What is Corona Virus? What we do?
Coronavirus
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).
Coronavirus disease (COVID-19) is a new strain that was discovered in 2019 and has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
Symptoms
People may be sick with the virus for 1 to 14 days before developing symptoms. The most common symptoms of coronavirus disease (COVID-19) are fever, tiredness, and dry cough. Most people (about 80%) recover from the disease without needing special treatment.
More rarely, the disease can be serious and even fatal. Older people, and people with other medical conditions (such as asthma, diabetes, or heart disease), may be more vulnerable to becoming severely ill.
People may experience:
- Cough
- Fever
- Tiredness
- Difficulty breathing (severe cases)
Prevention
There’s currently no vaccine to prevent coronavirus disease (COVID-19).
You can protect yourself and help prevent spreading the virus to others if you:
Do
Wash your hands regularly for 20 seconds, with soap and water or alcohol-based hand rub
Cover your nose and mouth with a disposable tissue or flexed elbow when you cough or sneeze
Avoid close contact (1 meter or 3 feet) with people who are unwell
Stay home and self-isolate from others in the household if you feel unwell
Don't
Touch your eyes, nose, or mouth if your hands are not clean.
Treatments
There is no specific medicine to prevent or treat coronavirus disease (COVID-19). People may need supportive care to help them breathe.
Self care
If you have mild symptoms, stay at home until you’ve recovered. You can relieve your symptoms if you:
rest and sleep
keep warm
drink plenty of liquids
use a room humidifier or take a hot shower to help ease a sore throat and cough
Medical treatments
If you develop a fever, cough, and have difficulty breathing, promptly seek medical care. Call in advance and tell your health provider of any recent travel or recent contact with travelers.

টেক্সটাইল ইঞ্জিনিয়ারিং বা বস্ত্র প্রকৌশল নিয়ে বিস্তারিত
বস্ত্রকৌশল কি ও কেন
শিল্প প্রতিষ্ঠানের সব ক্ষেত্রেই প্রযুক্তির ব্যবহার বাড়ছে। একসময় যেখানে তাঁতে বুনে কাপড় তৈরি করা হত, এখন আর সেভাবে কাপড় তৈরি করে চাহিদা মেটানো যাচ্ছে না। কারণ এর পুরো প্রক্রিয়াটাই ব্যাপক সময়নির্ভর। তাই এখানেও মানুষ সাহায্য নিচ্ছে যন্ত্রের। সুতা থেকে পোশাক বানানোর এই প্রযুক্তিনির্ভর পুরো প্রক্রিয়াটিই বস্ত্র কৌশলের
