Which of the following pairs of vector and disease is/are correctly matched?   Vector Disease 1. Anopheles Malaria 2. Aedes aegypti Chikungunya 3. Tsetse fly Filariasis 4. Bed bugs Sleeping sickness   Select the correct answer using the code given below: Correct Answer 1 and 2 only

The correct answer is 1 and 2 only.

Concept:

Vector-borne diseases

  • Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors.
  • The burden of these diseases is highest in tropical and subtropical areas.
  • Vector-borne diseases like Dengue, Malaria, Chikungunya, Yellow fever and Zika have major outbreaks since 2014.
  • Pathogen transmission mostly takes place through global travel and trade, unplanned urbanization and climate change.
  • Bed bugs are not known to spread disease. Hence 4 is incorrectly matched.

Main vectors and diseases they transmitted are:

Aedes mosquito
  • Chikungunya. Hence 1 is correctly matched
  • Dengue fever
  • Lymphatic filariasis
  • Rift Valley fever
  • Yellow fever
  • Zika

Anopheles mosquito

  • Lymphatic filariasis

  • Rickettsiosis

Black flies

 
  • Onchocerciasis (river blindness)

Lice

 
  • Typhus and louse-borne relapsing fever

Bed bugs are parasitic insects in the genus Cimex that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known as it prefers to feed on human blood. The name bed bug derives from the preferred habitat of Cimex lectularius: warm houses and especially near or inside beds or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed. A number of adverse health effects may results from bed bug bites, including skin rashes, psychological effects, and allergic symptoms. Bed bugs are not known to transmit any pathogens as disease vectors. Certain signs and symptoms suggest the presence of bed bugs; finding the adult insects confirms the diagnosis. Assuming the information in the given paragraph is true, choose the correct statement.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: For users, Facebook's revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next? For the owners of the affected accounts, and of another 40 million that Facebook considered at risk, the first order of business may be a simple one: sign back into the app. Facebook logged everyone out of all 90 million accounts in order to reset digital keys the hackers had stolen - keys normally used to keep users logged in, but which could also give outsiders full control of the compromised accounts.  Which of the following points do not capture the negligence of Facebook in the most appropriate manner? Arguments: I. What Facebook knows so far is that hackers got access to the 50 million accounts by exploiting three distinct bugs in Facebook's code that allowed them to steal those digital keys, technically known as ‘access tokens’. The company says it has fixed the bugs.  II. The hack is the latest setback for Facebook during a tumultuous year of security problems and privacy issues . So far, though, none of these issues have significantly shaken the confidence of the company's 2 billion global users.  III. One of the bugs was more than a year old and affected how the ‘View As’ feature interacted with Facebook's video uploading feature for posting ‘happy birthday’ messages. But it wasn't until mid-September that Facebook noticed an uptick in unusual activity, and not until this week that it learned of the attack.
