If you are recovering from the flu and your fever is breaking, the chills are subsiding. But you may suddenly feel that your cough is worsening, breathing feels harder, and fatigue lingers. It could mean pneumonia! The flu and pneumonia share a complex relationship, where one can set the stage for the other. While influenza weakens the immune system, pneumonia takes advantage, causing a more severe respiratory infection. Understanding how the flu transitions into pneumonia is essential for prevention, especially for those at risk. So, how can you keep yourself safe? Let's find out the risks, warning signs, and ways to prevent and stay protected.
The flu, or influenza, is one of the common viral infections most people experience sometime in their lifetime. While most patients recover within a week or two, others develop serious complications such as pneumonia. The interplay between flu and pneumonia is quite concerning to those vulnerable groups of people such as children, elderly, pregnant women, and individuals with weakened immunity. It's essential to know how flu leads to pneumonia, recognize early signs, and take preventive measures in order to keep the respiratory health safe.
Influenza mainly infects the respiratory system, leading to an inflammatory reaction in the throat, nasal passages, and lungs. The body, in its course of operation, will most of the time end by killing the virus, hence recovering fully. However, in some cases, the flu can lead to pneumonia in two major ways:
Viral Pneumonia: The influenza virus itself can directly infect the lungs, causing pneumonia. This is known as viral pneumonia and is more common in individuals with weaker immune systems.
Secondary Bacterial Pneumonia: The flu can weaken the immune system, making it easier for bacteria to invade the lungs. This secondary bacterial pneumonia often leads to more severe symptoms and requires antibiotic treatment.
Pneumonia is an infection that inflames the air sacs in one or both lungs, filling them with fluid or pus. This makes it hard to breathe, accompanied by chest pain, fever, and a cough that may not go away. Common symptoms of pneumonia include the following:
Severe cases of pneumonia can be life-threatening, particularly for individuals with pre-existing health conditions.
| Flu | Pneumonia | |
| Cause | Influenza virus | Bacteria, viruses, or fungi |
| Symptoms | Fever, chills, sore throat, cough, muscle aches, fatigue | Fever, cough with mucus, chest pain, shortness of breath, bluish lips or nails |
| Onset | Symptoms appear suddenly | Symptoms develop gradually or after a flu infection |
| Duration | Typically 1-2 weeks | Can last for weeks, depending on severity and treatment |
| Treatment | Usually resolves on its own; antivirals in severe cases | Antibiotics for bacterial pneumonia, antivirals for viral pneumonia |
Yes, it is possible to get both the flu and pneumonia at the same time. This is when a person gets the influenza virus and later develops bacterial or viral pneumonia. Having multiple infections at the same time can greatly increase the severity of symptoms and the risk of complications. Seek prompt medical care if flu symptoms worsen or last longer than expected.
While most flu cases do not result in pneumonia, some risk factors increase the likelihood of complications:
Age: Young children and adults over 65 are more vulnerable.
Chronic Conditions: People with asthma, chronic obstructive pulmonary disease (COPD), diabetes, and heart disease are at increased risk.
Weakened Immune System: People on chemotherapy, those with HIV/AIDS, or on immunosuppressive drugs are at a higher risk.
Smoking: Smoking causes damage to the lungs, making them more prone to infections.
Hospitalization or Nursing Home Residency: The proximity of people to other sick people increases the chances of getting infections.
The best way to prevent flu-related pneumonia is to take proactive measures, including:
If flu symptoms worsen or do not improve within 7-10 days, seek medical attention to rule out pneumonia. Early diagnosis and treatment can prevent severe complications.
If flu symptoms persist or worsen after a week, it may be a sign of pneumonia. Warning signs include:

