Disease Symptoms and Effects

A virus can slow down computer applications by consuming system resources like CPU and memory in the background. The other options describe physical hardware issues - sticky keys indicate a physical keyboard problem, loose cords are connection issues, and louder startup suggests a hardware fan problem, none of which are virus-related.

Heat stroke is characterized by dangerously high body temperature (often above 40°C), a strong full and bounding pulse due to increased cardiac output, potential delirium from brain hyperthermia, and extreme thirst. Option A describes heat exhaustion (low temp). Option C describes heat exhaustion with cramps. Option D describes shock/collapse.

Herpes (primarily oral herpes caused by HSV-1) typically presents with cold sores or fever blisters around the mouth. The related varicella-zoster virus causes shingles, a painful rash that occurs when the virus reactivates. Local irritation, itching, or tingling often precedes outbreaks. Headache can occur but is not a defining symptom compared to the characteristic skin manifestations.

Tuberculosis (TB) primarily affects the lungs, leading to a persistent cough, chest pain, and coughing up blood. Systemic symptoms include fever, night sweats, and weight loss. Sneezing and cold are typical of viral upper respiratory infections.

Tetanus is caused by Clostridium tetani bacteria which produce a neurotoxin called tetanospasmin. This toxin causes severe muscle spasms and rigidity, classically beginning in the jaw muscles (lockjaw or trismus), making it difficult or impossible to open the mouth. The muscle rigidity then spreads to other parts of the body. Cholera causes watery diarrhea, plague causes swollen lymph nodes and fever, and diphtheria causes throat membrane formation.

Feeling colour rings around a flame is a symptom of glaucoma.

Almost all infants with SCID have reduced lymphocyte counts. Remember that infants have a higher lymphocyte count range than adults by 3.5-fold.

Pain in the loin is typical of a urinary tract infection and depending on the infection, the pain may be felt anywhere from the loin to the genitalia . The pain is caused by obstruction to urine flow and subsequent distension and sometimes spasm of the ureters and collecting system upstream of the obstruction.

Guillain Barre syndrome show evidence of slowing of nerve conduction as the condition is an acute demyelinating inflammatory neuropathy affecting all peripheral nerves as well as some of the cranial nerves.

This is the correct option. Dry and loose skin is a symptom of marasmus, and not kwashiorkor.

This is not a symptom of marasmus. It is a symptom of Kwashiorkor. Thus, this is the correct option.

Yes, this is the correct answer as some possible ill-effects seen on using contraceptive methods are nausea, abdomen pain, irregular menses and breast cancer.

Acute intermittent porphyria (AIP) is characterized by abdominal pain, neuropsychiatric symptoms, and urine that darkens on standing due to porphobilinogen oxidation. Photosensitivity is NOT a feature of AIP - it occurs in cutaneous porphyrias like porphyria cutanea tarda and erythropoietic protoporphyria.

Halitosis is the medical term for bad breath, caused by poor oral hygiene, certain foods, or underlying health issues. Blood pressure (hypertension), flu, and headache are unrelated medical conditions. Note: The question has a typo 'Halitotis' instead of 'Halitosis'.

No loss of weight is observed in patients who suffer  with acute diseases.
