How Climatic conditions affect the human body? Climatic conditions significantly impact the human body in various ways, influencing physiology, health, and overall well-being. Here’s how different climatic factors affect us: 1. Temperature Cold Weather : Can cause vasoconstriction (narrowing of blood vessels), leading to increased blood pressure, risk of hypothermia, frostbite, and respiratory problems. Hot Weather : Increases the risk of dehydration, heat exhaustion, heatstroke, and skin problems like sunburn. Prolonged heat exposure can strain the heart and kidneys. 2. Humidity High Humidity : Makes it harder for the body to cool down, increasing the risk of heat-related illnesses. It can also aggravate respiratory conditions like asthma. Low Humidity : Can lead to dry skin, irritated respiratory passages, and increased susceptibility to infections. 3. Air Pressure Low Pressure (High Altitude or Storms) : Can cause altitude sickness, headaches, dizziness, and...

Hi Folks!! Follow our blog on Instagram  Instagram . Human metapneumovirus (HMPV) is a virus, as the name suggests, and a common cause of respiratory illness. Scientists in the Netherlands identified it in 2001. Children, people with weakened immune systems, and adults older than 65 are most susceptible to complications from HMPV infection. Most children who become infected with HMPV are 5 years old or younger. A small number of children (5-16%) who become infected develop a lower respiratory tract infection, such as pneumonia. . Causes: HMPV is most commonly spread from person to person through close contact with someone who is infected via secretions from coughing and sneezing or by touching objects that have the virus on them. In the United States, HMPV is more likely to circulate beginning in the winter and lasting until or through the spring months.  HMPV infection can also cause asthma flare-ups or worsen COPD symptoms.  Symptoms: Most people with HMPV have mild upp...

Hi Folks!! Follow our blog on  Instagram . Vaccinology is an interdisciplinary field dedicated to the study, development, and application of vaccines to prevent infectious diseases. Here's a deeper dive into its critical aspects: Vaccine Development       1. Live-Attenuated Vaccines Contains weakened forms of the pathogen. Example: Measles, Mumps, Rubella (MMR) vaccine. Advantage: Strong immune response with long-lasting immunity. Risk: Not suitable for immunocompromised individuals.       2. Inactivated Vaccines Contain killed pathogens. Example: Polio (IPV), Hepatitis A vaccines. Advantage: Safe for most individuals. Limitation: Often require booster doses.       3. Subunit Vaccines Include only parts of the pathogen, like proteins. Example: Hepatitis B, HPV vaccines. Benefit: Minimal risk of side effects.       4. mRNA Vaccines Use messenger RNA to instruct cells to produce antigenic proteins. Example: Pfizer-BioNTech a...
