Vector-borne diseases are communicable (infectious) diseases that are transmitted to humans through the bite or contact with vectors—tiny living organisms like mosquitoes, ticks, flies, or fleas.
These vectors carry and spread infectious agents (viruses, bacteria, parasites) from one person or animal to another—without causing disease in themselves.
| Vector | Examples of Diseases |
|---|---|
| Mosquitoes | Malaria, Dengue, Chikungunya, Zika, Filaria, JE |
| Ticks | Lyme disease, Tick-borne encephalitis |
| Sandflies | Kala-azar (Visceral leishmaniasis) |
| Fleas | Plague, Typhus |
| Tsetse flies | Sleeping sickness (African trypanosomiasis) |
Malaria is an acute febrile illness caused by protozoan parasites of the genus Plasmodium, transmitted to humans by the bite of infected female Anopheles mosquitoes.
Malaria is both preventable and curable, but if left untreated, it can cause severe complications or death, especially in children and pregnant women.
The incubation period (time between mosquito bite and symptom onset) varies based on the Plasmodium species:
| Species | Incubation Period |
|---|---|
| P. falciparum | 9–14 days |
| P. vivax | 12–17 days (can relapse) |
| P. malariae | 18–40 days |
| P. ovale | 12–20 days |
Screening is crucial for early detection and outbreak control, especially in endemic or high-risk areas.
| Component | Details |
|---|---|
| Disease | Malaria |
| Cause | Plasmodium spp. (especially P. falciparum, P. vivax) |
| Vector | Female Anopheles mosquito |
| Transmission | Mosquito bite (main), blood transfusion (rare) |
| Incubation Period | 9–40 days depending on species |
| Screening | Fever surveillance, high-risk group testing |
| Diagnosis | Microscopy, RDTs, PCR |
Primary management focuses on early diagnosis and prompt treatment to prevent complications and break the transmission cycle.
Treatment depends on:
| Type | Treatment |
|---|---|
| P. vivax | Chloroquine + Primaquine (14 days, avoid in pregnancy) |
| P. falciparum | Artemisinin Combination Therapy (ACT) + Single-dose Primaquine |
| Severe malaria | Injectable Artesunate, supportive care |
⚠️ Primaquine is contraindicated in pregnancy and G6PD deficiency
Community nurses and health workers play a critical frontline role in malaria control and prevention:
| Primary Management | Community Nursing Management |
|---|---|
| Early diagnosis (RDT/microscopy) | Active fever surveillance during home visits |
| Antimalarial drug therapy | Administer treatment & ensure adherence |
| Supportive care | Educate on nutrition, hydration, danger signs |
| Referral for complications | Refer severe or unresponsive cases promptly |
| — | Promote vector control, bed nets, IRS |
| — | Conduct community awareness & IEC/BCC programs |
Malaria management is most effective when clinical treatment is combined with community action. Nurses are key players—not just in curing disease, but in educating, preventing, and empowering communities to fight malaria.
More common in P. falciparum infections, pregnant women, young children, and delayed treatment cases.
| System Affected | Complication |
|---|---|
| CNS (Brain) | Cerebral malaria (coma, seizures, confusion) |
| Liver | Jaundice, hepatitis |
| Kidneys | Acute renal failure |
| Blood | Severe anemia, hemolysis |
| Lungs | Pulmonary edema, respiratory distress |
| Pregnancy | Miscarriage, stillbirth, low birth weight, maternal death |
| Other | Hypoglycemia, metabolic acidosis, shock, death (if untreated) |
🛑 Severe malaria is a medical emergency—requires immediate hospitalization.
| Type of Malaria | Prognosis |
|---|---|
| P. vivax / P. ovale | Good if treated promptly (can relapse if not given primaquine) |
| P. falciparum | Potentially fatal if untreated; better prognosis with early treatment |
| Severe malaria | Poor if delayed or incomplete treatment |
| Pregnancy + Malaria | Increased risk of complications, both maternal and fetal |
📌 Prognosis is excellent with early detection and complete treatment.
Refer immediately to higher centre / hospital if patient shows:
🛑 Delay in referral can lead to fatal outcomes—always refer before patient deteriorates.
| Timing | Nursing Actions |
|---|---|
| Day 3–5 post-treatment | Check for symptom resolution, ensure drug adherence |
| After 14 days (P. vivax) | Confirm completion of primaquine course to prevent relapse |
| In pregnancy | Monitor fetal growth and anemia |
| In children | Monitor for nutritional recovery and anemia correction |
| Record-keeping | Update treatment registers, case cards, line listing |
| Health education | Reinforce use of bed nets, eliminate breeding sites, report fever |
📋 Also report cases to PHC / NVBDCP surveillance system for monitoring and epidemic control.
Timely recognition of complications, proper referral, and structured follow-up are key to preventing deaths and relapse in malaria. Nurses and community health workers play a critical role in ensuring continuity of care, family education, and community-wide prevention.
To reduce malaria transmission, prevent morbidity and mortality, and eventually achieve elimination, through individual protection, vector control, early detection, and community-level interventions.