Delhi's air quality remained in "very poor" category, and the AQI stood at 342 at 8am, as per the Central Pollution Control Board. The 24-hour average AQI was logged at 412 under the "severe" category on Tuesday evening when Delhi's quality peaked to record the fourth severe air day in the month of December. With the air quality levels remaining continuously in the "very poor" category, Delhi's Chief Minister Rekha Gupta held a pollution review meet.
A review meeting was held to discuss the rising air pollution levels in Delhi on Monday at the Delhi Secretariat. The meeting was attended by the officials from various departments, which also included the Public Works Department (PWD), Transport, Delhi Pollution Control Committee (DPCC), Environment, and others.
Post meeting, Delhi Environment Minister Manjinder Singh Sirsa said that the CM sought responses from multiple departments to discuss various aspects of pollution in the national capital. Sirsa also confirmed that a follow-up meeting will be scheduled on Thursday to continue the discussions on various steps that should be taken to bring down the levels of Delhi's AQI.
On Sunday, a day before the meeting was held, Delhi's CM spoke on relying on public transport as a solution to Delhi's pollution. She said that the government aims to make the metro network "so comprehensive that people do not need to rely on private vehicles even for last-mile connectivity”.
An analysis by the Global Burden of Disease (GBD) 2023 found that air pollution is city's single largest health risk. The deaths rose from 15,786 in 2018 to 17,188 in 2023.
Another study published in Scientific Reports, a five-year study titled Respiratory Deposition of Particulate Matter in Delhi: A Five-Year Assessment of Exposure Patterns and Health Risks tracked how particulate matter settles inside the respiratory system and found that men's exposure can be up to 1.4 times higher, especially while walking or commuting. The study noted that men on average spend more time outdoors while working, commuting, or walking in traffic-heavy areas. This leads to an increase in exposure.
A different study published in Frontiers in Public Health, explored the data of 2,96,078 women and girls between the age of 16 to 55 years in Taiwan and correlated it with the long-term air pollution data between 2000 and 2013. None of these women had any history of dysmenorrhea before the survey had began.

Furthermore, a study published in Nature Communication notes that after four hours of exposure to particulate matter, it was found that people's ability to perform routine tasks and interpret emotions were highly impacted.
If Delhi is able to cut its local pollution by 50 per cent, the pollution too could drop by 50 per cent. The emission should happen across the airshed. However, the focus should be for a long-term action on the source of emission and not short-term optics like cloud seeding, smog towers, water sprinkling or air purifiers.
In fact, as per a study published in Sustainability (MDPI), an open access journal, which mapped Delhi's air quality between 1990 to 2022 and found that transports emit around 10 to 30% of pollution, whereas agricultural residue burning, which is a seasonal source of pollution leads to less than 3% of pollution, whereas firecrackers, another seasonal source, leads to less than 1% of pollution.

Do you feel an awful soar in your throat? Have you noticed that anyone you speak to are also complaining of the same symptoms? All of them, and you, seem tired, have a sore throat and no energy for days and weeks to follow. This might be what people are called "mystery disease" or the "mystery throat virus". However, this is actually the adenovirus.
Most patients with bad throat, explain experts have adenovirus, which is a common virus that spreads throughout the year. However, unlike the flu and COVID, which now have their own prescribed medicines, adenovirus has none.
Read: This Mysterious New Virus Could Spread Faster Than Covid-19 And Flu
Adenovirus is a virus that has more than 60 different strains, which is why it is able to cause a variety of symptoms. Adenovirus refers to a group of common viruses that usually trigger cold- or flu-like illness. It spreads easily because it is far more resilient than many other viruses. Ordinary soap, water, and standard disinfectants do not reliably destroy it, allowing it to persist in the environment. As a result, infections often cluster in places where people spend time close together, such as daycares and military barracks. The virus spreads through the respiratory tract, can be shed in stool, and can survive for some time on contaminated surfaces, according to the CDC.
The reason for its spread right now is due to the surge of flu cases in the southern hemisphere which has influenced the outbreaks in the northern hemisphere. Another reason is the lower flu vaccinate rates, which has now made a large number of population more vulnerable to infections, overall, including adenovirus.
While a lot of the symptoms mimics of those in flu or COVID, including shortness of breath, a sore throat and or a runny nose. However, there are certain unique symptoms of adenovirus that include:
Other rare symptoms could also include impact on your bladder or nervous system. As viruses in your bladder can also cause urinary tract infections, and the same virus in your nervous system can cause condition that can affect your brain. These conditions also include encephalitis and meningitis.

