By now, researchers and health experts have gained a better understanding of the range of symptoms caused by COVID-19, which include fever, a dry cough, and of course, the dangerous inflammation of the respiratory system. Most of us know that COVID-19 can be much more severe than a typical flu, but lesser known are the mechanics behind how the virus causes pneumonia in its victims.
Today’s informative illustration, by scientific designer and animator Avesta Rastan, details the effects COVID-19 has on our lungs, from moderate to severe cases.
According to the World Health Organization (WHO), most people who contract COVID-19 only experience mild flu-like symptoms. Occasionally though, the infection can cascade into a severe case of pneumonia that can be lethal, especially for older people and those with underlying medical conditions.
Here’s what COVID-19 does to your body.
The virus, officially named SARS-CoV-2, enters the body – generally through the mouth or nose. From there, the virus makes its way down into the air sacs inside your lungs, known as alveoli.
Once in the alveoli, the virus uses its distinctive spike proteins to “hijack” cells. The primary genetic programming of any virus is to make copies of itself, and COVID-19 is no exception. Once the virus’ RNA has entered a cell, new copies are made and the cell is killed in the process, releasing new viruses to infect neighboring cells in the alveolus.
This process can occur initially without a person being aware of the infection, which is one of the reasons COVID-19 has been able to spread so effectively.
The process of hijacking cells to reproduce causes inflammation in the lungs, which triggers an immune response. As this process unfolds, fluid begins to accumulate in the alveoli, causing a dry cough and making breathing difficult.
For 80-85% of people infected by COVID-19, these symptoms will run their course much as they would with a case of the flu.
In 15-20% cases, the immune system’s response to inflammation in the lungs can cause what’s known as a “cytokine storm”. This runaway response can cause more damage to the body’s own cells than to the virus it’s trying to defeat, and is thought to be the main reason for why the conditions of young, otherwise healthy individuals can rapidly deteriorate.
If enough alveoli collapse, a patient to be placed on a ventilator for breathing assistance. Both acute respiratory distress syndrome (ARDS) and high-altitude pulmonary edema (HAPE) are being investigated as causes.
At this stage, the surfactant that helps keep alveoli from collapsing has been diluted, and fluid containing cellular debris is impairing the gas exchange process that supplies oxygen to our bloodstream.
In the most severe cases, systemic inflammatory response syndrome (SIRS) occurs as the protein-rich fluid from the lungs enters the bloodstream, resulting in septic shock and multi-organ failure. This is often the cause of death for people who have succumbed to a COVID-19 infection.
The Best Protection
Thankfully, COVID-19 isn’t a death sentence for most people who become infected, but the symptoms described above are not pleasant. Until a vaccine is developed, the best defense is avoiding infection altogether through frequent, thorough hand washing, and physical distancing as recommended by health authorities.

Visualizing the World’s Biggest Pharmaceutical Companies
The world’s biggest pharmaceutical companies are worth $4.1 trillion. Here we map the top 100 companies based on their market cap value.
Who are the World’s Biggest Pharmaceutical Companies?
Some of the world’s biggest pharmaceutical companies have played a central role in the COVID-19 pandemic.
However, it’s likely no surprise that the pandemic has also been great for many healthcare businesses. In fact, in 2020 alone, the world’s 50 largest pharmaceutical companies still combined for a whopping $851 billion in revenues.
In this graphic, using data from Companies Market Cap, we list the largest pharmaceutical companies in the world by market capitalization. It’s worth noting this list also includes healthcare companies that work closely with pharmaceuticals, including biotech, pharmaceutical retailers, clinical laboratories, etc.
Editor’s Note: A previous version of this graphic was missing some key companies such as GSK and AbbVie. They were unfortunately not included in the original source and we are now working to make sure there were no other smaller omissions. Thanks to all that sent in corrections.
The Pharmaceutical Leaders
To start, here are the top five biggest pharmaceutical companies in the world at the moment by market capitalization:
1. Johnson & Johnson
The pharmaceutical and consumer goods giant is worth $428.7 billion in market cap. They developed the third vaccine authorized for use in the U.S. and were named among the TIME100 Most Influential Companies List in 2021.
The Swiss pharmaceutical giant is at the forefront of oncology, immunology, infectious diseases, ophthalmology, and neuroscience. In 2019, Roche’s pharma segment sales rose by a healthy 16% to $53 billion.
Despite being the leading COVID-19 vaccine manufacturer in North America, Pfizer slid in the rankings to third place. The company has recently gained momentum, especially in the past quarter, with Q2’2021 revenues of $19.0 billion, reflecting a 86% operational growth from 2020.
4. Eli Lilly
Eli Lilly has taken a significant step towards establishing itself as a pharmaceutical industry leader. Having a market cap value of $125 billion in 2019, Eli Lilly has jumped to a current value of $214.9 billion, a significant growth of 72%.
The second-biggest pharmaceutical company out of Switzerland, Novartis has been the face of the pharma industry for about 25 years. The primary manufacturer for the most recognizable drugs on the market pulled in a revenue of over $48 billion in 2020, a 3% increase compared to 2019.

