Abstract

Insights

Severe Acute Respiratory Syndrome (SARS) can present with atypical, non-respiratory symptoms. Recognizing these subtle, potentially infectious forms is crucial for public health, especially during seasonal outbreaks.

Area of Science:

  • Infectious Diseases
  • Virology
  • Public Health

Background:

  • An epidemic of atypical pneumonia, Severe Acute Respiratory Syndrome (SARS), emerged in 2002.
  • The disease spread globally, with cases reported in France linked to international travel.
  • Understanding SARS transmission dynamics is critical for pandemic preparedness.

Observation:

  • A 52-year-old patient with SARS exposure presented with fever, lymphopenia, and liver cell necrosis.
  • Initial respiratory symptoms and chest X-rays were absent, complicating early diagnosis.
  • Thoracic CT revealed subpleural ground-glass opacities, suggesting lung involvement.

Findings:

  • Early PCR testing for SARS-associated coronavirus was negative.
  • Diagnosis was confirmed retrospectively through serological analysis.
  • This case highlights incomplete or asymptomatic SARS presentations.

Implications:

  • Incomplete SARS clinical presentations pose diagnostic challenges.
  • The infectivity of asymptomatic or subclinical SARS cases remains unknown.
  • Early identification of all SARS forms, including atypical ones, is vital for controlling seasonal recurrence.

Coronavirus01:29

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