What makes this virus unique is that it can spread through easily. Adenovirus is highly contagious. It can spread from one person to another through shaking hands, kissing, or even hugging. The virus could also spread through sneezing, coughing, and if by any other means respiratory droplets transfers to other person in air. It can also spread by touching contaminated surface, and you can get the virus by touching your eyes, nose, or mouths if you do not wash your hands.
The virus can also spread through stool of an infected person. For instance, you can be infected while changing your baby's diaper. It can also spread through unchlorinated water, and a person can be infected with the virus if he or she swims in a pool without adequate chlorine.
Adenoviruses are resistant to many common disinfectants. Therefore, they can remain infectious on surfaces for a long time.
If you are generally healthy, and feel a little down, but do not have shortness of breathe or a high fever, you are safe to go, with supportive care at home. However, pay close attention to those who are already on medical attention, or those who are immunocompromised, or are infants.
If you are sick, have a high fever, and experiencing shortness of breath, it is best to consult your doctor. However, do not show up to your doctor's office, call first.

Ben Sasse, former Senator, on Tuesday shared that he has been diagnosed with pancreatic cancer. His diagnosis came at Stage 4.
The former two-term senator, 53, revealed this in a social media or X, message: “This is a hard note to write, but since many of you have already sensed something, I’ll get straight to it: Last week I was diagnosed with metastasized, stage-four pancreatic cancer, and I am going to die.”

Stage 4 cancers are terminal and his terminal diagnosis was "hard for someone wired to work and build, but harder still as a husband and a dad," he said.
Stage 4 cancers are terminal because the cancer has metastasized, which means it has spread from its original site or the primary tumor to distant organs and tissues. This makes it extremely difficult to cure with localized treatments like surgery or radiation.
However, the American Oncology Institute does note that stage 4 cancer always does not have to be terminal, especially with breakthrough treatment options like targeted therapy, immunotherapy, or precision medicine. There are now also advanced surgical techniques that use minimal invasion procedures.

According to the American Cancer Society, pancreatic cancer makes up about 3 percent of all cancers in the United States but accounts for roughly 8 percent of cancer-related deaths. Most patients are diagnosed at Stage 4, and the disease is widely regarded as largely incurable. Prostate cancer, by contrast, is the second most common cancer among men, and the majority of those diagnosed do not die from it. The five-year relative survival rate for non-metastasized prostate cancer is 97.9 percent, dropping to about 38 percent once it spreads. These figures highlight how early detection and effective treatment options make prostate cancer far more survivable than pancreatic cancer.
While treatments including chemotherapy, radiation, and in rare situations surgery are available, stage-four pancreatic cancer is still considered largely incurable. The absence of effective early screening contributes to delayed diagnosis, and although a small number of patients, such as Ruth Bader Ginsburg, have lived longer following surgery, these cases are rare. Well-known individuals including Alex Trebek and Aretha Franklin also battled the disease, which remains one of the deadliest cancers in the United States.
Former senator and former University of Florida president Ben Sasse announced on Tuesday, Dec. 23, that he has been diagnosed with terminal stage 4 cancer, as per CNN News.
In the deeply personal message, the former Republican lawmaker from Nebraska described the diagnosis as a “death sentence,” while expressing appreciation for the steady support of his family and close friends.
“I’m fortunate to have incredible siblings and half a dozen friends who are truly like brothers to me. As one of them said, ‘Yes, you’re on the clock, but all of us are.’ Death is a cruel thief, and none of us escape it,” he added.
