• Prelims & Mains – SCIENCE AND TECHNOLOGY

Context: A two-year-old child in Meghalaya has been infected with vaccine-derived polio.

Background:-

• Polioviruses are enteroviruses that are transmitted primarily by the faecal-oral route.

Vaccine-Derived Polio (VDPV):

• Vaccine-derived polio is a rare condition that occurs when the weakened (also called attenuated) strain of poliovirus used in the oral polio vaccine (OPV) mutates and regains the ability to cause paralysis.
• Mechanism:
  • OPV contains a live, attenuated virus that is used for immunisation against the disease. This weakened virus triggers an immune response when administered, thus protecting people from the disease.
  • The attenuated virus replicates in the intestines for a limited period and is excreted in the stool. In rare cases, the virus can mutate enough to cause the disease again, and circulate in areas where either immunisation is low, or where immunocompromised persons reside, or regions with poor sanitation and hygiene.
• Poliovirus Types: Three types – wild poliovirus type 1 (WPV1), wild poliovirus type 2 (WPV2) and wild poliovirus type 3 (WPV3).

About polio vaccines

• The first successful polio vaccine for poliovirus was made by Jonas Salk, in the early 1950s. Salk inactivated the virus using formaldehyde and injected it into the muscles of test subjects. This inactivated polio vaccine (IPV) induced systemic immunity in the subjects.
• After Salk, Albert Sabin developed another vaccine that contained live polio strains, weakened by growing them serially in macaque cells, making them unfit for human infection. Since this vaccine contained the live virus, it had to be administered through its natural mode of infection – in this case, oral. This is what we today know as the OPV.
• OPV is usually preferred over IPV because of its ease of administration & is inexpensive. However, the weakened virus in OPV can occasionally revert, causing the disease it is meant to prevent. IPV, on the other hand, is a less potent vaccine, but contains inactivated virus particles and hence no risk of causing vaccine-associated paralytic polio (VAPP) – a rare, adverse reaction to OPV. IPV is comparatively tougher to manufacture too.
• Vaccine-associated paralytic polio (VAPP) or vaccine-derived poliovirus (VDPV) are similar but different phenomena.
• On World Polio Day, October 24, 2019, the WHO declared that WPV3 has been eradicated worldwide. WPV2 was officially declared eradicated in 2015.
• However, more than 90% of vaccine-derived poliovirus outbreaks are due to the type 2 virus present in oral polio vaccines. VAPP constitutes 40% of cases caused by the type 2 oral polio vaccine. Many cases of VAPP from type 3 virus too occur in countries using OPV.
• The Indian government does not count VAPP as polio since these cases are sporadic and pose little or no threat to others.
• Even after the global switch from trivalent (containing all three variants) to bivalent (type 1 and type 3) oral polio vaccines in 2016 to prevent any more type 2 vaccine-derived poliovirus, the number of vaccine-derived type 2 poliovirus outbreaks have only increased sharply.

 Syllabus

• Mains – GS 2 AND GS 4

Context: Ever since the infamous gang rape that rocked the country in December 2012 (Nirbhaya), much has been done to strengthen the laws on rape. But brutal incidents of rape continuing unabated should prompt us to ask several questions regarding existing laws.

Background:

• It is no surprise that the first accused apprehended in the Kolkata rape and murder case had a history of violent assault of his wife. Yet, there was no appropriate legal response at the time despite two complaints.

Where lies the malaise & Why is the law failing to act as a sufficient deterrent?

• One answer is that laws on rape cannot be examined in isolation and be expected to regulate men’s mentality.
• Men’s brutalising of women continues to be rampant because of the laxity in laws surrounding other equally heinous crimes, which warrant immediate and equal attention as rape.

Dowry Deaths in India:

• In 2022, India recorded 6,516 annual dowry deaths, with one victim every 90 minutes. Dowry deaths are the unnatural deaths of married women due to cruelty by their husbands or in-laws.
• The conviction rate in dowry death cases is low due to the common practice of the accused paying “blood money” to the victim’s family.

Domestic Violence:

• Domestic violence is one of the most underreported crimes against women across all socio-economic backgrounds.
• The law prescribes up to three years of imprisonment for domestic violence, making it difficult for police to arrest the accused.
• Victims often see their abusers released on bail quickly due to the “bail, not jail” rule for offenses with punishments under seven years.

Other Crimes Against Women:

• Crimes like stalking or harassment are also treated leniently, allowing perpetrators to continue their behavior. Women often hear dismissive remarks from their aggressors, who feel emboldened by the lax legal system.
• There are cases where previous violent behavior, such as in the Kolkata case, did not receive appropriate legal action, leading to more severe crimes later.

Need for Legal Reform:

• A serious legal response to women’s safety requires a review of all crimes against them in order to truly inculcate society’s intolerance to any form of abuse.
• Graded penal provisions should be introduced based on the severity of the crime. Forcibly disrobing a woman or stubbornly stalking her with the intention of committing sexual assault cannot be dealt at par with milder versions of harassment.

Bail and Judicial Reform:

• The current liberal bail system is problematic without broader judicial reforms.
• In 2022, of 3,449 dowry death cases disposed of by courts, 64% were disposed of without a trial, and only 35% of tried cases led to convictions.
• There is an urgent need to develop a criminal justice system that can fast-track cases of crimes against women.
• Where protracted trials remain a stubborn challenge, a long enough incarceration, depending on the severity of the particular crime, is the only available tool to instil a fear of the law.
• Courts should strictly prohibit extrajudicial compromises that are forced on victims due to the lengthy legal process or social pressures.
• Until significant reforms are made, abusers will continue to feel empowered and unafraid of the law, perpetuating violence against women.

• Prelims – CURRENT EVENT

Context: The US centres for Disease Control and Prevention (CDC) recently issued a health advisory due to concerning rise in cases of parvovirus B19.

Background:

• The advisory highlights the importance of screening high-risk patients and taking preventive measures to reduce the spread.

About parvovirus B19.

• Parvovirus B19 is a small DNA virus.
• Parvovirus B19, also known as “slapped cheek” disease or fifth disease, is a highly contagious virus that primarily affects children but can also impact adults.
• It known as “slapped cheek” disease due to the characteristic red rash on the cheeks, and fifth disease because it was historically the fifth disease identified with a rash in children.

Transmission

• Spread: The virus spreads through respiratory droplets when an infected person coughs or sneezes. It can also be transmitted through blood transfusions and from a pregnant woman to her foetus.
• Contagiousness: Highly contagious, especially in environments like schools and daycare canters.

Symptoms

• Children: Bright red rash on the cheeks, sometimes accompanied by a lacy red rash on the body and limbs.
• Adults: Joint pain and swelling, particularly in the wrists, knees, and ankles. Some adults may also experience mild flu-like symptoms.
• Immunocompromised Individuals: Can suffer from severe anaemia due to the virus’s impact on red blood cell production.
• Pregnancy: Infection during pregnancy can lead to severe complications such as hydrops fetalis and miscarriage.

Diagnosis and Treatment

• Diagnosis: Typically made based on clinical presentation and confirmed by serologic testing for Parvovirus B19-specific antibodies. PCR testing can also detect the virus’s DNA.
• Treatment: No specific antiviral treatment. Currently, there is no vaccine available for Parvovirus B19. Preventive measures focus on reducing transmission. Management focuses on alleviating symptoms, such as using antipyretics and analgesics for children and NSAIDs for adults.

Prevention
