Dengue (pronounced DENG-gay) can affect anyone but tends to be more severe in people with compromised immune systems. Because it is caused by one of four serotypes of virus, it is possible to get dengue fever multiple times. However, an attack of dengue produces immunity for a lifetime to that particular serotype to which the patient was exposed.
Dengue virus rarely causes death. However, the infection can progress into a more serious condition known as severe dengue or dengue hemorrhagic fever. Symptoms of dengue hemorrhagic fever include: bleeding under the skin. frequent vomiting.

From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
2. Introduction
• Fever Dengue (pronounced DEN-gee) is caused by
viruses that are transmitted by mosquito bites.
• Aedes aegypti is the mosquito that most commonly
spreads this disease through its bite.
• It is a severe illness with symptoms as fever,
headache, intense muscle and joint pains,
exhaustion, lymphadenopathy (swollen glands) and
rashes.
3. • There are other name for dengue is
"breakbone."
• Because dengue fever is caused by a virus,
there is no specific medicine or antibiotic to
treat it.
• For typical dengue fever, the treatment is
directed toward relief of the symptoms
(symptomatic treatment).
• The acute phase of the illness with fever lasts
about one to two weeks.
4. • Dengue can affect anyone but tends to be more
severe in people with compromised immune
systems.
• Because it is caused by one of five serotypes of
virus, it is possible to get dengue fever multiple
times.
• However, an attack of dengue produces
immunity for a lifetime to that particular viral
serotype to which the patient was exposed.
5. Epidemiology of dengue fever
• Dengue is prevalent throughout the tropics and
subtropics.
• Dengue is also known as “breakbone fever”
because of the intense joint and bone pain
caused by the infection.
• About 40 percent of the world is currently at
risk for dengue.
• Only forty years ago, according to the WHO,
there were only nine countries worldwide that
experienced severe dengue epidemics.
• Today, the WHO estimates between 50 and 100
million dengue infections every year, and
dengue is endemic in over 100 countries
worldwide.
6. Causes of dengue fever
• It is caused by the following four serotypes:
– DENV-1,
– DENV-2,
– DENV-3, and
– DENV-4 (the numbers reflect the order of discovery
and have no relation to disease severity)
• These four serotypes originated in monkeys and jumped
to humans in tropic and sub tropic regions over a
century ago.
• However a fifth type has been discovered by Nikos
Vasilakis, PhD of the University of Texas Medical
Branch in Galveston:
– DENV-5
7. How dengue spreads?
• The virus is contracted from the bite of a
striped Aedes aegypti mosquito that has
previously bitten an infected person.
• The mosquito flourishes during rainy seasons but
can breed in water-filled flower pots,
plastic bags, and cans year-round. One mosquito
bite can cause the disease.
• The virus is not contagious and cannot be spread
directly from person to person. There must be a
person-to-mosquito-to-another-person pathway.
8. What are dengue fever signs and symptoms?
• After being bitten by a mosquito carrying the
virus, the incubation period ranges from three
to 15 (usually five to eight) days before the
signs and symptoms of dengue appear in
stages.
9. The signs and symptoms are as follows:
• Sudden onset of fever for 2 to 7 days
(40 C)
• Severe headache with retro-orbital (behind
the eye) pain
• Joint and muscle pain
• Skin rashes
• Nausea and vomiting
• Bleeding from the nose or gums or easy
bruising in the skin
10. Treatment
• There are currently no licensed dengue vaccines
available. Several vaccine candidates are in clinical
or pre-clinical development.
• The most advanced candidate, a chimeric tetravalent
vaccine based on the yellow fever 17d backbone, is
currently under evaluation in Phase III clinical trials.
• Prevention is currently the best method of dengue
control
• For typical dengue, the treatment is concerned with
relief of the symptoms.
11. • Bed rest and mild analgesic-antipyretic therapy are
often helpful in relieving lethargy, malaise, and fever
associated with the disease.
• Aspirin and non steroidal anti-inflammatory drugs
should only be taken under a doctor's supervision
because of the possibility of worsening bleeding
complications.
• Acetaminophen (paracetamol) and codeine may be
given for severe headache and for joint and muscle
pain (myalgia).
12. • Oral rehydration therapy is recommended for
patients with moderate dehydration caused by
high fever and vomiting.
• Patients with known or suspected dengue fever
should have their platelet count and hematocrit
measured daily from the third day of illness
until 1-2 days after defervescence.
13. • Patients with clinical signs of dehydration and
patients with a rising hematocrit level or falling
platelet count should have intravascular volume
deficits replaced under close observation.
• Those who improve can continue to be
monitored in an outpatient setting, and those
who do not improve should be admitted to the
hospital for continued hydration.
14. When to admit the patient?
• BP < 90/60 mm Hg
• HCt > 50 %
• Platelets < 50,000/cu.mm
• Bleeding other than petechiae
• When danger signs develop
15. Factors that affect disease severity include
the following:
• Patient age
• Pregnancy
• Nutritional status
• Sequence of infection with different dengue
serotypes
• Hepatic failure
• Virus genotype
• Quality and extent of available medical care
16. Prevention
• Stay in air-conditioned or well-screened
housing. It's particularly important to keep
mosquitoes out at night.
• Reschedule outdoor activities. Avoid being
outdoors at dawn, dusk and early evening, when
more mosquitoes are out.
• Wear protective clothing. When you go into
mosquito-infested areas, wear a long-sleeved
shirt, long pants, socks and shoes.
17. • Use mosquito repellent. Permethrin can be applied
to your clothing, shoes, camping gear and bed
netting. You can also buy clothing made with
permethrin already in it. For your skin, use a
repellent containing at least a 10 percent
concentration of DEET.
• Reduce mosquito habitat. The mosquitoes that
carry the dengue virus typically live in and around
houses, breeding in standing water that can collect in
such things as used automobile tyres. Reduce the
breeding habitat to lower mosquito populations.
18. Summary
• Dengue is an infectious disease caused by a virus.
• You can get it if an infected mosquito bites you.
• It is common in warm, wet areas of the world.
• Outbreaks happen in the rainy season.
• Most people with dengue recover within 2 weeks.
• However, some dengue infections are severe and
cause bleeding from your nose, gums or under
your skin.
• Early diagnosis and treatment of dengue is critical
as epidemics of the disease become larger and
more frequent.
19. • An estimated 50 to 100 million people are infected
with dengue each year in over 100 countries.
• In severe cases, people infected with dengue may
experience severe bleeding, shock and death.
• Severe dengue is often treated with
aggressive emergency treatment, which includes
fluid and electrolyte replacement.
• Prompt treatment can be life saving. Dengue can be
prevented by limiting exposure to
the mosquitoes that carry the virus.