World’s Largest Pharmaceutical Exporters and Importers
According to the World Trade Organization (WTO), these countries exported the most number of pharmaceuticals in the year 2019:
|Rank||Country||Export Value (US$B)|
In contrast, here are the biggest importers over the same period.
|Rank||Country||Import Value (US$B)|
This position is hardly surprising for the U.S., where six of the world’s top 10 pharmaceutical companies are headquartered. The country also captures 45% of the global market.
The Future of Pharmaceutical Companies
If the response to the COVID-19 pandemic has taught us anything, it is that in building a patient-centered future, the pharmaceutical industry plays a key role. It has to constantly find new ways to customize medicines while researching and developing new tools and drugs.
By embracing disruptive technologies like 3D printed drugs, artificial intelligence guided therapies, and preventive medicine while working with regulatory agencies, the pharmaceutical companies will benefit from having a digital revolution.
Furthermore, emerging markets will have a more significant say in the global pharmaceutical market in the coming years. Even though ‘big pharma’ will keep raking in the massive profits they do every year, their reliance on countries like Brazil and India for research and drug production will significantly impact the years to come.
When Will Your Country Recover from the Pandemic?
The path to COVID-19 recovery varies worldwide—some countries have already recovered, while others will not be back to normal for years.
What started as a novel virus in China quickly became a sweeping disease that shut down the world and put a 1.5 year halt on the global economy.
But while some countries’ economies are already back to normal, others are lagging far behind.
COVID-19 Recovery Timelines, by OECD Country
This chart using data from the OECD anticipates when countries will economically recover from the global pandemic, based on getting back to pre-pandemic levels of GDP per capita.
Note: The categorization of ‘advanced’ or ‘emerging’ economy was determined by OECD standards.
The Leaders of the Pack
At the top, China and the U.S. are recovering at breakneck speed. In fact, recovering is the wrong word for China, as they reached pre-pandemic GDP per capita levels just after Q2’2020.
On the other end, some countries are looking at years—not months—when it comes to their recovery date. Saudi Arabia isn’t expected to recover until after Q1’2024, and Argentina is estimated to have an even slower recovery, occurring only after Q2’2026.

|🇷🇺 Russia||After Q2 2021||Emerging|
|🇨🇳 China||After Q2 2020||Emerging|
|🇸🇦 Saudi Arabia||After Q1 2024||Emerging|
Most countries will hit pre-pandemic levels of GDP per capita by the end of 2022. The slowest recovering advanced economies—Iceland and Spain—aren’t expected to bounce back until 2023.
Four emerging economies are speeding ahead, and are predicted to get back on their feet by the end of this year or slightly later (if they haven’t already):
- 🇷🇺 Russia: after Q2’2021
- 🇨🇱 Chile: after Q3’2021
- 🇮🇳 India: after Q4’2021
- 🇮🇩 Indonesia: after Q4’2021
However, no recovery is guaranteed, and many countries will continue face setbacks as waves of COVID-19 variants hit—India, for example, was battling its biggest wave as recently as May 2021.
Why are some countries recovering faster than others? One factor seems to be vaccination rates.
|Country||Doses Administered per 100 People||Total Doses Administered||Percent of Population Fully Vaccinated|
|🇬🇧 United Kingdom||122||81,438,892||53%|
|Trinidad and Tobago||27||375,924||11%|
|Saint Vincent and the Grenadines||23||25,509||–|
|West Bank & Gaza||20||958,519||9%|
|São Tomé and Príncipe||18||37,716||5%|
|Bosnia and Herzegovina||14||470,218||5%|
|Republic of the Congo||3||163,742||–|
|Central African Republic||1.7||78,685||–|
|Papua New Guinea||0.6||51,170||<0.1%|
As of July 16th, 2021.
The higher the rate of vaccination, the harder it is for COVID-19 to spread. This gives countries a chance to loosen restrictions, let people get back to work and regular life, and fuel the economy. Additionally, the quicker vaccines are rolled out, the less time there is for variants to mutate.
Another factor is the overall strength of a country’s healthcare infrastructure. More advanced economies often have more ICU capacity, more efficient dissemination of public health information, and, simply, more hospital staff. These traits help better handle the pandemic, with reduced cases, less restrictions, and a speedy recovery.
Finally, the level of government support and fiscal stimulus injected into different economies has determined how swiftly they’ve recovered. Similar to the disparity in vaccine rollouts, there was a significant fiscal stimulus gap, especially during the heat of the pandemic.
Recovering to Normal?
Many experts and government leaders are now advocating for funneling more money into healthcare infrastructure and disease research preventatively. The increased funding now would help stop worldwide shut downs and needless loss of life in future.
Time will tell when we return to “normal” everywhere, however, normal will likely never be the same. Many impacts of the global pandemic will stay with us over the long term.
