An electron micrograph of the measles virus. Measles is caused by the measles virus, a single-stranded, negative-sense, enveloped RNA virus of the genus Morbillivirus within the family Paramyxoviridae. [51] The virus is highly contagious and is spread by coughing and sneezing via close personal contact or direct contact with secretions. [52]
The virus causes measles, a highly contagious disease transmitted by respiratory aerosols that triggers a temporary but severe immunosuppression.Symptoms include fever, cough, runny nose, inflamed eyes and a generalized, maculopapular, erythematous rash and a pathognomonic Koplik spot seen on buccal mucosa opposite to lower 1st and 2nd molars.
This damage caused by the immune system is known as virus-induced immunopathology. [23] [24] Specifically, immunopathology is caused by the excessive release of antibodies, interferons and pro-inflammatory cytokines, activation of the complement system, or hyperactivity of cytotoxic T cells. Secretion of interferons and other cytokines can ...
Measles cases are rising in the U.S. with infections confirmed in at least five states so far this year. Cases have been reported in Alaska, Georgia, New York City, Rhode Island and Texas, mostly ...
After that it’s ready to be translated into viral proteins, wrapped in the cell’s lipid envelope, and sent out of the cell as a newly made virus. [10] Within days, the measles virus spreads through local tissue and is picked up by dendritic cells and alveolar macrophages, and carried from that local tissue in the lungs to the local lymph nodes.
The condition is caused by a bacterial infection, most commonly Staphylococcus aureus or Streptococcus pyogenes, and the bacteria enters the body through small cuts or scrapes on the skin, Dr ...
Measles was eliminated in the Americas last year, but there's one reason for lingering outbreaks. Officials: Measles outbreak caused by anti-vaccination campaign Skip to main content
Bacterial diseases – diseases caused by bacteria. Bacteriology – study of bacteria, their characteristics, growth, and role in infectious diseases. Viruses - microscopic pathogens consisting of genetic material surrounded by a protein coat, requiring living cells of host organisms to replicate. [1] Viral disease – diseases caused by viruses.
