Coronavirus Second Wave In The World?

Coronavirus second wave in the world high affected countries. Includes America, Europe Asia. But especially corona second wave Pakistan and other few countries. but most affected by the second wave in Pakistan and India. So highly affected by the second wave of the coronavirus. And when the virus is outside of the host body. So they not able to resist destruction factors. Be it temperature as they are inactive outside of the host. The host is a prescribed parasite. You may say they are unarmed. When in the environment how Coronavirus affects the human body. And how its treatment is possible.  A unique feature of this virus causes both upper and lowers respiratory tract infections. How Coronavirus Affect And Treatment.

Entry and reaction on the immunity system.

After insertion into the body through aerosol transmission. So any other transmission attaches to a specific cellular receptor(ACE-2). Located in the lungs on the surface of type 2 alveolar cells) via the spikes protein. How Coronavirus affects the human body.


covid-19 second wave 2020

  • Changes in alveolar cells and replication of the virus.

Transformational changes, leading to the fusion between the virus and the cell membrane. It causes the release of nucleocapsid into the host cells. And alveolar cells start to die.

  • Transcription and Translation.

Alteration of DNA and production of proteins and certain specific enzymes.Alteration of cells function and production.

  • Cytotoxic effects.

Release of excess cytokines. And chemokines-1B, IL-6, IL-7, IL-8, IL-9, IL-10, and TNF-alpha. And acute phase reactants increase like ESR, CRP, and Procalcitonin.

  • C-reactive protein  

CRP is a protein made by the liver and sent to the bloodstream. Blood levels may be higher when you inflammation or infections. Because CRP levels often go up before you have symptoms of pain or .


Cause of death due to complication:

  • Cytokine storm syndrome.
  • Severe acute respiratory distress syndrome (SARS).
  • Fulminate myocarditis ( Cardiac affinity).

Symptoms of covid-19:

People who catch Covid-19 can be placed into four broad categories.

  1. The least serious are those people who are subclinical and have the virus but no clinical signs.
  2. Those who get an in the upper respiratory tract. They have a and or maybe milder. Symptoms like headaches or conjunctivitis.
  3. This is the largest group of those who would be positive. For COVID-19 and people most likely to present in the .

Will develop severe illness that features Pneumonia

How does pneumonia develop?

The lining of the respiratory tree becomes injured. Causing is inflammation. This, in turn, irritates the nerves in the lining of the airway. Just a speck of dust can stimulate a .

But it gets worse. It goes past the lining of the airway and goes to the gas exchange unit. If they become infected they respond by pouring out inflammatory material into the air sac. If the air sac becomes inflamed. This causes a flood of inflammatory material into the lungs and we end up with pneumonia.

Starting symptoms of covid-19:

  • .
  • .
  • Fatigue.
  • Sputum production.
  • Shortness of .
  • .
  • Headaches.
  • .
  • Nausea and vomiting.
  • Nasal congestion.
  • Diarrhea.
  • Hemoptysis.
  • Conjunctival congestion.

Who is affected the most?

  1. Immunocompromised individuals.
  2. Chronic disorders.
  • Bronchial Asthma.
  • Diabetes.
  • Cardiovascular patients.
  1. Old age people.

Treatment of coronavirus.

Nothing has postulated officially.

Hospitalization only for severe cases.

  1. Supportive treatment.
  • Maintain airway, breathing, circulation.
  • Ventilation is required.
  • Isolation.
  • Correction of electrolyte imbalance.
  • Correct temperature.


Coronavirus of covid-19 starts from china. Coronavirus a type of virus that is affecting the human body very quickly. And it’s very dangerous for all the people who have a low immunity system. There are a few main precautions of coronavirus by which people can protect themselves. So maintain airway, breathing, circulation. Ventilation is required and Isolation. coronavirus treatment.
