Pneumonia has been feared for its deadliness and unpredictability. In the late 19th and early 20th centuries, it claimed countless lives. Sir William Osler, often called the father of modern medicine, once referred to pneumonia as “the most fatal of all acute diseases,” as it was responsible for the death of one in four individuals infected during the Civil War.

Though medical advances have significantly reduced the mortality rate, pneumonia still presents a major global health concern. According to the Centers for Disease Control and Prevention (CDC), it sends over 1.4 million Americans to the emergency room annually and causes around 41,000 deaths in the U.S. alone.

So, what exactly is pneumonia, how does it spread, and—most importantly—is it contagious?

Pneumonia is an inflammatory condition of the lung tissue, most often caused by infections. It can affect one or both lungs and can range from mild to life-threatening, especially in vulnerable populations like the elderly, young children, or those with underlying health conditions.

There are several types of pneumonia, classified based on their causes—bacterial, viral, and fungal—and each has distinct patterns of transmission and severity.

What Causes Pneumonia?

Pneumonia is not a single disease but a syndrome resulting from various infectious agents:

Bacterial Pneumonia: This is the most common type, often developing as a secondary infection after a cold or flu. Streptococcus pneumoniae is the most frequent culprit.

Viral Pneumonia: Caused by viruses like influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (COVID-19), this type often starts in the upper respiratory tract and spreads to the lungs.

Fungal Pneumonia: This type is less common and usually affects individuals with weakened immune systems. It's typically contracted through environmental exposure, such as to soil or bird droppings.

Is Pneumonia Contagious?

The answer is both yes and no—depending on the cause. Viral and bacterial pneumonia are contagious forms of the illness, capable of spreading through respiratory droplets when an infected person coughs, sneezes, or even talks. These droplets, once inhaled, can allow harmful pathogens to infiltrate the lungs and cause infection. In contrast, fungal pneumonia is not contagious and cannot be transmitted from person to person. Instead, it is typically contracted by inhaling spores present in the environment, often found in soil or bird droppings. However, being exposed to a contagious form of pneumonia doesn't necessarily mean an individual will become ill. People with strong immune systems can often fend off the infection without developing symptoms. Those with weakened immunity—such as older adults, young children, or individuals with chronic health conditions—are more susceptible to serious illness from these infections.

Early Warning Signs You Shouldn’t Ignore

Pneumonia can be insidious. It often begins with symptoms that mimic the flu: headache, fatigue, and fever. But as the infection progresses, signs become more serious:

• Persistent cough with green, yellow, or even bloody mucus
• Shortness of breath
• Chest pain, especially when breathing or coughing
• High fever, chills, and night sweats
• Confusion, especially in the elderly
• Nausea or loss of appetite

The severity of symptoms often depends on the individual's age, overall health, and the type of pneumonia contracted.

What Is "Walking Pneumonia"?

Walking pneumonia—medically known as Mycoplasma pneumoniae—is a milder form of bacterial pneumonia. It’s dubbed “walking” because people often feel well enough to carry on with their daily routines despite being infected.

Though it’s less severe, it is still contagious and can spread in schools, workplaces, and homes. Symptoms can linger for weeks and include a dry cough, low-grade fever, and fatigue. It's often mistaken for a common cold, which makes controlling its spread more difficult.

Certain groups are more prone to catching pneumonia or suffering severe complications:

• Adults over age 60
• Children under age 2
• Hospitalized patients or those in long-term care facilities
• Individuals with chronic illnesses such as asthma, diabetes, or heart disease
• Smokers and people with compromised immune systems

Seasonality also plays a role—cases spike during colder months as people spend more time indoors in close proximity, facilitating the spread of germs.

How Is Pneumonia Diagnosed and Treated?

Doctors diagnose pneumonia through a combination of clinical examination, chest X-rays, and laboratory tests, including blood work and sputum analysis. The treatment approach depends on the underlying cause of the infection. Bacterial pneumonia is typically treated with antibiotics, and most patients recover within a few days to weeks if treated promptly. Viral pneumonia, on the other hand, is managed with antiviral medications along with supportive care such as rest, hydration, and fever-reducing medications. Fungal pneumonia requires antifungal medications and often involves a longer recovery period. In more severe cases—especially when oxygen levels drop or complications develop—hospitalization may be necessary to ensure proper medical support and monitoring.

