COVID-19 is a disease caused by a new coronavirus called SARS-CoV-2. It was first found on 31 December 2019, as a cluster of viral pneumonia in Wuhan, People’s Republic of China. Back then has been spreading all over the world causing the death of many peoples. Due to the spread of Covid- 19 all over the world and its adaptation or mutation with the environment various forms or mutants are formed.
Symptoms of COVID-19
According to WHO,
The most common symptoms of COVID-19 are:
- Dry cough
Other symptoms that are less common and may affect some patients include:
- Loss of taste or smell,
- Nasal congestion,
- Conjunctivitis (also known as red eyes)
- Sore throat,
- Muscle or joint pain,
- Different types of skin rash,
- Nausea or vomiting,
- Chills or dizziness.
Symptoms of severe COVID‐19 disease include:
- Shortness of breath,
- Loss of appetite,
- Persistent pain or pressure in the chest,
- High temperature (above 38 °C).
Other less common symptoms are:
- Reduced consciousness (sometimes associated with seizures),
- Sleep disorders,
- More severe and rare neurological complications such as strokes, brain inflammation, delirium and nerve damage.
- Maintain at least a 1-metre distance between yourself and others to reduce your risk of infection when they cough, sneeze or speak. Maintain an even greater distance between yourself and others when indoors. The further away, the better.
- Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal are essential to make masks as effective as possible.
Wearing a Mask:
- Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.
- Make sure it covers both your nose, mouth and chin.
- When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.
- Don’t use masks with valves.
Making Environment Safer.
- Avoid the 3Cs: spaces that are closed, crowded or involve close contact.
- Outbreaks have been reported in restaurants, choir practices, fitness classes, nightclubs, offices and places of worship where people have gathered, often in crowded indoor settings where they talk loudly, shout, breathe heavily or sing.
- The risks of getting COVID-19 are higher in crowded and inadequately ventilated spaces where infected people spend long periods of time together in close proximity. These environments are where the virus appears to spread by respiratory droplets or aerosols more efficiently, so taking precautions is even more important.
- Meet people outside. Outdoor gatherings are safer than indoor ones, particularly if indoor spaces are small and without outdoor air coming in.
- Avoid crowded or indoor settings but if you can’t, then take precautions:
- Open a window. Increase the amount of ‘natural ventilation’ when indoors.
- Wear a mask (see above for more details).
Long term effect of COVID-19
Some people who have had COVID-19, whether they have needed hospitalization or not, continue to experience symptoms, including fatigue, respiratory and neurological symptoms.
Vaccination of Covid-19
Due to various mutant versions of SARS-covid-19, it had been difficult to find out the working vaccine for it. After a long time effort of scientists, virologists, and various laboratories across the world finally the world get vaccines. At least 13 different vaccines (across 4 platforms) have been administered. Campaigns have started in 206 economies.
As per WHO, scientists around the world are developing many vaccines for COVID-19. These vaccines are all designed to teach the body’s immune system to safely recognize and block the virus that causes COVID-19.
Several different types of potential vaccines for COVID-19 are in development, including:
- Inactivated or weakened virus vaccines, which use a form of the virus that has been inactivated or weakened so it doesn’t cause disease, but still generates an immune response.
- Protein-based vaccines, which use harmless fragments of proteins or protein shells that mimic the COVID-19 virus to safely generate an immune response.
- Viral vector vaccines, which use a safe virus that cannot cause disease but serves as a platform to produce coronavirus proteins to generate an immune response.
- RNA and DNA vaccines, a cutting-edge approach that uses genetically engineered RNA or DNA to generate a protein that itself safely prompts an immune response.
Pfizer, Moderna, and Johnson&Johnson are the vaccines approved by the CDC and are actively using for the protection of the public. US government also helping vaccine to low economic countries.
