Arthropods as Vectors of Human Diseases | Integrated Vector Control

This article discusses about the definition of a vector, what is vector-borne diseases and the criteria of a confirmed vector. This is intended for city health officers, Dengue Program Coordinators, Nurses, and Medical Technologists working in Community Rural Health Centers in the Philippines.

I. Definition of Vector

Vector means a lot to different scientists.

  • For example in biotechnology, a vector refers to an organism or molecular vehicle used to transfer genetic material from the donor or organism to a recipient organism. 
  • This, in toto, is near the definition used in public health integrated vector control.


Vector for Mosquito-Borne Diseases is described or defined as

  • an organism capable of actively transmitting a causal agent from an infected hosts to a susceptible host.

9 Little Ways Passive Smoking is Killing Your Family

This article enumerates the dangers of passive, second-hand, or environmental tobacco smoke. The article links to relevant articles and videos about the diseases that can kill you or your family should you be exposed to hazardous cigarette smoke. The article is targeted to the general population and the terminology and language are simplified. It answers the questions related to effects of passive smoking to pregnant women, immediate and chronic (long-term) effects to children and adults, and what it does to your body.

Do you know that more than half a million people die in this world each year because of passive smoking? The World Health Organization keeps a tally. I don't make numbers up to scare people. I look up at these statistics because I wanted to know how many people you and I can save. These people died from diseases that are preventable.

The scary part is that you and I are still exposed to cigarette smoke whether we like to or not. We are exposed to its effects. Even if governments have drafted and passed laws restricting smoking in public places, there is always the problem of implementation. For example, 14 years after the passage of RA 9211, people are still smoking everywhere in the Philippines. Big important people have spoken and scared people but people will continue to smoke. And people who do not smoke will continue to die from second-hand smoke. This post will tell you how.

Arthropods as Pest | VBD

This is a short article explaining why arthropods are pests.

What are Pests? A definition.

Pests are any destructive or unwanted arthropod or other small animal (rats-mice) that causes annoyance, discomfort, or nuisance to humans or animals.

Example of arthropods as pests

Houseflies and cockroaches are the most popular among the insect pests inside and outside human dwellings.
  • They externally carry on their bodies, pathogenic agents that cause human disease,
Mosquitoes bite humans and their bites can be highly irritating and allergenic.

Arthropods - Definition

Etymology

"Arthro" means jointed; "poda" means legs

Meaning

These are insects (hexapods), spiders, arachnids, crustaceans, centipedes, and millipedes.
  • All of these are invertebrate animals (no vertebral column/ no backbone), with an outer skeleton that is toughened by a substance called chitin.
  • Arthropods are classified under Phylum Arthropoda which has five important classes of medical importance.
    • Class Insecta, is the most important class wherein mosquitoes belong.
  • Arthropods are classified according to their major body divisions and appendages.

Medical Entomology - Definition

Medical Entomology is the science which deals with the relation of insects, arachnids and other arthropods to the causation of pathological conditions in man or the transmission of pathogens that are responsible for such pathological conditions,

  • This is the science which deals with arthropods affecting human health or the study of arthropods of medical and public health importance.
  • The term "Medical Entomology" must eventually be replaced by "Medical Arthropodology" because the term "arthropodology" includes non-insects.
