How air pollution can worsen post-covid complications


The SARS-CoV-2 infection is to blame for the Coronavirus (COVID-19) pandemic, which has ruined millions of lives and had a significant effect on global health systems.

Despite being recovered, some people nevertheless struggle to resume their usual lives and jobs because of the disease’s residual effects, which range in severity.

Instead of just affecting the lungs, as was once believed, the unique SARS-CoV-2 virus also affects the heart, brain, liver, kidneys, and gastrointestinal tract.

Most victims of the coronavirus disease (COVID-19) recovered in a few weeks. However, some individuals, even those with milder forms of the illness, experienced symptoms for a considerable amount of time later. These persistent medical issues are also referred to as Post Covid syndrome, Post Covid disorders, long-term COVID-19, and post-acute sequelae of SARS-COV-2 infection (PASC).  (source)

What is Post-Covid syndrome?

More than four weeks after receiving COVID-19, people may have a variety of new, recurring, or persistent symptoms, which are referred to as Post syndrome. The post-COVID-19 syndrome can cause disability in certain people and can linger for months or years.

According to research, between one month and one year after receiving COVID-19, 1 in 5 individuals between the ages of 18 and 64 had at least one medical issue that may be related to COVID-19. At least one medical problem that COVID-19 could bring on affects 1 in 4 adults aged 65 and over. 

Symptoms of Post-Covid Syndrome 

People with post-COVID problems may experience a variety of symptoms that last for up to four months after the infection.

  1. Multiorgan effect of Covid-19:-

The heart, lungs, kidneys, skin, and brain are just a few of the many body systems that might be affected by multiorgan impacts. Due to these side effects, COVID-19 patients may be more likely to experience the onset of new medical disorders like diabetes, cardiac problems, or neurological problems.

  • Lungs:- SARS-Cov-2 causes acute respiratory distress syndrome (ARDS). More air sacs may fill with fluid when COVID-19 pneumonia worsens because of leaks from the lungs’ small blood veins. Shortness of breath eventually develops and can result in ARDS, a kind of lung failure. People who are suffering from acute respiratory distress syndrome cannot breathe properly and may require a ventilator to circulate oxygen in their bodies. (sources)
  • Kidney:- Even those who didn’t have any underlying renal issues before contracting COVID-19 but are suffering from severe cases of the virus occasionally display indicators of kidney impairment. High protein or blood levels in the urine and abnormal blood tests are indicators of kidney issues in COVID-19 individuals. (sources
  • Heart:- Less oxygen can enter the circulation as the virus causes inflammation and fluid to fill the air sacs in the lungs. Blood pumping through the body requires more effort from the heart, which can be problematic for those with heart disease. Overworked hearts can stop working, and other organs, including the heart, can suffer from cell death and tissue damage from a lack of oxygen. (sources
  • Loss of taste and smell:- Because the senses of smell and taste are interconnected and the coronavirus can impact nose cells, having COVID-19 can produce anosmia, or a loss or distorting of one’s sense of smell or taste. Both before and after contracting COVID-19, a person may completely lose their sense of smell or taste or discover that familiar objects smell or taste weird, unpleasant, or unusual. (sources).
  1. Long covid:-

It includes a variety of symptoms that might continue for weeks or months.

The typical clinical symptoms of “long COVID” are weariness, brain fog, headaches, chronic loss of taste or smell, coughing, depression, low-grade fevers, muscular discomfort, and joint pain.

  1. Effects of COVID-19 treatment/hospitalization:-

Hospitalisation for COVID-19 has similar side effects to other life-threatening infections. Post-intensive care syndrome (PICS) causes significant weakness among them. Many of the patients who are suffering from these COVID-19 problems are improving over time.


Breathing polluted air might be really dangerous for people who had Covid- 19. Every year millions of healthy people get affected due to hazardous air pollution which can impact their health in a very negative way.  People who already had Covid have less immunity and they’re prone to get more respiratory issues and airborne disease transmission. 

The post-COVID-19 condition develops in people who have a history of likely or confirmed SARS-CoV-2 infection, often three months after the onset of Covid-19, with symptoms that extend for at least two months and cannot be accounted for by another diagnosis. Numerous symptoms that typically affect day-to-day functioning include fatigue, shortness of breath, cognitive impairment, and others. After first recovering from an acute COVID-19 episode, symptoms may develop suddenly, or they may continue after the initial sickness. Over time, symptoms may also change or recur.