Filaria or Lymphatic Filariasis is a chronic parasitic infection caused by thread-like filarial worms (mainly Wuchereria bancrofti, Brugia malayi, or Brugia timori) and transmitted to humans through the bite of infected Culex mosquitoes.
It affects the lymphatic system, leading to swelling of limbs (elephantiasis), genitals, and causing disability, stigma, and economic burden.
| Source | Infected human carrying microfilariae in blood |
|---|---|
| Vector | Culex quinquefasciatus mosquito (night-biting) |
| Cycle | Mosquito bites infected person → picks up microfilariae → they mature in mosquito → mosquito bites another person → larvae transmitted |
| Note | No person-to-person transmission; mosquito is essential |
Target groups for screening:
| Test | Purpose |
|---|---|
| Night Blood Smear Test | Detects microfilariae (larvae) under microscope |
| Antigen Detection Test (ICT) | Detects filarial antigens in blood at any time |
| Ultrasound of lymphatic vessels | Detects adult worms (filarial dance sign) |
| PCR (advanced) | Molecular detection, research use |
| Feature | Details |
|---|---|
| Disease | Lymphatic Filariasis (Filaria) |
| Cause | Wuchereria bancrofti, Brugia malayi |
| Vector | Culex mosquito (night-biting) |
| Incubation | 6 months to years |
| Transmission | Through mosquito bite from infected person’s blood |

Filaria does not kill, but it disables for life. With the right community action and nursing care, it is possible to control, prevent, and eliminate this disease.
Filaria leads to long-term suffering, disability, and social stigma if not managed early. Complications are mainly due to chronic lymphatic obstruction, repeated infections, and inflammation.
| System/Area Affected | Complications |
|---|---|
| Lymphatic System | Lymphedema (limb swelling), Elephantiasis (gross swelling and skin thickening) |
| Genital Organs | Hydrocele (fluid-filled swelling in the scrotum, common in men) |
| Skin & Tissue | Cracks, fungal infections, bacterial cellulitis |
| Systemic | Fever attacks (acute adenolymphangitis), psychological distress, reduced mobility |
| Social | Stigma, isolation, inability to work, loss of income |
| Stage | Prognosis |
|---|---|
| Early stage (asymptomatic) | Excellent with MDA and DEC treatment |
| Acute stage (fever, node swelling) | Good with prompt medication and care |
| Chronic stage (lymphedema, hydrocele) | No cure, but disability can be managed/prevented |
| Post-surgical hydrocele repair | Excellent recovery if surgery is timely and proper hygiene is maintained |
🔁 Long-term prognosis depends on compliance with care, hygiene, and early intervention.
Refer the patient to a PHC/CHC/District Hospital if:

Kala-azar, also known as Visceral Leishmaniasis, is a chronic parasitic disease caused by the Leishmania donovani parasite and transmitted to humans by the bite of infected female sandflies (Phlebotomus argentipes).
It primarily affects the liver, spleen, and bone marrow, and if untreated, can be fatal.
| Agent | Leishmania donovani (protozoan parasite) |
|---|---|
| Vector | Bite of an infected female Phlebotomus sandfly |
| Reservoir | Humans (in India – anthroponotic transmission, no animal host) |
| Cycle | Sandfly bites infected person → ingests parasites → parasites develop in sandfly → next bite transmits infection to another person |
📌 Transmission is not person-to-person, but vector-borne only.
Screening is essential in endemic areas (especially Bihar, Jharkhand, UP, West Bengal) and during outbreaks.
✔️ If positive + clinical signs = presumptive diagnosis
| Test | Purpose |
|---|---|
| Bone marrow or spleen aspiration | Microscopic detection of Leishmania parasites |
| PCR | Molecular confirmation (not widely available) |
| CBC, LFT | Assess anemia, liver damage, pancytopenia |

Communicable diseases : Infectious diseases
Leprosy is a chronic infectious disease caused by the bacterium Mycobacterium leprae, primarily affecting the skin, peripheral nerves, mucosa of the upper respiratory tract, and eyes.
It is not highly contagious, and with early diagnosis and multi-drug therapy (MDT), it is completely curable.
| Agent | Mycobacterium leprae |
|---|---|
| Reservoir | Infected humans (chronic untreated cases) |
| Mode of transmission | Likely via prolonged close contact, through nasal droplets or secretions |
| Not transmitted by | Casual contact, touching, or sharing utensils |
📌 Prolonged and repeated exposure is required to contract the disease.
Early detection is crucial to prevent nerve damage, disability, and stigma.
Leprosy is diagnosed clinically with support from simple field-level assessments.
A person is considered to have leprosy if they have any one of the following:
| Cardinal Sign | What to Look For |
|---|---|
| 1. Skin patch with loss of sensation | Hypopigmented or reddish patch with no pain/touch/heat feeling |
| 2. Thickened nerve with sensory/motor loss | Ulnar, lateral popliteal, facial nerves – thickened and painful |
| 3. Positive skin smear for acid-fast bacilli | Seen in multibacillary (MB) cases |
| Tool/Test | Purpose |
|---|---|
| 🧪 Skin smear microscopy | For detecting acid-fast bacilli (only in MB cases) |
| 🧪 Skin biopsy (rarely needed) | For histopathological confirmation in difficult cases |
| ✋ Sensory testing (cotton, pin, temperature) | Used in field by nurses/ANMs to assess sensation loss |

Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis, which typically affects the lungs but can also involve other parts of the body (e.g., kidneys, spine, brain).
TB spreads through the air when a person with active TB coughs, sneezes, or talks.
| Agent | Mycobacterium tuberculosis (a slow-growing bacterium) |
|---|---|
| Reservoir | Humans (infected individuals, particularly those with active TB) |
| Mode of Transmission | Spread through aerosol droplets when an infected person coughs, sneezes, or speaks |
| Not transmitted by | Touching, sharing utensils, or casual contact |
📍 Risk increases in: Crowded places, poor ventilation, immunocompromised individuals (e.g., HIV/AIDS patients)
Early detection is crucial for preventing transmission and ensuring effective treatment.
| Test | Purpose/Timing |
|---|---|
| Sputum Smear Microscopy | First line test – Detects acid-fast bacilli (AFB) in sputum; positive if 2 out of 3 smears are positive (for active TB) |
| Chest X-ray | Helps detect lung involvement; used as a secondary test for diagnosis |
| GeneXpert (CBNAAT) | Rapid PCR test – detects DNA of M. tuberculosis and rifampicin resistance (for drug-resistant TB) |
| Tuberculin Skin Test (TST) | For latent TB; tests immune response to M. tuberculosis proteins (positive indicates exposure, not active disease) |