How Can You Protect Yourself?

Prevention plays a crucial role in reducing pneumonia cases and severity:

• Pneumococcal vaccine is recommended for older adults and people with certain medical conditions.
• Flu shots help prevent influenza, a major cause of viral pneumonia.
• COVID-19 and RSV vaccines also play a preventive role.
• Wash hands regularly, avoid touching your face, and use hand sanitizer when soap isn't available.
• Don’t smoke, limit alcohol, eat a nutrient-rich diet, and ensure adequate sleep to support a strong immune system.
• Keeping diseases like diabetes, COPD, and heart conditions under control reduces vulnerability.

While pneumonia may not be the lethal giant it once was, it still commands attention—particularly for its contagious potential. Understanding the ways it spreads, the differences between its types, and how to recognize and respond to symptoms can make a world of difference.

When you hear of the drug lord Pablo Escobar, you think of someone uncatchable, beyond the law. However, it is because of such a personality that we often forget that he too has everyday problems like us, including health issues, which may have cost their lives too.

"Gastritis won't leave me alone," was one of the phrases the drug lord mentioned during the calls he had with his son and wife. One day, these were the calls that made it possible to catch him. Not just him, but also Ecuador's wanted criminal 'Fito', José Adolfo Macias Vilamar, who is the leader of Los Choneros too suffered from the same. On June 25, he was finally captured.

Drug Lords And Heart Diseases

It is Fito's medicines that gave him away. It was in the bunker of his house, or the appropriate word for it would be a hole, out of which Fito appeared. But, how did the authority know he would be in that hole, in the property? The authorities found products for heartburn and gastritis, such as Diatrol, Dexopal, and Omeprazole. This is what made them certain that Fito in fact was there. They also found medicines for treating skin conditions, such as Platsul and Itrafung, an insulin used by him to treat his diabetes.

"Fito has a serious gastritis problem and is taking some medication," said Interior Minister John Reimberg. Gastritis and heartburn was also suffered by the founder of Medellín cartel, Escobar.

After escaping from La Catedral in 1992, Escobar began hiding from authorities without the power he had during much of his criminal heyday, which prevented him from accessing the drugs he used to treat his gastritis.

What Is Gastritis?

As per John Hopkins Medicine, it is inflammation of the stomach lining. Your stomach lining is strong. In most cases, acid does not hurt it. But it can get inflamed and irritated if you drink too much alcohol, have damage from nonsteroidal anti-inflammatory drugs (called NSAIDs), or smoke.

What May Have Caused It?

For Drug lords, lavish parties, alcohol use, and extreme stress to find an escape is common. These are the exact causes of gastritis.

Lifestyle habits that can cause gastritis include:

• Drinking too much alcohol
• Smoking
• Extreme stress. This can be from serious or life-threatening health problems
• Long-term use of aspirin and NSAIDs

Health issues that too could lead to this:

• Infection caused by bacteria or viruses
• Major surgery
• Traumatic injury or burns

Diseases like autoimmune disorders, where you immune system attacks your body's healthy cells by mistake, or chronic bile reflux, where bile backs up into your stomach and food pipe (esophagus) could also cause gastritis.

Common Symptoms

• Stomach upset or pain
• Belching and hiccups
• Nausea and vomiting
• Feeling of fullness or burning in your stomach
• Loss of appetite
• Blood in your vomit or black stool. This is a sign that your stomach lining may be bleeding

Could It Lead To Complications?

