Population dynamics and health implications include factors such as migration, sanitation, growth, climate, infectious diseases, accidents, overcrowding, occupational hazards, winter, rainfall, asthma, malaria, diarrhea, allergic reactions, and viral hemorrhagic fever. Climate-related diseases include malaria, asthma, winter-related illnesses, allergies, and diarrhea. Public health interventions for these diseases involve using safe water, personal cleaning, health awareness, vector reduction, treating underlying causes, appropriate medical treatment, sufficient living space, chemical prophylactics, immunization, and environmental cleaning programs.
4. Malaria
• Definition:
From the Italian “mal aria” -Bad Air
• Also known as ague, marsh disease Of
the nine sub-genera, there are four
that are typically parasitic to humans
– P. falciparum
– P. vivax
– P. malariae
– P. ovale
• Management :
– Prevent vector development
– Prevent breeding
– prevent biting
– Treatment of infected people
5. Asthma
• Etiology:
o is a chronic inflammatory disorder
of airways that result in airway
obstruction in response to external
stimuli, causing difficulty in
breathing, with expiratory
wheezing.
provoked by exercise, cold weather,
smoking, infection or psychological.
Management :
– prevent exposure
– Reduce risk factor
– Actual management
6. Allergic rhinitis
• Definition
– Rhinitis is inflammation of the nasal
lining which comprises a group of
symptoms including nasal congestion,
itching, redness, sneezing, and
rhinorrhea (runny nose).
– Food allergy is an abnormal response
to
a food triggered by your body's immune
system.

– Most common cause
–Of dehydration in type
electrolyte loss.
Etiology:-
–Infection
–Hot water
–Toxin
–Management:
• Using safe water
• Personal cleaning
• Health awareness
8. Public health intervention
