Have you ever been in such a deep slip and ended up waking coughing? Chances are, you choked on your own saliva. Yes, it is very much possible. Saliva is a clear liquid produced by your salivary glands that play a crucial role in digestion and oral health. This is because it washes away bacteria and food particles. The body on an average produces about 1 to 2 litres of saliva daily, and a lot of it is swallowed unconsciously. However, when saliva does not flow smoothly down the throat, it can lead to choking, which can be uncomfortable.
Here's all that you need to know about what causes it, and how can you prevent it.
This happens when the muscles that are responsible for swallowing weaken or malfunction due to health issues and the symptoms may include:
Some of the common reasons include:
Acid reflux occurs when stomach acid travels back into the esophagus and mouth, irritating the esophagus and increasing saliva production to neutralize the acid. This buildup of saliva can lead to choking.
Acid reflux can be diagnosed via endoscopy or X-rays. Treatment includes antacids to reduce stomach acid.
When you are sleeping, some abnormal swallowing can occur during that time and it may cause saliva to pool in the mouth and flow into the lungs. This is what leads to choking. This condition is often linked to obstructive sleep apnea (OSA), which causes breathing to pause during sleep.
CPAP machines to provide continuous airflow
Oral mouth guards to keep the airway open
Growths in the throat, whether benign or cancerous, can narrow the esophagus and impede swallowing.
Treatment may involve surgery, radiation, or chemotherapy, depending on the nature of the growth.
Dentures can confuse the brain into perceiving them as food and it may trigger excess saliva production and cause choking. The best way to work this out is by consulting a dentist for proper fitting and adjustment of dentures.
Conditions like Parkinson’s disease and ALS can impair the nerves that control swallowing.
Doctors may prescribe medication to reduce saliva production or teach swallowing techniques.
Excessive alcohol consumption can relax throat muscles, allowing saliva to pool and cause choking.
Moderate alcohol intake and sleep with your head elevated.
Speaking continuously without pausing to swallow can lead to saliva entering the windpipe.
Take pauses to swallow while talking.
Thickened saliva or mucus due to allergies or infections can obstruct the throat, especially during sleep.
Antihistamines, cold medication, or antibiotics may be prescribed, depending on the underlying cause.
In case of sleep apnea, sleep with your head elevated or on your side. You can also try and avoid lying flat right after eating and eat smaller meals to prevent acid reflux. It is also important that you sip water throughout the day to clear any saliva buildup. In severe cases, use over-the-counter medicines for allergies or consult a healthcare provider.

Dengue has become one of the fastest-emerging health crises in the urban parts of India. Every year during the monsoon season, the number of dengue cases rises dramatically in many Indian cities, posing a huge burden on the healthcare sector.
Though climate and mosquitoes are usually cited as reasons for the surge in dengue cases, the problem actually lies in how urban life and the infrastructure of the cities have changed over the decades.
The dengue virus is spread through the Aedes aegypti mosquito that lives well in fresh still water, which is abundant in urban areas.
Mosquitoes breed in construction sites, open water tanks, old plastic buckets, flower pots, coolers, water stored on roofs, and blocked drainage systems. Due to the growing size of cities and high population density, mosquito-borne diseases have become more common.
There are many factors that contribute to the rise in the number of dengue patients, one of which is unplanned city expansion. The fast pace of development in the cities results in stagnant water in the construction areas going unnoticed for weeks.
Moreover, improper drainage and a lack of sanitation facilities help mosquitoes breed. Even posh societies and offices can suffer if proper checks are not conducted.
Urban lifestyle trends also act as indirect factors contributing to the issue. Longer working hours, higher levels of indoor activities, and reliance on mechanical ventilation lead to less focus on environmental hygiene issues.
Families tend to take mosquito prevention steps only after an outbreak starts. The overuse of plastics and poor waste management practices in urban areas have exacerbated waterlogging problems.
The situation has been exacerbated by climate change and global warming. Mosquitoes can breed at a faster pace and survive for a longer period of time in the warm climate and unpredictable rain patterns. Another factor that plays an important role is urban heat islands, which refer to places that are hotter because of man-made concrete buildings.
In order to curb the incidence of dengue, there must be an all-around transformation, both on the part of the governing authorities and the people. Firstly, urban planning should take into consideration good drainage facilities, frequent fogging, garbage disposal services, and proper regulation of building sites. Secondly, there must be frequent checks in residential areas, schools, offices, markets, and open public areas.
Secondly, the awareness campaign needs to be practical and more community-oriented. The citizens should realize that the prevention of dengue starts from their homes. Actions like washing the coolers once a week, covering the water tank, not allowing the water to stagnate, and using mosquito repellents will go a long way in minimizing the spread of dengue.
Healthcare preparedness is also equally important. The early detection and proper treatment of dengue could help avoid any serious complications. One should never overlook symptoms like fever, body pain, headache, rashes on the skin, nausea, and weakness during the rainy season.
Combatting dengue fever is no longer just a matter of health care but rather a question of urban planning and lifestyle issues. As the cities continue to expand, everyone should unite and come up with healthier and more environmentally friendly cities. Otherwise, we may see more recurring problems of dengue outbreaks in urban settings every year.

