Concerns surrounding the recent Hantavirus outbreak linked to the expedition cruise ship:
MV Hondius
have triggered comparisons with the early days of the COVID-19 pandemic.

Quarantines, international monitoring, emergency evacuations, and reports of infections aboard the ship have raised public anxiety online. However, global health officials and infectious disease experts continue to stress that the current situation is fundamentally different from COVID-19.

WHO Chief Says ‘This Is Not Another COVID’

Tedros Adhanom Ghebreyesus, Director-General of the:
World Health Organization, addressed the growing fears during an interview with CBS News.

He stated clearly:

According to Tedros, scientific evidence currently suggests:

• the outbreak risk remains low
• transmission is limited
• and the situation does not resemble the rapid global spread seen during COVID-19.

Health officials say the outbreak linked to the MV Hondius involves the:

Andes strain of hantavirus

— one of the few rare hantavirus variants known to allow limited human-to-human transmission.

What Is Hantavirus?

Hantavirus is a viral disease primarily spread through:

• contact with infected rodents
• rodent urine
• saliva
• or droppings.

Symptoms may include:

• fever
• muscle aches
• fatigue
• breathing difficulties
• nausea
• and severe lung complications.

Some forms can lead to:

Hantavirus Pulmonary Syndrome (HPS)

which can become life-threatening.

Why Experts Say Hantavirus Is Different From COVID-19

Health officials have highlighted three major differences between hantavirus and COVID-19.

1. Hantavirus Does Not Spread Easily Between People

According to experts, the biggest difference is transmission efficiency.

Unlike:
COVID-19,
which spread rapidly through airborne respiratory droplets, hantavirus transmission between humans is:

• extremely rare
• difficult
• and generally requires prolonged close contact.

Maria Van Kerkhove explained:

She clarified that the current outbreak appears largely confined to a specific environment aboard the ship.

Health authorities say transmission of the Andes strain usually requires:

• close physical proximity
• exposure to bodily fluids
• or extended caregiving contact.

2. Scientists Already Understand Hantavirus Much Better

Experts note that COVID-19 became globally dangerous partly because it was:

• a completely new virus
• poorly understood initially
• and spreading before scientists fully understood transmission patterns.

In contrast, hantaviruses have been studied for decades.

Celine Gounder explained:

Researchers already know:

• likely transmission routes
• incubation patterns
• high-risk exposures
• and prevention methods.

This allows health systems to respond faster and more effectively compared to the early COVID outbreak in 2020.

3. Hantavirus Has a Longer Incubation Period

Another major difference involves incubation time.

Experts say:

• hantavirus symptoms can take 2 to 6 weeks to appear
• whereas COVID-19 often spread within just a few days.

The longer incubation period gives authorities:

• more time for contact tracing
• isolation measures
• and monitoring exposed individuals.

According to experts, most passengers linked to the cruise outbreak are now approaching the end of the observation window without a major spike in new infections.

How Many Cases Have Been Reported?

Reports linked to the outbreak mention:

• around 10 confirmed or suspected cases
• several hospitalisations
• and at least three reported deaths.

Authorities are also reportedly monitoring:

• 18 American passengers
  who recently returned to the United States.

Despite the concern, health agencies say the overall public risk remains low.

Why the Cruise Ship Outbreak Triggered Alarm

The outbreak drew attention because the response resembled early pandemic containment measures:

• quarantined passengers
• emergency evacuations
• international alerts
• medical isolation
• and passenger tracking.

These similarities sparked public anxiety and comparisons with the COVID-19 pandemic era.

However, experts insist the scientific risk profile is very different.

Can Hantavirus Become a Global Pandemic?

At present, health experts say:

• widespread pandemic-level transmission appears unlikely
• hantavirus spreads inefficiently between humans
• and current evidence does not suggest uncontrolled global spread.

Former FDA Commissioner:
Scott Gottlieb
also noted that hantavirus:

Still, health agencies continue surveillance to monitor for:

• mutation risks
• transmission changes
• or unexpected outbreaks.