Chronic gastritis hurts your stomach lining. It can raise your risk for other health problems. These include:

• Peptic ulcer disease. This causes painful sores in your upper digestive tract
• Gastric polyps. These are small masses of cells that form on the inside lining of your stomach
• Stomach tumors. These can be cancer or not cancer (benign)
• A hole (perforation) of the stomach

Menstrual products have come a long way—from homemade cloth rags and belts to silicone menstrual cups and sleek, leak-proof underwear. The history of these products is as much about medical innovation as it is about cultural taboos, social shifts, and gendered marketing. While nearly half the world menstruates at some point, the journey toward safer, dignified, and sustainable period care has been anything but straightforward.

Ancient Origins: Creativity and Cultural Beliefs

Long before commercial products existed, women relied on locally available materials. In ancient Greece, tampon-like devices were reportedly made using lint wrapped around light wood. Egyptian women fashioned internal devices from softened papyrus, while Roman women used wool or cotton pads secured with belts. Meanwhile, Native American women used moss and buffalo skin, and in Equatorial Africa, grass rolls absorbed menstrual blood.

However, these were not necessarily used openly. Menstruation was frequently wrapped in superstition and shame. Ancient texts reveal contradictory beliefs: while Egyptian medical papyri regarded menstrual blood as medicinal, Roman and early Christian texts often considered it impure, even dangerous.

19th Century: Cloth Pads and the Birth of Sanitary Belts

By the 1800s, European and American women commonly used reusable cloth rags made from flannel or linen. These were washed and reused but posed hygiene concerns. The late 19th century saw the invention of the sanitary belt—a strap-on belt that held a pad in place. Brands like Southalls’ Shaped Towel Suspender marketed these belts for women “travelling by land or sea.”

In 1896, Johnson & Johnson launched Lister’s Towels, the first disposable sanitary napkins. But cultural stigma around menstruation kept them from selling well; women were reluctant to ask for them in stores.

Early 20th Century: From Warfront to Women’s Needs

World War I brought an unexpected breakthrough. Nurses discovered that cellulose bandages, used to stop bleeding on the battlefield, were highly absorbent and cheap. This innovation led to the Kotex sanitary pad, marking one of the first commercially successful disposable period products.

In the 1920s, Fax tampons emerged, though still rudimentary. The most transformative moment came in 1933, when Earle Haas patented the modern tampon with an applicator. Soon after, Gertrude Tendrich, founder of Tampax, bought the patent and established the brand. Even so, tampons faced social resistance, particularly from conservative groups concerned about virginity and morality.

Mid-20th Century: Belts, Pads, and Patents

Through the mid-1900s, many women still used sanitary belts. African-American inventor Mary Kenner created an adjustable version in 1956, complete with a moisture-proof pocket. Sadly, her patent was ignored for decades due to racial discrimination.

In the 1970s, beltless pads with adhesive strips revolutionized convenience. Pads now came in various sizes—mini, maxi, with or without wings. Around the same time, feminist movements advocated for reusable options like sea sponges and cloth pads as environmentally conscious alternatives.

Menstrual Cups: A Quiet Revolution

Though menstrual cups seem like a recent innovation, the first patent was filed by Leona Chalmers in 1937. Made of latex, her design didn't gain traction due to wartime material shortages and social discomfort.

It wasn’t until 2002 that the Mooncup, a reusable silicone cup, popularized the category. Founder Su Hardy promoted it as a hypoallergenic, eco-friendly product. Unlike tampons or pads, a single menstrual cup could last up to 10 years—dramatically reducing waste. Brands like Tampax followed suit with their own versions in the late 2010s, promoting sustainability.

Late 20th Century: Safety Concerns and Regulation

The rise of toxic shock syndrome (TSS) in the late 1970s, particularly linked to super-absorbent tampons, led to thousands of hospitalizations and several deaths. This public health crisis sparked stricter regulations and awareness campaigns, including the Tampon Safety Bill (1995) and the General Product Safety Regulation (2005) in the UK.

21st Century Innovations: Empowerment and Sustainability

The last two decades have ushered in a period care renaissance. There’s a growing market for organic cotton tampons and pads, biodegradable wrappers, and subscription-based period boxes. Perhaps the biggest innovation has been period panties—moisture-wicking, antimicrobial underwear that replaces pads altogether.