Amid growing discussions around hantavirus transmission through body fluids, experts today stressed that cases involving transmission through breast milk or semen remain extremely rare and should not trigger unnecessary panic.
The discussions began after a 2023 study published in the journal Viruses found that the Andes strain of the rat-borne virus can persist in human semen for up to six years.
More concerning was the possibility that the virus could potentially be transmitted sexually even after a person has recovered, according to the peer-reviewed study.
The research, conducted by Swiss scientists at Spiez Laboratory, suggested that hantavirus may survive in the male reproductive tract like viruses such as Ebola.
“Taken together, our results show that the Andes virus has the potential for sexual transmission,” the study said. However, to date, no confirmed case of such transmission has been documented.
Why Viral RNA Can Persist In Semen
Speaking to HealthandMe, Dr. Rajeev Jayadevan, convenor of the IMA research cell, explained that the detection of Andes virus RNA — the hantavirus strain linked to the recent MV Hondius cruise ship outbreak — in semen long after recovery is not entirely unexpected.
“The finding of RNA belonging to the Andes virus in human semen long after recovery is no surprise. In fact, this is a well-described scenario in at least 27 different viruses, including Zika and Ebola,” he said.
He explained that viruses reaching the testis enter what is known as an “immune-privileged” site protected by the blood-testis barrier (BTB).
“The testis is naturally shielded from the body’s immune system to protect newly formed sperm cells from being recognised and destroyed as ‘foreign’,” Dr. Rajeev said.
According to the expert, many viruses take advantage of this natural immune protection, allowing them to remain in the area longer than expected.
However, he clarified that although researchers detected viral RNA in semen, the virus itself could not be cultured, meaning there is no proof that the infectious virus remained present.

Another study published in Emerging Infectious Diseases, a monthly open-access peer-reviewed medical journal published by the US Centers for Disease Control and Prevention, highlighted the risk of mother-to-child transmission of the Andes strain of hantavirus through breast milk.
Andes virus (ANDV) is the only hantavirus known to spread between humans through close contact.
“We detected the genome and proteins of ANDV in breast milk cells from an infected mother in Chile who transmitted the virus to her child, suggesting gastrointestinal infection through breast milk as a route of ANDV person-to-person transmission,” the study said.
Epidemiologist Dr. Amitav Banerjee, professor at DY Patil Vidyapeeth, Pune, told HealthandMe that while isolated cases of hantavirus transmission from mother to child through breast milk have been reported, they are highly uncommon.
“These cases of hantavirus transmission through breast milk from mother to child are very rare. As a general rule, there is no need to worry excessively,” he said.
According to him, mothers experiencing fever during the acute stage of illness may temporarily avoid breastfeeding because viral load tends to be highest during active infection and just before symptoms appear. However, he stressed that breastfeeding should not be stopped routinely out of fear.
Dr. Amitav explained that the situation is somewhat comparable to HIV transmission through breast milk, which also occurs in less than 1 percent of cases. Despite that, mothers in many developing countries are still advised to continue breastfeeding because the health risks of depriving infants of breast milk are often greater than the risk of viral transmission.
He noted that hantavirus differs significantly from HIV because it is generally an acute and transient infection, unlike HIV, which persists lifelong in body fluids.
“Hantavirus infection is acute and transient, whereas HIV is lifelong,” he said, adding that hantavirus usually clears from the body after recovery, including from semen and other body fluids.
Sexual Transmission After Recovery Still Unclear
Dr. Rajeev noted that the Andes virus spreads primarily through close contact and shared personal space while a patient is symptomatic.
“Whether it can be sexually transmitted long after recovery remains unknown,” he said.
Overinterpreting RT-PCR Results
Dr. Amitav also cautioned against overinterpreting isolated reports of viral detection in semen or breast milk.
According to him, RT-PCR tests are extremely sensitive and may detect dead viral particles even after the infection has resolved. Therefore, a positive RT-PCR result does not necessarily mean that a person remains infectious.
“In fact, RT-PCR is highly sensitive and often used more for research and surveillance purposes. Detecting viral material does not always indicate active infection or transmission risk,” he said.
He added that hantavirus does not appear to persist as an infectious virus for a long period after recovery and that there is currently no strong evidence supporting long-term transmission once a patient has recovered.