How to Reduce Risk of Hantavirus Infection

Experts recommend:

• avoiding contact with rodents
• safely cleaning rodent-infested areas
• wearing masks and gloves during cleaning
• disinfecting surfaces properly
• and seeking medical help if symptoms appear after possible exposure.

Endometriosis is often mistaken for Irritable Bowel Syndrome (IBS) because both conditions can cause bloating, abdominal discomfort, constipation, diarrhoea, and nausea.

However, health experts warn that when digestive symptoms repeatedly worsen around the menstrual cycle, the real cause may be a gynaecological condition rather than a gut disorder.

Medical professionals say this overlap is one of the key reasons why many women experience delayed diagnosis and treatment for endometriosis.

What Is Endometriosis?

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus.

These growths can develop on:

• ovaries
• fallopian tubes
• pelvic lining
• bladder
• and even parts of the bowel or intestine

The condition can lead to:

• inflammation
• severe pelvic pain
• scar tissue formation
• fertility complications
• and digestive symptoms.

Why Endometriosis Is Commonly Misdiagnosed as IBS

According to experts, bowel-related symptoms appear because endometrial tissue can affect the pelvic region and nearby digestive organs.

As a result, women may initially receive treatment for IBS instead of the underlying condition.

Professor Sangeetha K from the Department of Obstetrics and Gynaecology at Srinivas Institute of Medical Sciences and Research Centre says the symptom overlap often creates confusion during diagnosis.

Key Symptoms That May Point to Endometriosis Instead of IBS

1. Chronic Bloating (‘Endo Belly’)

Occasional bloating is common, but persistent bloating accompanied by:

• pelvic pain
• abdominal heaviness
• excessive gas

may indicate endometriosis.

Doctors say a major clue is timing.

If bloating:

• worsens before periods
• appears during menstruation
• or follows a monthly cycle

it may be hormonally linked rather than purely digestive.

2. Alternating Diarrhoea and Constipation

Changes in bowel habits are often associated with IBS.

However, in endometriosis:

• lesions may irritate the bowel
• pelvic inflammation may affect digestion
• symptoms often intensify around menstruation.

Unlike IBS, which may be triggered by stress or food, endometriosis-related symptoms often show a cyclical pattern.

3. Pain During Bowel Movements

Painful bowel movements — especially during periods — can be a major warning sign.

Experts say this may occur when endometrial tissue affects:

• the pelvic cavity
• rectum
• or lower bowel region.

Severe pain during defecation should not be dismissed as routine constipation or acidity.

4. Nausea and Vomiting Around Menstruation

Some women experience:

• nausea
• vomiting
• digestive discomfort

alongside worsening pelvic pain during the menstrual cycle.

Doctors say these symptoms may result from hormonal inflammation associated with endometriosis rather than a stomach infection or food intolerance.

Other Common Symptoms of Endometriosis

Apart from digestive symptoms, endometriosis may also cause:

• severe menstrual cramps
• heavy bleeding
• chronic pelvic pain
• lower back pain
• pain during intercourse
• fatigue
• fertility issues.

Why Early Diagnosis Matters

Experts stress that delayed diagnosis can lead to:

• worsening pain
• scar tissue formation
• fertility complications
• emotional stress
• and reduced quality of life.

Studies globally suggest many women live with symptoms for years before receiving a proper diagnosis.

How Endometriosis Is Diagnosed

Doctors may use:

• pelvic examinations
• ultrasound scans
• MRI imaging
• laparoscopy (minimally invasive surgery)

to confirm the condition.

Because symptoms overlap with digestive disorders, multidisciplinary evaluation is often necessary.

When Should You See a Doctor?

Experts recommend consulting a gynaecologist if:

• digestive symptoms repeatedly worsen around periods
• menstrual pain interferes with daily life
• over-the-counter treatments fail
• bloating becomes chronic
• or bowel pain becomes severe.

Endometriosis Awareness in India

Health experts estimate that Endometriosis affects millions of women in India, though awareness and diagnosis rates remain relatively low.

Doctors say recognising symptom patterns — especially those linked to menstruation — is critical for early intervention and better treatment outcomes.

Night shifts have become a routine part of modern work culture, especially among healthcare professionals, IT employees, factory workers, customer support staff, and emergency service providers. While many people adapt to irregular schedules for professional demands, medical experts warn that consistently disrupting the body’s natural sleep cycle may affect long-term health in ways that go beyond simple fatigue.

Researchers have spent years studying whether prolonged night shift work could increase the risk of serious illnesses, including certain cancers. Although scientists have not established a direct cause-and-effect relationship, doctors say the combination of poor sleep, circadian disruption, hormonal imbalance, and unhealthy lifestyle patterns linked to night work may gradually impact overall health.

The Body’s Internal Clock Matters More Than We Think

According to Dr Surender Kumar Dabas, Oncosurgeon and Chairman at Manipal Comprehensive Cancer Centre, the human body operates on a natural internal timing system known as the circadian rhythm.

This biological clock regulates:

• Sleep and wake cycles
• Hormone release
• Metabolism
• Cell repair
• Immune system function

When people work overnight or sleep at inconsistent times for long periods, this rhythm becomes disrupted.

Experts believe this disruption may affect:

• DNA repair processes
• Cellular regeneration
• Hormonal balance
• Inflammation control
• Immune response

Over time, these changes may contribute to increased vulnerability to various health conditions.

Is There Really a Link Between Night Shifts and Cancer?

Several international studies have explored the possible connection between long-term shift work and cancer risk, particularly breast cancer.

Some occupational health research has suggested that:

• prolonged night shift work
• repeated sleep disruption
• exposure to artificial light at night

may be associated with higher cancer risk in certain individuals.

However, scientists caution that the evidence remains inconclusive.

According to experts, current research has:

• shown mixed findings
• failed to establish definitive causation
• highlighted the need for further long-term studies

Some meta-analyses have found no strong or consistent evidence directly linking night shifts to cancer development.

Lifestyle Changes May Be the Bigger Concern

Doctors say night shifts may indirectly affect health by altering daily habits and routines.

Irregular work schedules often lead to:

• Poor eating habits
• Lack of exercise
• Increased stress
• Weight gain
• Insufficient sleep
• Higher caffeine and junk food consumption

These factors are already known contributors to chronic illnesses such as:

• Obesity
• Diabetes
• Heart disease
• Hypertension
• Certain cancers

Experts believe the overall lifestyle pattern associated with long-term shift work may play a more significant role than night work alone.

The Role of Light Exposure and Melatonin

Another area researchers continue to examine is the relationship between artificial light exposure and melatonin production.

Melatonin is a hormone naturally produced by the body during darkness and helps regulate sleep cycles.

According to doctors:

• exposure to bright light at night may suppress melatonin production
• reduced melatonin levels could potentially influence hormone regulation and immune function

Some researchers believe this may partly explain why disrupted sleep patterns are being investigated in relation to cancer risk.

Long-Term Sleep Disruption Can Affect Overall Health

Health experts warn that years of poor sleep and irregular schedules may gradually impact physical and mental well-being.

Possible long-term effects include:

• Chronic fatigue
• Reduced immunity
• Hormonal imbalance
• Digestive issues
• Mood disorders
• Increased metabolic risk

People who have worked night shifts consistently since a young age may face greater challenges maintaining balanced health over time.

How Night Shift Workers Can Protect Their Health

Doctors recommend that people working irregular schedules prioritise recovery and preventive healthcare.

Helpful habits include:

• Maintaining a fixed sleep routine whenever possible
• Creating a dark, quiet sleeping environment
• Eating balanced meals
• Exercising regularly
• Staying hydrated
• Limiting processed food and caffeine
• Scheduling regular health check-ups

Sleep quality, experts say, should be treated as seriously as diet and exercise.

The Bigger Picture

While science has not conclusively proven that night shifts directly cause cancer, doctors agree that long-term sleep disruption and unhealthy lifestyle patterns can negatively affect overall health.

The conversation around shift work is no longer just about tiredness—it is increasingly about understanding how modern work schedules interact with the body’s natural biological systems.

Because even when routines change, the body continues to keep track of stress, recovery, and rest over time.
