Incubation period (also known as the latent period or latency period) is the time elapsed between exposure to a pathogenic organism, a chemical, or radiation, and when symptoms and signs are first apparent. [1] In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold ...
59,000 per year worldwide [ 6 ] Rabies is a viral disease that causes encephalitis in humans and other mammals. [ 1 ] It was historically referred to as hydrophobia ("fear of water") due to the symptom of panic when presented with liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. [ 1 ]
Influenza vaccine. Influenza vaccines, colloquially known as flu shots, are vaccines that protect against infection by influenza viruses. [14][15] New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. [14] While their effectiveness varies from year to year, most provide modest to high protection ...
The disease is usually more severe in adults than in children. [9] Chickenpox is an airborne disease which easily spreads via human-to-human transmission, typically through the coughs and sneezes of an infected person. [5] The incubation period is 10–21 days, after which the characteristic rash appears. [2]
1984 – First vaccine for chicken pox. 1985 – First vaccine for Haemophilus influenzae type b (HiB) 1989 – First vaccine for Q fever [12] 1990 – First vaccine for hantavirus hemorrhagic fever with renal syndrome. 1991 – First vaccine for hepatitis A [13] 1998 – First vaccine for Lyme disease.
The DPT vaccine or DTP vaccine is a class of combination vaccines to protect against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus (lockjaw). [7] The vaccine components include diphtheria and tetanus toxoids, and either killed whole cells of the bacterium that causes pertussis or pertussis antigens.
The rabies vaccine is a vaccine used to prevent rabies. [11] There are several rabies vaccines available that are both safe and effective. [11] Vaccinations must be administered prior to rabies virus exposure or within the latent period after exposure to prevent the disease. [12] Transmission of rabies virus to humans typically occurs through a ...
58,700 (2015) [9] Whooping cough (/ ˈhuːpɪŋ /), also known as pertussis or the 100-day cough, is a highly contagious, vaccine-preventable bacterial disease. [1][10] Initial symptoms are usually similar to those of the common cold with a runny nose, fever, and mild cough, but these are followed by two or three months of severe coughing fits. [1]
