Top Covid 19 Symptoms have changed, Study Finds

The coronavirus disease 19 (COVID-19), an extremely contagious, fatal, and infectious. It is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that began in Wuhan, China, and spread across the globe. Although the beginning and point of transmission from an intermediate root cause to humans are unknown, the rapid transfer from one human to another has been widely confirmed. Clinical trials have not shown any antiviral drugs or vaccines to be applicable against COVID-19. Furthermore, only a few antiviral, broad-spectrum medicines have been tested against COVID-19 in medical studies, improving the clinical situation

Mode of transmission for the Covid 19

The coronavirus is now known to spread by the airborne transmission and pathogens produced whenever an infectious individual breathes, chats, laughs, screams coughs, or belches. Highly infectious molecules can stick around in the air and accumulate indoors, particularly in crowded spaces with minimum ventilation. In contrast, bigger droplets may fall in a short amount of time. Due to this, preventing COVID-19 necessitates the use of masks, excellent hand hygiene, and disconnection.

How much time does COVID-19 Require to Reproduce?

Victims start to feel sick from the second day to fourteen days after coming into touch with the virus. A patient with the coronavirus is contagious. It stays between ten and twenty days after exposure, up to two days before the symptoms appear, based on their immunity and the depth of their illness.

What were the Initial Coronavirus Symptoms?

The initial covid 19 symptoms include-

Cough − A coronavirus (COVID-19) is a virus that affects the lungs and can cause you to develop a dry cough. Some patients may also have a cough that produces phlegm, which is not always the same as a cold or sore throat.

Fever − Fever is a classic COVID-19 symptom where the body uses fever as one of its defenses against infection. Not everyone who contracts the disease will experience a fever, though. Fever can appear between two days and two weeks after infection with the virus.

Fatigue − Fatigue is a common side effect of COVID-19 infection. It can cause pain and weariness that resemble brain fog in some people with severe illnesses. Symptoms can last for weeks or even months, depending on the type of infection you are suffering from.

Appetite loss − Appetite loss is a precursor of COVID-19. It typically lasts four days for persons over 35, although it can last up to a week or more, whereas I t usually lasts two to three days for those under 35 and becomes better in a week.

Sputum Production − A dry cough is one of the most common early signs of COVID-19, and phlegm generation is unusual. Sputum suctioning is necessary because the sputum may progressively rise as the condition worsens and because it is viscous and challenging to expectorate on one's own.

Muscle and body Pain − About 1 in 3 COVID-19 patients will feel bodily pains, and those between the ages of 16 and 65 are more likely to experience this symptom than children or elderly persons. Body pains are frequently the first sign of the illness and can last up to five days.

Occurrence of Symptoms

Occurrence of different symptoms of Covid 19 are 83 to 99 percent fever, 59 to 82 percent cough, fatigue and weariness of 44 to 70 percent, 40 to 84 percent loss of appetite − sputum production counts 28 to 33 percent, and muscle or bodily pains occurring to 11 to 35 percent.

Other Covid symptoms include respiratory issues or shortness of breath, sore throat, a recent change in taste or smell, headache, or vomiting. Unfortunately, among certain patients, COVID-19 may result in death, renal failure, irreversible damage to the lung and heart muscles, problems with the neurological system, and respiratory organ failure.

It has been more than two years since the first outbreak of Covid 19, and now the initial symptoms have changed as new variants of Covid occur due to-.

Viral factors − include replication speed, transmission methods, and so forth. As the virus develops, these "viral factors" alter.

Host factors −  These are unique to the diseased person. They include host parameters that can be influenced by host factors such as age, gender, medicines, food, exercise, and stress.

Immunization −  Because older age groups have higher immunization coverage rates, more COVID instances are now being reported among younger persons, who also have milder symptoms on average.

What are the new Covid-19 Symptoms?

Along with the previous symptoms, new Covid symptoms were added which include-

Congestion/stuffy nose  Runny nose and congestion are typical symptoms of COVID-19 in the modern period, especially in those who have been immunized and boosted. The top five symptoms reported for a new COVID infection, together with earlier symptoms, were determined by the results to include a runny nose. In addition to making things worse, it can cause a persistent cough as too much mucus runs down the back of the throat (post nasal drip).

Nausea  People frequently ignore the fact that some individuals' initial clinical sign of COVID-19 is nausea or vomiting. It is now identified that SARS-CoV-2 can affect the gastrointestinal tract in addition to the lungs. The digestive wall has been revealed to have greater levels of its Angiotensin-converting enzyme 2 (ACE2), which is the host receptor, is a gateway to infection and may cause nausea and vomiting.

Diarrhoea  People with COVID-19 frequently have diarrhoea. Studies of a trusted Source looked at 206 individuals with a mild case of COVID-19.  They discovered that 69 participants had both stomach and respiratory symptoms, whereas 48 persons solely experienced digestive symptoms amongst which 19.4% of the 117 persons who had stomach discomfort overall reported diarrhea as their initial symptom.


Seek emergency medical treatment for any severe symptoms, such as shortness of breath and vomiting. Many clinics offer phone or video visits to stop the virus from spreading. It's wise to stay away from the hospital. Even if you only exhibit minor symptoms, you can still spread the illness to others, even medical professionals.
