/It is also important to acknowledge that vaccination drive will work against Covid-19 only when most of us take the vaccine. In absence of that, newer variants of the coronavirus can arise. These newer variants can undermine the immune training done with vaccines made from older variants.Individuals with symptoms similar to that of Covid-19 infection 공인ip are advised to consult their doctor prior to vaccination. Source:https://www.cowin.gov.in/home In summary, Source:CDC In the last one year of Covid-19, a lot has changed about our daily lives. We wear a piece of cloth on our faces that we aren’t used to. In a country like India with a rich cultural heritage, festivals hold an important place in our lives. Physical distancing norms don’t allow them the way we are used to. We might fear vaccines or needlesin general. But these are the best ways right now for all of us to follow and fight the virus.Author:   R Abishek Bharadhwaj   PhD Student   CSIR-Centre for Cellular and Molecular Biology   Edited by:   Dr Somdatta Karak   Science Communication and Public Outreach Officer   CSIR-Centre for Cellular and Molecular Biology     For more details on the vaccination in India, refer  https://www.mohfw.gov.in/covid_vaccination/vaccination/faqs.html