India has recorded 6,927 dengue cases and 10 deaths so far in 2026, according to the latest data from the National Centre for Vector Borne Diseases Control (NCVBDC).
According to the provisional data as of February this year, Tamil Nadu reported the highest number of cases at 2,873, followed by Maharashtra with 786, Kerala with 670, Karnataka with 560, and Andhra Pradesh with 448 cases. During the same period, Kerala reported nine deaths, while Tamil Nadu reported one death.
According to the Ministry of Health, the Case Fatality Rate (deaths per 100 cases) for dengue has remained below 1 per cent since 2008 and stood at 0.13 per cent in 2024.
The dengue burden in India has steadily increased over the past few years:
| Year | Cases | Deaths |
| 2021 | 193,245 | 346 |
| 2022 | 233,251 | 303 |
| 2023 | 289,235 | 485 |
| 2024 | 233,519 | 297 |
| 2025 | 121,824 | 131 |

National Dengue Day: History And Theme
Launched in 2010, National Dengue Day is observed every year on May 16 as a pre-monsoon alert to help communities prepare before mosquito breeding peaks.
“On National Dengue Day, let us unite to spread awareness about dengue prevention and keep our surroundings clean and safe. The Government of India continues to strengthen dengue control through better surveillance, testing, improved treatment, and awareness campaigns,” said Jagat Prakash Nadda on the social media platform X.
“This year’s theme, ‘Community Participation for Dengue Control: Check, Clean and Cover,’ reminds us that community action is key to defeating dengue,” he added.
Dengue Vaccines In India

Notably, India is currently developing an indigenous dengue vaccine that is undergoing clinical trials.
“The trials will take at least two and a half years, which means by the end of 2028, we will have the results,” said Dr. N K Arora, Member of the National Technical Advisory Group on Immunization in India (NTAGI), speaking to HealthandMe.
He highlighted the severity of dengue when it progresses from a mild illness to a severe one, particularly among young adults.
The vaccine is expected to play a crucial role in protecting the 10–20 age group, which is considered more susceptible to severe dengue cases.

“We are waiting for the results of the trials, and once the vaccine is recommended by the NTAGI, the system will be ready to adopt it,” Dr. Arora added.
Meanwhile, Qdenga, a dengue vaccine developed by the Japanese pharmaceutical company named Takeda Pharma, is expected to be rolled out soon in the country.
The vaccine TAK-003 will be available in India through a manufacturing partnership with Hyderabad-based Biological E (Bio E), in line with the 'Make in India' initiative.
Dengue is a viral infection transmitted primarily by Aedes mosquitoes and is common in tropical and subtropical regions worldwide.
Mild dengue causes high fever and flu-like symptoms. However, in some cases, it can progress to severe dengue, also known as dengue hemorrhagic fever, which may lead to serious bleeding, shock, and death.
Dengue is considered the most prevalent viral infection transmitted by Aedes mosquitoes. More than 3.9 billion people across over 132 countries are at risk, with an estimated 96 million symptomatic cases and around 40,000 deaths annually worldwide.
Symptoms usually appear 4–10 days after being bitten by an infected mosquito and may vary in severity. Common symptoms include:
In severe cases, dengue may cause excessive bleeding, a sudden drop in blood pressure, and organ complications.
Preventing dengue mainly involves reducing mosquito exposure and eliminating mosquito breeding sites. Effective preventive measures include:
