Now days the most gossips are about COVID-19 in which covered the whole world in grip. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
The only solution of COVID-19 is:
- Clean your hands often. Use soap and water, or an alcohol-based hand rub.
- Maintain a safe distance from anyone who is coughing or sneezing.
- Wear a mask when physical distancing is not possible.
- Don’t touch your eyes, nose or mouth.
- Cover your nose and mouth with your bent elbow or a tissue when you cough or sneeze.
- Stay home if you feel unwell.
- If you have a fever, cough and difficulty breathing, seek medical attention.
The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol-based rub frequently and not touching your face.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
Cases have been reported?
Since March 16, more cases were registered outside mainland China than inside, marking a new milestone in the spread of the global pandemic.
The virus has spread from China all around the world, prompting the WHO to label the COVID-19 outbreak a pandemic.
Human-to-human transmissions became evident after cases were recorded with no apparent link to China.
Here are the countries that have so far confirmed coronavirus cases:
United States – 6,723,933 cases, 198,570 deaths
India – 5,214,677 cases, 84,372 deaths
Brazil – 4,495,183 cases, 135,793 deaths
Russia – 1,086,955 cases, 19,128 deaths
Colombia – 750,471 cases, 23,665 deaths
Peru – 750,098 cases, 31,146 deaths
Mexico – 688,954 cases, 72,803 deaths
South Africa – 657,627 cases, 15,857 deaths
Spain – 640,040 cases, 30,495 deaths
Argentina – 613,658 cases, 12,656 deaths
France – 467,421 cases, 31,257 deaths
Chile – 442,827 cases, 12,199 deaths
Iran – 416,198 cases, 23,952 deaths
United Kingdom – 388,416 cases, 41,821 deaths
Bangladesh – 345,805 cases, 4,881 deaths
Saudi Arabia – 328,720 cases, 4,430 deaths
Iraq – 311,690 cases, 8,408 deaths
Pakistan – 305,031 cases, 6,415 deaths
Turkey – 299,810 cases, 7,377 deaths
Italy – 294,932 cases, 35,668 deaths
Where did the virus originate?
Chinese health authorities are still trying to determine the origin of the virus, which they say likely came from a seafood market in Wuhan, China where wildlife was also traded illegally.
On February 7, Chinese researchers said the virus could have spread from an infected animal species to humans through illegally-trafficked pangolins, which are prized in Asia for food and medicine.

Less common symptoms:
- aches and pains
- sore throat
- loss of taste or smell
- a rash on skin
- difficulty breathing or shortness of breath
- chest pain or pressure
- loss of speech or movement
Structure and life cycle of Covid-19
COVID-19 is a spherical or pleomorphic enveloped particle containing single-stranded (positive-sense) RNA associated with a nucleoprotein within a capsid comprised of matrix protein. The envelope bears club-shaped glycoprotein projections.
There are three or four viral proteins in the coronavirus membrane. The most abundant structural protein is the membrane (M) glycoprotein; it spans the membrane bilayer three times, leaving a short NH2-terminal domain outside the virus and a long COOH terminus (cytoplasmic domain) inside the virion.The spike protein (S) as a type I membrane glycoprotein constitutes the peplomers. In fact, the main inducer of neutralizing antibodies is S protein. Between the envelope proteins with exist a molecular interaction that probably determines the formation and composition of the coronaviral membrane. M plays a predominant role in the intracellular formation of virus particles without requiring S. In the presence of tunicamycin coronavirus grows and produces spikeless, noninfectious virions that contain M but devoid of S.
Food during COVID-19
- When cooking and preparing food, limit the amount of salt and high-sodium condiments (e.g. soy sauce and fish sauce)
- Limit your daily salt intake to less than 5 g (approximately 1 teaspoon), and use iodized salt.
- Avoid foods (e.g. snacks) that are high in salt and sugar.
- Limit your intake of soft drinks or sodas and other drinks that are high in sugar (e.g. fruit juices, fruit juice concentrates and syrups, flavoured milks.
- Choose fresh fruits instead of sweet snacks such as cookies, cakes and chocolate
Pakistan fears 2nd wave amid rise in coronavirus cases. Country records 908 new infections, highest since July 30
Pakistan on Thursday recorded 908 new coronavirus cases, the highest daily number since July 30.
With 908 new infections, the nationwide caseload reached 331,108, while 16 more virus-related deaths pushed the tally to 6,775.
On July 30, the South Asian country of over 200 million people recorded 903 cases of the novel virus, a figure which then started to decline.
Amid a resurgence in cases across Europe and other countries, there are fears of a second wave in Pakistan as well. To contain the outbreak, the government has made wearing of masks mandatory in public places.
Authorities also announced the shutting of all parks and entertainment venues by 6 p.m. and markets, shopping centers, restaurants and banquet halls by 10 p.m. nationwide.
“After more than 70 days, the national Covid positivity ratio was higher than 3% yesterday. NCOC [National Command and Operations Centre] has tightened restrictions on some high-risk public activities. However, the rising spread of the disease can only be controlled if people believe in the need for precautions.”