Modern period brands now emphasize body positivity, gender inclusivity, and sustainability. Campaigns no longer whisper "discreet protection" but proudly celebrate menstruators taking control of their health.

Despite all the progress, menstrual stigma lingers. Even in 2025, millions of girls worldwide miss school due to lack of access to period products or sanitation. In many parts of the world, conversations around menstruation remain cloaked in secrecy or shame.

After months of steady decline, COVID-19 cases in the U.S. have begun to rise again—and no, it’s not an anomaly. This marks the anticipated beginning of a summer surge, with public health data underscoring how the virus behaves with seasonal rhythms—even while national activity levels remain low.

The Centers for Disease Control and Prevention now reports that infections are climbing in approximately half of all states, particularly throughout the Southeast, South, and the West Coast—California included. CDC’s national wastewater surveillance, which gauges virus circulation in sewage, has shifted from “very low” to “medium” activity, confirming increasing spread. In California, the WastewaterSCAN program showed the virus present at 95% of monitored sites, with concentration levels rising steadily since June.

While this escalation mirrors trends from previous summers, the data make it clear: COVID is here once again. California isn’t just another dot on the map—it’s a bellwether. With 150 COVID-related deaths per week across the U.S., even a modest surge in California can impact national outcomes. Moreover, its key role in travel, entertainment, and indoor-heavy lifestyles during heatwaves elevates the risk of amplification.

This is not a sharp spike, but a gradual climb, close to last year’s levels. That similarity should not breed complacency; rather, it offers an early chance to act.

The Rise of NB.1.8.1 (“Nimbus”) and Other Variants

Wastewater sequencing in California shows:

• LP.8.1 dominating with 33.2% of samples
• XFG at 24.6%
• NB.1.8.1, better known as “Nimbus” or the “razor‑blade throat” variant, accounting for 7.5%

Though nicknames highlight painful throat symptoms, there's no current evidence that Nimbus causes more severe illness or hospitalizations. Still, its growing prevalence and transmissibility mean health officials are tracking it closely.

CDC analysis reveals that COVID now follows a twice-yearly pattern—with surges in both summer (July–September) and winter (December–February)

San Francisco Chronicle. Researchers attribute this cycle to genetic changes in the virus’s spike protein, particularly the S1 region, which enhances viral binding and transmission.

History confirms this: California typically peaks in mid-July to late August—making current trends both expected and potentially warning signs of a broader wave.

Who’s at Risk and What You Can Do?

While activity levels are officially “low”, complacency isn’t wise—especially for high-risk groups: adults over 65, immunocompromised individuals, pregnant people, and infants under 2:

• Ensure vaccination within the past year or seek boosters
• Test if experiencing symptoms
• Wear masks in crowded or high-risk indoor spaces

As Dr. Peter Chin‑Hong of UCSF advises, “For those older than 65, very immunocompromised, pregnant persons and infants—especially under 2—I would make sure you have received a COVID vaccine at least in the past year.”

Emergency department visits for COVID remain low nationally, though recent upticks have occurred in the Pacific Northwest and Southeast—the highest since early spring. Notably, this summer rise coincides with a surge in Parvovirus B19, which poses risks for pregnant women and is prompting additional caution.

COVID hospitalizations have become more predictable with seasonal waves, but still linger above zero year-round, reinforcing the need for vigilance .

The recurring summer pattern suggests that COVID-19 is shifting from pandemic unpredictability to endemic regularity, but that doesn’t diminish its impact. Continued mutation, waning immunity, and seasonal behaviors (like travel and indoor gatherings) ensure that vigilance remains essential.

As the CDC and WHO emphasize, updating vaccines, using masks in crowded environments, testing when sick, and keeping track of local wastewater trends are practical steps everyone can take.

California’s rise in COVID cases—though still within low national activity—matters. It signals seasonal resurgence and underscores ongoing viral evolution through new variants like Nimbus. Protecting public health requires action: vaccination, testing, masking, and staying informed about evolving trends.

The summer wave is predictable—but entirely preventable in its impact. With timely measures, we can ride it out safely.
