Coronavirus symptoms day by day 

What are the symptoms of COVID-19 and how to avoid it? 

Fever, cough, and difficulty in breathing are the main symptoms of corona disease. The coronavirus continues to spread around the world and so far the number of confirmed cases is close to 7.5 million and the number of deaths is more than 422,000. If you look at Pakistan, the number of people affected by Corona is more than one lakh, while more than two thousand people have died as a result of this epidemic. According to researchers, 80% of people in the world affected by Corona have only mild symptoms, and those with these symptoms are in the minority. The virus affects the lungs and the two main symptoms are fever and persistent dry cough. According to the British National Institutes of Health, a dry cough means a sore throat that does not produce mucus. A persistent cough means that you have been coughing for about an hour or you have had at least three cough attacks in 24 hours, meaning your cough is longer than normal. It can also result in shortness of breath, often called chest tightness, difficulty breathing, or suffocation. If your body temperature is above 37.8 degrees Celsius or 98.6 degrees Fahrenheit, you have a fever. Fever can cause your body to become hot, you may catch a cold or shiver. Symptoms of sore throat, headache, and diarrhea have also been found in the victims, while some patients have also complained of an impaired sense of taste and smell. It usually takes five days for a patient to show symptoms, but in some people, they appear late. According to the World Health Organization, the period from infection to the onset of symptoms is 14 days, but some researchers say it can be up to 24 days. 

How many patients showed no symptoms? 

Chinese scientists believe that some people can spread the infection even before the symptoms appear in themselves. According to a recent study published in the British Medical Journal, 78% of people infected with COVID-19 did not have obvious symptoms, meaning they were asymptomatic in medical terms. The results of this study are consistent with the results of a study conducted in this Italian village which became a major center of this epidemic in Corona. About 50 to 75 percent of the patients did not show any symptoms, but they became a major cause of its spread. Meanwhile, according to the results of the World Health Organization's examination of 56,000 patients: Eighty percent had mild symptoms, such as fever and cough, and some had pneumonia. Severe symptoms were found in 14% and these patients had severe difficulty in breathing. 06% were critically ill with lung and other vital organs failing and at risk of death. Most people infected with the coronavirus recovered after taking rest as well as taking painkillers such as paracetamol. If you have a fever, cough, or difficulty breathing, you should see a doctor as this may be due to a respiratory infection or something else. When do I need to go to the hospital? The main reason people have to go to the hospital in COVID-19 is difficulty in breathing. At the hospital, doctors will examine your lungs to see how affected they are. Most sick people are transferred to an intensive care unit designed specifically for the seriously ill. Coronavirus patients are given oxygen, which is given through a face mask or a nasal tube. Extremely sick patients are transferred to a ventilator and this device injects more oxygen into their lungs through a tube inserted through a hole in the mouth, nose, or throat. 

Who is most at risk of contracting Covid-19?

Older people and people who already have a disease such as asthma or diabetes or heart disease can be infected more quickly with the coronavirus. Men have a relatively higher risk of contracting the virus than women. It can take a few days to several weeks for minor patients to recover, but if someone is in intensive care in a hospital and beyond, it can take several months for them to recover.

How deadly is the coronavirus?

According to a study published in the medical journal Lancet, the death toll from COVID-19 was initially one to two percent, but now it is 0.66 percent. This is far more than the number of people who die from the common flu. The death toll from influenza is 0.01% worldwide, But it is not currently possible to estimate the actual death toll from Corona, as many of its patients have not been diagnosed. 



How can we protect ourselves?

The World Health Organization says: Wash your hands with soap or gel that can kill the virus. Cover your mouth when coughing or sneezing, preferably with a tissue, and wash your hands immediately afterward to prevent the virus from spreading. Don't go near people who are coughing, sneezing or have a fever. Their mouths can emit drops of the virus that can be in the air. Keep a distance of at least one meter or three feet from such people. Stay at home if you feel unwell. Get medical help immediately if you have a fever, cough, or difficulty in breathing. Follow the instructions of the medical authorities. 

How long will the vaccine for the treatment of COVID 19 be made?

BBC Health and Science Correspondent: Although more than 200,000 people worldwide have died from COVID-19, no drug has yet been developed that can help doctors treat the disease.

What is being done to find a cure?

More than 150 drugs are being researched around the world. Most of them are already being used to treat various diseases and are now being tested against the virus. The World Health Organization (WHO) has launched a 'solidarity trial' aimed at identifying reliable treatments. The UK claims that its trial is the largest in the world, with more than 5,000 patients still taking part. Many research centers around the world are trying to find a cure for the blood of those who have recovered from Corona. 

What kind of medicine will work?

Three broad perspectives are being worked on in this regard: Use of antiviral drugs that directly affect the ability of the coronavirus to spread inside the body. Medications that can improve the immune system because the patient becomes more ill when his immune system overreacts and thus harms the whole body. Antibodies that can attack the virus, whether taken from the blood of a healthy person or made in a laboratory.

Can HIV medicine cure Corona-virus?

There is a lot of talks that HIV drugs, lopinavir, and ritonavir, may be effective against the coronavirus, but no concrete evidence has emerged. There was some evidence that it could work in the laboratory, but research on humans has been disappointing. This combination of the two drugs did not accelerate the recovery from the coronavirus, nor did it reduce the number of deaths, nor did it reduce the severity of the virus in COVID-19 patients.

Can malaria medicine stop coronavirus?

Malaria drugs are part of trials by both the World Health Organization and the United Kingdom. Chloroquine and related hydroxychloroquine may have antiviral and immune-calming properties. The drugs appeared to be a possible cure for the coronavirus. President Trump made that claim, but there is no hard evidence that it is effective. Hydroxychloroquine is also used for joint pain as it can help monitor the immune system. Laboratory tests have shown that it can affect the coronavirus, and doctors have suggested that it may improve patients. However, according to the World Health Organization, there is no conclusive evidence that these drugs are effective. However, the trial was indeed conducted on very sick people (about a quarter of whom later died). Therefore, it can be said that it was too late to stop the infection through medicine at that time.

What about immune-enhancing drugs?

If the immune system overreacts to the virus, it can cause inflammation throughout the body. This is enough to stimulate the immune system against infection, but overuse can be fatal to the whole body. The World Health Organization is reviewing the Interferon Beta trial. This medicine is used to reduce inflammation. Interferons are chemicals that the body releases when it is attacked by a virus. The UK recovery trial is also investigating Dexa Methasone. It is a steroid that reduces inflammation.

Can corona be treated with the blood of healthy people?

This is how you take blood plasma (this is the part that contains the antibodies) and insert it into the sick person's body as a treatment. It has treated 500 patients in the United States and other countries are joining.

How long will the treatment last?

It is too early to say when medicine will come to us to treat the coronavirus. But we will start getting the results of the trials in the next few months. It will be a long time before we know if a vaccine is effective against it. The vaccine protects against infection, does not cure it. This is also because doctors are testing drugs that have already been developed and are known to be safe to use. Vaccine researchers, on the other hand, are starting from scratch. Some brand new experimental Coronavirus drugs are also being tested in the laboratory, but they are not yet ready to be tested on humans.

Why do we need corona treatment?

The most obvious reason is to save human lives, but it can also help reduce some lockdown measures. Effective treatment can also make the coronavirus a mild disease. If it reduces the number of patients who may need a ventilator, it will also reduce the burden on the intensive care units in hospitals, and people's lives will no longer need to be controlled so strictly.

How are doctors treating patients?

If someone has got the coronavirus, for most people it will be mild to moderate, which can be treated by resting at home, taking paracetamol, and drinking plenty of water. But some people need extreme hospital treatment, including oxygen assistance (ventilation).
